WHERE DO SAWFISH LIVE? Educator Information for Student Activity 4
WHERE DO SAWFISH LIVE? Educator Information For Student Activity 4 Lesson Summary: This lesson examines the diversity of locations and habitats where sawfish are found throughout the world. Vocabulary: Distribution, habitats Background Information: There are six recognized species of sawfish throughout the world. In this activity the distribution range of each species will be discussed and mapped. Information on each species can be found in the “Sawfish In Peril” teaching binder within each of the species profiles. Materials: Copies of activity map sheets and species profile laminated cards w/maps Pencils: colored pencils recommended Procedure: This activity begins by getting students to look at the different maps of sawfish species distribution. Have each student color in a map template of the distribution of a favorite sawfish species or have students form groups to color the maps for each species. Discussion Questions: Where do sawfish live? What habitats do sawfish reside in? Where would you go if you wanted to see a sawfish? Extension Activities: For more advanced students, the following questions can be discussed: What determines where sawfish species live? Do sawfish prefer certain water temperatures and habitat types? In the past, did sawfish have larger distribution then they do currently? If so, why do you think that is? www.flmnh.ufl.edu/fish 6-14 © 2010 Florida Museum of Natural History WHERE DO SAWFISH LIVE?

Life History of the Critically Endangered Largetooth Sawfish: a Compilation of Data for Population Assessment and Demographic Modelling

The species is now extinct or severely depleted in many former parts of its range and is protected in some other range states where populations persist. The likelihood of collecting substantial new biological information is now low. Here, we review all available life history infor- mation on size, age and growth, reproductive biology, and demography as a resource for popula- tion assessment and demographic modelling. We also revisit a subset of historical data from the 1970s to examine the maternal size−litter size relationship. All available information on life history is derived from the Indo-West Pacific (i.e. northern Australia) and the Western Atlantic (i.e. Lake Nicaragua-Río San Juan system in Central America) subpopulations. P. pristis reaches a maxi- mum size of at least 705 cm total length (TL), size-at-birth is 72−90 cm TL, female size-at-maturity is reached by 300 cm TL, male size-at-maturity is 280−300 cm TL, age-at-maturity is 8−10 yr, longevity is 30−36 yr, litter size range is 1−20 (mean of 7.3 in Lake Nicaragua), and reproductive periodicity is suspected to be biennial in Lake Nicaragua (Western Atlantic) but annual in Aus- tralia (Indo-West Pacific). -
A New Stingray from South Africa
Nature Vol. 289 22 January 1981 221 A new stingray from South Africa from Alwyne Wheeler ICHTHYOLOGISTS are accustomed to the regular description of previously un recognized species of fishes, which if not a daily event at least happens so frequently as not to cause great comment. Previously undescribed genera are like wise not infrequently published, but higher categories are increasingly less common. The discovery of a new stingray, which is so different from all known rays as to require both a new family and a new suborder to accommodate its distinctive characters, is therefore a remarkable event. A recent paper by P.e. Heemstra and M.M. Smith (Ichthyological Bulletin oj the J. L.B. Smith Institute of Ichthyology 43, I; 1980) describes this most striking ray as Hexatrygon bickelli and discusses its differences from other batoid fishes. Surprisingly, this remarkable fish was not the result of some organized deep-sea fishing programme, but was found lying on the beach at Port Elizabeth. It was fresh but had suffered some loss of skin by sand abrasion on the beach, and the margins of its fins appeared desiccated in places. The way it was discovered leaves a tantalising question as to its normal habitat, but Heemstra and Smith suggest that it may live in moderately deep water of 400-1,000m. This suggestion is Ventral view of Hexatrygon bickelli supported by its general appearance (small eyes, thin black dorsal skin, f1acid an acellular jelly, while the underside is chimaeroids Rhinochimaera and snout) and the chemistry of its liver-oil. richly supplied with well developed Harriota, and there can be little doubt The classification of Hexatrygon ampullae of Lorenzini. -

VARGAS-NALVARTEb a Áreas Costeras y Recursos Marinos (ACOREMA), Pisco, Peru b Museo de Sitio Huaca Pucllana, Calle General Borgoño cuadra 8 S/N, Lima 18, Peru ABSTRACT New data regarding the white shark (Carcharodon carcharias) at the archaeological complex Huaca Pucllana (200–700 AD) are presented on the basis of the recent discovery of teeth in ritual offering features. Previous information of this species from fossil, archaeological and modern records is reviewed. The use of the white sharks as an El Niño indicator is rejected. Past and present white shark distribution in the South East Pacificis reviewed, and the extermination of pinniped colonies as a factor in the poor modern record is discussed.

A Life History Overview of the Largetooth Sawfish Pristis Pristis
LIFE HISTORY OVERVIEW No. 1 A Life History Overview of the Largetooth Sawfish Pristis pristis 2013 Prepared by Peter M. Kyne & Pierre Feutry NERP Marine Biodiversity Hub Project 2.4 (Supporting Management of Listed and Rare Species) Research Institute for the Environment and Livelihoods Charles Darwin University Darwin NT 0909, Australia Email: [email protected] Introduction The Largetooth Sawfish Pristis pristis is wide-ranging in tropical waters with distinct geographically-separated populations in the Western Atlantic, Eastern Atlantic, Eastern Pacific and Indo-West Pacific. It was until recently referred to as P. microdon (Freshwater Sawfish) in the Indo-West Pacific and P. perotteti in the Atlantic before research showed these to be synonymous with P. pristis (Faria et al. 2013). Northern Australia represents one of the last strongholds of a species not only once widespread in the Indo-West Pacific, but widespread in many tropical waters. Here, the available life history information on the Largetooth Sawfish is compiled and summarised. Much of this was published under the previous names P. microdon and P. perotteti. The species’ life history is characterised by parameters such as late age at maturity, long lifespan and low fecundity, which results in a low intrinsic rate of population increase (Simpfendorfer 2000; Moreno Iturria 2012). This life history is generally consistent with that of many large elasmobranchs (sharks and rays). For such a wide-ranging and conspicuous species, life history is poorly understood and available information is patchy. For example, the only dedicated reproductive studies were undertaken in the Lake Nicaragua-Río San Juan system in Central America (hereafter referred to as ‘Lake Nicaragua’) (Thorson 1976, 1982), and the vast majority of life history information originates from either Lake Nicaragua or northern Australia (northwest Western Australia and the Queensland Gulf of Carpentaria) (e.g. -

The emphasis has been on fishes generally but these studies have also contributed greatly to our knowledge of chondrichthyans in the region, as well as across the broader Indo–West Pacific. An annotated checklist of cartilaginous fishes of the Philippines is compiled based on historical information and new data. A Taiwanese deepwater trawl survey off Luzon in 1995 produced specimens of 15 species including 12 new records for the Philippines and a few species new to science.
