APPEARING: For the Appellant: Bruce Kaun, Counsel For the Respondent: Joe McBride, Counsel APPEAL This is an appeal against the May 19, 1998, decision of the Deputy Director of Wildlife denying Allan John a permit to possess three east African Gaboon vipers (Bitis gabonica gabonica) and three west African Gaboon vipers (Bitis gabonica rhinoceros). The Environmental Appeal Board has the authority to hear this appeal under section 11 of the Environment Management Act and section 101.1 of the Wildlife Act. Mr. John seeks an order allowing him to possess Gaboon vipers. BACKGROUND Gaboon vipers are native to west and central Africa, western east Africa, southern Tanzania, parts of Zambia, northern Zimbabwe and northern Natal. They grow to approximately 2 metres in length, and are considered the largest vipers in the world by weight. Their colour and pattern is vivid and striking with many shades of purples, browns, creams, and other subtle colour combinations in a complex arrangement of geometric shapes, somewhat like an oriental carpet. Their fangs are about 5 centimetres long and their venom is fatal without sufficient quantities of the appropriate antivenin. Mr. John has been interested in snakes since he was about 7 or 8 years old and has possessed snakes since 1989. He currently possesses 18 snakes, the largest of which is about 12 feet in length and the most poisonous of which is about as toxic as a bee sting. The snakes are kept in cages in his living room and in a locked APPEAL NO. 98-WIL-24 Page 2 bedroom of the trailer in which he lives in Chetwynd, British Columbia. Mr. John makes educational presentations with live snake specimens to students from elementary schools, high schools and colleges in several towns in northeastern British Columbia. He also shows his snakes to the community at large during the “Family Fest” in the spring and during “Ghoulish Affair” in the fall. In the fall of 1996, Mr. John applied to Andy Ackerman, the Regional Manager for Fish and Wildlife in Fort St. John, for a permit to import and possess three east African Gaboon vipers and three west African Gaboon vipers. The reasons that Mr. John gave for wanting to acquire Gaboon vipers were to add to his educational presentation, to breed and sell to universities, and to eventually milk the snakes for venom that he could sell. The permit was refused on October 8, 1996. This decision was appealed to the Deputy Director. The Deputy Director stated that Gaboon vipers fall into the family “Viperidae - pit vipers” and are therefore prescribed as “wildlife” under the Designation and Exemption Regulation, B.C. Reg. 168/90. The Deputy Director found that the Ministry of Environment, Lands and Parks had “made a policy decision to not allow the private possession of venomous snakes except in extenuating or special circumstances.” He was “convinced that no special circumstances exist that should allow Mr. John to be given a possession permit in these circumstances.” RELEVANT LEGISLATION Section 33(1) of the Wildlife Act states: A person commits an offence if the person has live wildlife in his or her personal possession except as authorized under a licence or permit or as provided by regulation. Mr. John applied for a permit to import and possess the snakes under sections 19 (general permits) and 21 (import and export of wildlife) of the Act: 19 (1) A regional manager …may, to the extent authorized by and in accordance with regulations made by the Lieutenant Governor in Council, by the issue of a permit, authorize a person (a) to do anything that the person may do only by authority of a permit or that the person is prohibited from doing by this Act or the regulations, or … subject to and in accordance with those conditions, limits and period or periods the regional manager may set out in the permit and, despite anything contained in this Act or the regulations, that person has that authority during the term of the permit. 21 (1) Except as authorized by a permit issued under this Act or under the Convention on International Trade in Endangered Species of Wild Fauna and Flora, a person commits an offence if the person (a) imports into British Columbia live wildlife, or the egg of a wildlife species, APPEAL NO. 98-WIL-24 Page 3 The term “wildlife” is defined under section 1 of the Act as “raptors, threatened species, endangered species, game or other species of vertebrates prescribed as wildlife...”. There is no evidence that the snake at issue in this appeal is a raptor, threatened or endangered species or game. Therefore, if it is “wildlife” under the Act, it must fall under “other species of vertebrates prescribed as wildlife”. The Designation and Exemption Regulation of the Act states: 1. The vertebrates listed in Schedule A are prescribed as wildlife for the purposes of the definition of “wildlife” in section 1 of the Wildlife Act. Section 1(v) of Schedule A of the Designation and Exemption Regulation specifies that “all species of the family Viperidae - pit vipers” are prescribed as wildlife within the province of British Columbia. ISSUES The Panel has identified the issues in this appeal as follows: 1. Whether Gaboon vipers fall under section 1(v) of Schedule A of the Designation and Exemption Regulation and are therefore regulated as “wildlife” under the Wildlife Act. 2. If not, whether any other section of the Wildlife Act or of Ministry of Environment, Lands and Parks policy prohibits the possession of venomous snakes DISCUSSION AND ANALYSIS 1. Whether Gaboon vipers fall under section 1(v) of Schedule A of the Designation and Exemption Regulation and are therefore regulated as “wildlife” under the Wildlife Act. As noted above, section 1(v) of Schedule A of the Designation and Exemption Regulation states that “all species of the family Viperidae - pit vipers” are prescribed as wildlife within the province of British Columbia. This is the section used by the Deputy Director to determine that the Gaboon viper is “wildlife” under the Wildlife Act and therefore requires a permit to be imported and possessed. Originally, the Appellant accepted that the Gaboon viper fits within this designation. However, in the course of the hearing before the Board, a question arose as to whether this viper does, in fact, properly fall under this section. The question initially arose when it was noted that the terms “pit viper” and “Viperidae” are not synonymous in that Gaboon vipers are Viperidae, but are not pit vipers. Thus, did the legislature intend for snakes such as Gaboon vipers to be captured by this section? To determine the intent of the legislature, it is necessary to define the terms “Viperidae” and “pit viper” and also examine the context within which these terms are used. It was noted that the taxonomic system used in the regulation under the Alberta Wildlife Act subdivides Viperidae into three subfamilies, one of which is the APPEAL NO. 98-WIL-24 Page 4 subfamily Viperinae which includes genus Bitis (Gaboon vipers). This Regulation then distinguishes pit vipers as a separate family, Crotalidae. Alberta Legislation Family: Viperidae (vipers and adders) Subfamily: Viperinae Species: Bitis gabonica gabonica Bitis gabonica rhinoceros Family: Crotalidae (pit vipers) Under this system the terms “Viperidae” and “pit viper” (Crotalidae) are mutually exclusive. Because of the use of both “pit viper” and “Viperidae” in section 1(v), it could be argued that both families are meant to be captured by the section. However, another taxonomic system, described in “The Encyclopaedia of Snakes” by Chris Mattison, includes pit vipers as a subfamily within the Viperidae family. In this system, family Viperidae is subdivided into four subfamilies. The pit viper subfamily is Crotalinae. The Gaboon viper is included in the subfamily Viperinae (as above). Encyclopedia of Snakes Family: Viperidae (vipers, adders, and pit vipers) Subfamily: Viperinae Species: Bitis gabonica gabonica Bitis gabonica rhinoceros Subfamily: Crotalinae (pit vipers) If this system is used to interpret section 1(v), it is arguable that by referring to “Viperidae – pit viper” the legislature intended to limit what is captured by the broader family name (Viperidae), to only one of the subfamilies – pit vipers or Crotalinae. The Panel requested and received additional written submissions from the parties on this matter. From the submissions it appears that the following can be said: “Viperidae” is the scientific name for the family of snakes commonly known as vipers and adders. It includes three or four subfamilies, depending on which classification system is used. Gaboon vipers (Bitis sp.) are a member of the Viperinae subfamily. “Pit viper” is a common name, describing a type of viper that has heat-sensing pits on the side of the face. They are recognized either as a subfamily within the Viperidae family (Crotalinae) or as a separate family altogether (Crotalidae). Regardless of the taxonomic system used, there is no dispute that the Gaboon viper does not have a heat-sensing pit on the side of its face and is, therefore, not a member of this family or this subfamily.

Kemp-Harper1, Anjana Silva 1,2, Sanjaya Kuruppu3, Geofrey K. Isbister 1,4 & Wayne C. Hodgson1* We investigated the cardiovascular efects of venoms from seven medically important species of snakes: Australian Eastern Brown snake (Pseudonaja textilis), Sri Lankan Russell’s viper (Daboia russelii), Javanese Russell’s viper (D. siamensis), Gaboon viper (Bitis gabonica), Uracoan rattlesnake (Crotalus vegrandis), Carpet viper (Echis ocellatus) and Puf adder (Bitis arietans), and identifed two distinct patterns of efects: i.e. rapid cardiovascular collapse and prolonged hypotension. P. textilis (5 µg/kg, i.v.) and E. ocellatus (50 µg/kg, i.v.) venoms induced rapid (i.e. within 2 min) cardiovascular collapse in anaesthetised rats. P. textilis (20 mg/kg, i.m.) caused collapse within 10 min. D. russelii (100 µg/kg, i.v.) and D. siamensis (100 µg/kg, i.v.) venoms caused ‘prolonged hypotension’, characterised by a persistent decrease in blood pressure with recovery. D. russelii venom (50 mg/kg and 100 mg/kg, i.m.) also caused prolonged hypotension. A priming dose of P. textilis venom (2 µg/kg, i.v.) prevented collapse by E. ocellatus venom (50 µg/kg, i.v.), but had no signifcant efect on subsequent addition of D. russelii venom (1 mg/kg, i.v). Two priming doses (1 µg/kg, i.v.) of E. ocellatus venom prevented collapse by E. ocellatus venom (50 µg/kg, i.v.). B. gabonica, C. vegrandis and B.

Alexandru STRUGARIU* & Ştefan R. ZAMFIRESCU “Alexandru Ioan Cuza” University, Faculty of Biology, Carol I Blvd. No. 20 A, 700506, Iaşi, Romania. * Corresponding author’s e-mail address: [email protected] Abstract. The ecological advantages and disadvantages of melanism in reptiles, especially in the adder (Vipera berus (L. 1758)), have been intensively studied over the years. General consideration would agree that, in most cases, adders which go on to become melanistic, are born cryptic, with a typical zigzag pattern, and darken with age, becoming black in the second or third year of life. In the present note we report the second known case in which a cryptic female adder gave birth to a melanistic neonate. Based on the fact that the observed body mass (7 g) of the melanistic neonate lies beyond the upper 95% confidence zone of the expected body mass (5.74g ± 0.977) calculated using the linear regression model from the cryptic neonates for a snout-vent length of 175 mm, and on the supporting literature, we propose a new hypothesis (which should be tested in future studies) according to which, melanistic adders may benefit of a significant higher fitness since birth. Key words: reptiles, colour polymorphism, reproduction, new hypothesis, body size, fitness advantage The coloration of animals is considered 2003). Although generally rare in reptiles, to be an adaptation to different biotic and melanism has been reported to be locally abiotic environmental factors.

  • Venomous Snakes
    Venomous Snakes - By Kedar Bhide Kedar Bhide is a snake expert from Mumbai. A postgraduate from Mumbai's Haffkine Institute, his work has resulted into first records of 2 snake species for India, Barta (Kaulback's Pit Viper) from Arunachal Pradesh and the Sind Awl-headed snake from Rajasthan. “ Moments after being bitten, the man feels a live fire germinating in the wound as if red hot tongs contorted his flesh; that which was mortified enlarges to monstrosity, and lividness invades him. The unfortunate victim witnesses his body becoming corpse piece by piece; a chill of death invades all his being, and soon bloody threads fall from his gums; and his eyes, without intending to, will also cry blood, until, beaten by suffering and anguish, he loses the sense of reality. If we then ask the unlucky man something, he may see us through blurred eyes, but we get no response; and perhaps a final sweat of red pearls or a mouthful of blackish blood warns of impending” (This is an introduction of a book written in 1931 by a Costa Rican Biologists and snakebite expert Clodomiro Picado.) INTRODUCTION Human fear of snakes is caused almost entirely by those species that can deliver a venomous bite. It is somewhat ironic that such a minority group, like venomous snakes has endangered the whole kingdom of snakes. Let us start by correcting a frequent misnomer. People often refer to poisonous snakes, and indeed by directory definition, this is not incorrect. But as a student of herpetology we should be more specific in our terminology.

Regarding the weak diagnostic characters differentiating P. fieldi from P. persicus and very robust characters separating P. urarachnoides from both, there may arise some uncertainty in the exact taxonomic status of P. urarachnoides and whether it should remain at the current specific level or be elevated to a distinct genus.

In Pakistan, No comprehensive phylogenetic studies have so far been undertaken to collect molecular information by deciphering the cytochrome b gene (complete or partial) for the three species of interest. Keeping in mind the significance and nuisance of these deadly vipers of Pakistan, a molecular phylogeny was elaborated by successfully translating the cytochrome b gene sequence data for the three taxa of interest. Snakes for the said studies were collected through extensive field surveys conducted in Central Punjab and Chagai Desert of Pakistan from 2004 to 2006. The genetic data obtained werefurther elucidated statistically through maximum parsimony and bootstrap analysis for knowing the probable relationships among the species of interest. A comprehensive resolution of their phylogeny should be brought about for medical reasons as these lethal vipers are significant sources of snakebite accidents in many urban and rural areas of Pakistan Key words: Cytochrome b gene, Morphological difference, Mitochondrial DNA, Phylogeny, Vipers.

  • THE PUFF ADDER (BITIS ARIETANS) J.L. CLOUDSLEY-THOMPSON Department of Biology (Medawar Building), University College, University
    British Herpetological Society Bulletin, No. 26, 1988. THE PUFF ADDER (BITIS ARIETANS) J.L. CLOUDSLEY-THOMPSON Department of Biology (Medawar Building), University College, University of London, Gower Street, London WCIE 6BT The Puff Adder (Bitis arietans) is one of the largest of the African vipers and probably the species most frequently seen by travellers in that continent. It receives its English name from the habit of inflating its body and hissing loudly when disturbed. The sound is produced both when the breath is inhaled as well as during exhalation. This behaviour is characteristic of all true vipers, but is particularly evident in the case of the Puff Adder. Unlike the Gaboon Viper (Bitis gabonica), which is a forest snake, the Puff Adder inhabits subdeserts and savannas, and is also to be found in mountainous regions. Except in rain forests, Puff Adders are widespread southward to the Cape from Morocco in the west and the Sudan in the east. They occur as near to Khartoum as Jebel Aulia. This is their northernmost limit in Sudan, but they range also into western and southern Arabia. Puff Adders may exceed 1.4m in length, and have a girth of 25cm. Although they do not attain the weight of a full-grown Gaboon Viper they are, nevertheless, formidable snakes. There may be considerable variation in the coloration of Puff Adders. In some specimens, the chevrons are sooty black and the crescents cream coloured while, in others, the chevrons are dark brown or grey and the crescents dull buff. The blotched pattern of dark chevrons separated by yellow crescents (Plate 1) is cryptic.

  • The First European Pit Viper from the Miocene of Ukraine
    The first European pit viper from the Miocene of Ukraine MARTIN NANOV Ivanov, M. 1999. The fust European pit viper from the Miocene of Ukraine. - Acta Palaeontologica Polonica 44,3,327-334. The first discoveries of European pit vipers (Crotalinae gen. et sp. indet. A and B) are re- ported from the Ukrainian Miocene (MN 9a) locality of Gritsev. Based on perfectly pre- served maxillaries, two species closely related to pit vipers of the 'Agkistrodon' complex are represented at the site. It is suggested that the European fossil representatives of the 'Agkistrodon' complex are Asiatic immigrants. Pit vipers probably never expanded into the broader areas of Europe during their geological hstory. Key words: Snakes, Crotalinae, migrations, Miocene, Ukraine. Martin Ivanov [[email protected]], Department of Geology & Palaeontology, Mu- ravian Museum, Zelny' trh 6, 659 37 Bmo, Czech Republic. Introduction Gritsev is located in the western part of Ukraine, in the Khrnelnitsk area, Shepetovski district. The locality contains karstic fillings within a limestone quarry on the right bank of the Khomora river, less than 5 km west of the village of Gritsev. The strati- graphic age of the site corresponds to the Upper Miocene (lower - 'novomoskevski' - horizon of the Middle Sarmatian, MN 9a Mammal Neogene faunal zone). This locality corresponds to the Kalfinsky Formation ('Kalfinsky faunistic complex') and to the Gritsev layers ('Gritsev faunistic complex'). Fossil reptiles from Gritsev have already been investigated. Thus far, Agarnidae, Gekkonidae, Lacertidae, Anguidae, Scincidae, ?Amphisbaenia, Boidae (subfamily Erycinae), Colubridae, Elapidae and Viperidae have been reported (Lungu et al. 1989; Szyndlar & Zerova 1990; Zerova 1987, ,1989, 1992).

ABSTRACT The Gaboon Viper Bitis gabonica (Duméril, Bibron and Duméril, 1854) as a species complex has had a fairly stable taxonomic history since being described at the species level, although the species as generally recognized was transferred to the genus Bitis Gray, 1842 shortly after the original description. Likewise for the Nose-horned Viper species complex Bitis (Macrocerastes) nasicornis (Shaw, 1802). The species known as the Rhinoceros Viper Bitis rhinoceros (Schlegel, 1855) was synonymised with Bitis gabonica by virtually all herpetologists beyond 1855 until 1999 (see McDiarmid et al. 1999), when Lenk et al. (1999) provided a molecular basis to recognize the western population, (then known as Bitis gabonica rhinoceros) identified in 1999 on the basis of allopatric distribution as opposed to any consistent morphological divergence. Chippaux (2006), showed that consistent differences in the markings on the side of the head could be used to identify and separate Bitis rhinoceros from the nominate species. Meanwhile the Gaboon Viper as popularly recognized since 1999 comprises the main population centred on the wetter parts of west-central Africa (the type locality Gabon) including several countries and then three quite distant and unconnected outlier populations.
