General Considerations • Habitat • Food • Regulation
Vivarium • sand or soil • water – think fish • dechlorinate • filter • temperature • shelter
REPTILES • chelonians • lizards • snakes • tuataras • crocodiles • amphisbaenians – worm lizards
Chelonians • turtles • tortoises • terrapins
TURTLES • spend most or all of their time in water • leatherback turtle – Dermochelys coriacea • largest turtle, endangered
TORTOISE • spend most or all of their time on land • Aldabra tortoise – Geochelone gigantia • 2nd largest tortoise, CITES protected
TERRAPINS • spend significant time on land and in water
TERRAPINS - Red-Eared Slider • Southern U.S. • omnivorous • 75° F Red-Eared slider – Trachemys scripta elegans
LIZARDS • habitats - desert to marshes • diets - herbivorous, omnivorous, carnivorous, insectivorous • temperature requirements - widely varied • bottom line - do your homework
horned toad (a lizard - really!) Phrynosoma platyrhinos –
SNAKES • habitats - desert to marshes • diets - herbivorous, omnivorous, carnivorous, insectivorous • temperature requirements - widely varied • bottom line - do your homework
SNAKES - smooth green snake • habitat - open areas • diet - insectivorous • non venomous • bright green • yellow or cream belly smooth green snake – Opheodrys vernalis
SNAKES - sand boas • many species • habitat - sandy, semi-arid (for many) • diet - small rodents • non venomous • brown patterns • some have orange • females- 18 inches, 200 gm • males - 15 inches, 70 gm Desert Sand Boa – Eryx miliaris
SNAKE CARE • Research - different snakes have different needs • Vet - find one experienced with snakes • Housing • tight cage • as long as the snake • reduces lung infections
SNAKE CARE • Substrate • sand • wood chips - NOT cedar • absorbent • Water • bowl sunk into substrate • needed for shedding • much of requirement comes from prey
SNAKE CARE • heat • lamp or ceramic heater • gradient 80-95° F • don’t use hot rocks • Accessories • tree branches for climbing snakes • hiding places - flower pots, plantings
SNAKE CARE • activity • diurnal • nocturnal • other • quarantine • food - mice, weekly, diameter of snake
SNAKE CARE • handling • hook - best • tong - harmful to snake • sack • exit can - for dumping snake from sack
SNAKE CARE • temperament • always bad • never bad • inbetween • more anxious when shedding and feeding • other characteristics • musky • constrictors
SNAKE CARE • public health • venomous snakes -don’t • cage must be locked • responsible for bites • Salmonella
SNAKE CARE • breeding • live bearers - boa constrictors, water and garter snakes, and rattlesnakes • & egg layers • cool down - may require several months • incubation • 78-84 ° F • ~ 2 months
SNAKE CARE • sexing • size of snake • length of tail from cloaca • hemipenis • “cloacal pop”
SNAKE CARE • sexing • “cloacal pop”
SNAKE CARE • sexing - copperhead hemipenes
SNAKE CARE • sexing by probing
SNAKE CARE • sexing by probing male female
TUATARAS • habitat - small islands around New Zealand • diet - carnivorous • temperature • ~54° F • 50-80 cm; up to 1 kg • living fossils
AMPHISBAENIANS – worm lizards • Florida worm lizard – Rhineura floridana
