  • Scale Sensillae of the File Snake (Serpentes: Acrochordidae) and Some Other Aquatic and Burrowing Snakes
    SCALE SENSILLAE OF THE FILE SNAKE (SERPENTES: ACROCHORDIDAE) AND SOME OTHER AQUATIC AND BURROWING SNAKES by DAVID POVEL and JEROEN VAN DER KOOIJ (Section Dynamic Morphology,Institute of Evolutionaryand Ecological Sciences, Leiden University,P.O. Box 9516, 2300 RA Leiden, The Netherlands) ABSTRACT The acrochordid snakes are aquatic, living in environmentswith often a poor visibility. It therefore was investigatedhow these animals detect their prey. Two earlier studies of their scales revealed a rather complex scale organ, composedof hairlike protrusions and plate-like structures. However, no satisfactory explanation was given for the structures found, e.g., an undefined sensilla or a gland. Skin samples from various sites of the body of Acrochordus granulatus and A. javanicus were studied. Scanning electron microscopic pictures revealed that each scale of the head contains up to seven sensillae, and each of the keeled scales of the rest of the body has one. Also a modified Allochrome staining procedure on tissue samples was performed to detect glycogen, which is known to occur in discoidal nerve endings of tactile sense organs of reptiles. Light microscopicslides revealedglycogen particles in a small pillow-shaped area just below the hairlike protrusions of an organ. Moreover, small nerves were recognized near the same location. No indications were found for the scale organs to have a glandular function. Because of the reported reactions of a snake when it is touched by a fish, these scale sensilla are proposed to be very sensitivemechanoreceptors. Comparisons were made with the scale organs of snakes from various habitats, viz. the seasnake Lapemis hardwicki, and burrowing snakes such as Xenopeltis unicolor and Cylindrophisrufus.

  • First Record of Laticauda Semifasciata (Reptilia: Squamata: Elapidae: Laticaudinae) from Korea
    Anim. Syst. Evol. Divers. Vol. 32, No. 2: 148-152, April 2016 http://dx.doi.org/10.5635/ASED.2016.32.2.148 Short communication First Record of Laticauda semifasciata (Reptilia: Squamata: Elapidae: Laticaudinae) from Korea Jaejin Park1, Il-Hun Kim1,2, Kyo-Sung Koo1, Daesik Park3,* 1Department of Biology, Kangwon National University, Chuncheon 24341, Korea 2National Marine Biodiversity Institute of Korea, Seocheon 33661, Korea 3Division of Science Education, Kangwon National University, Chuncheon 24341, Korea ABSTRACT The Chinese sea snake Laticauda semifasciata (Reinwardt in Schlegel, 1837) is newly reported from Korean waters based on three specimens collected from Jeju Island, Korea, in August, September, and November 2015. This is the first time that the genus Laticauda and subfamily Laticaudinae has been reported from Korean waters. The subfamily Laticaudinae has ventrals that are four to five times wider than the adjacent dorsals, which are unlike the ventrals that are similar or up to two times wider than adjacent dorsals in the subfamily Hydrophiinae. Laticauda semifasciata is distinct from other species because it has three prefrontals and its rostrals are horizontally divided into two. As the result of this report, four species (L. semifasciata, Hydrophis (Pelamis) platurus, Hydrophis cyanocinctus, and H. melanocephalus) of sea snakes have been reported in Korean waters. Keywords: sea snake, Hydrophiinae, Laticaudinae, Chinese sea snake, Laticauda semifasciata INTRODUCTION semifasciata (Reinwardt in Schlegel, 1837) of the genus Laticauda and subfamily Laticaudinae for the first time in Globally, 70 sea snakes (aquatic elapids) of 8 genera in the Korean waters based on the specimens collected in Jeju Is- two subfamilies Hydrophiinae and Laticaudinae have been land in 2015.

  • Snakes of the Siwalik Group (Miocene of Pakistan): Systematics and Relationship to Environmental Change
    Palaeontologia Electronica http://palaeo-electronica.org SNAKES OF THE SIWALIK GROUP (MIOCENE OF PAKISTAN): SYSTEMATICS AND RELATIONSHIP TO ENVIRONMENTAL CHANGE Jason J. Head ABSTRACT The lower and middle Siwalik Group of the Potwar Plateau, Pakistan (Miocene, approximately 18 to 3.5 Ma) is a continuous fluvial sequence that preserves a dense fossil record of snakes. The record consists of approximately 1,500 vertebrae derived from surface-collection and screen-washing of bulk matrix. This record represents 12 identifiable taxa and morphotypes, including Python sp., Acrochordus dehmi, Ganso- phis potwarensis gen. et sp. nov., Bungarus sp., Chotaophis padhriensis, gen. et sp. nov., and Sivaophis downsi gen. et sp. nov. The record is dominated by Acrochordus dehmi, a fully-aquatic taxon, but diversity increases among terrestrial and semi-aquatic taxa beginning at approximately 10 Ma, roughly coeval with proxy data indicating the inception of the Asian monsoons and increasing seasonality on the Potwar Plateau. Taxonomic differences between the Siwalik Group and coeval European faunas indi- cate that South Asia was a distinct biogeographic theater from Europe by the middle Miocene. Differences between the Siwalik Group and extant snake faunas indicate sig- nificant environmental changes on the Plateau after the last fossil snake occurrences in the Siwalik section. Jason J.

Some exotic animals have also become a problem for resource managers. The rapid and effective dispersal characteristics of these invaders make them extremely difficult to eliminate. This workshop will describe some of the more common and troublesome aquatic invasive exotic species in central Florida, current methods being used to manage them and opportunities to partner and get assistance.
