Snake anatomy
***Make any group do 5 pushups
Tracheal opening (______) can extend forward during swallowing allowing snake to breath.
glottis
this enzyme causes can cause cardiovascular issues or bleeding out internally, blood cells will either overall coagulate, or thin out causing prey to bleed out(rattlesnakes, water moccasins).
Hemotoxin
other wise known as the cottonmouth -typically in water ecosystems
water moccasin
***Triple Points
Greek word for turtle, or scientific word for Green Sea Turtle
The scientific study of amphibians and reptiles.
Herpetology
the snake has poor vision and no external ears or eardrum, it also has no eyelids and protects its eyes with a transparent __________
spectacle
Affects nerves and breathing
Neurotoxin
***Double Points
Squeeze prey to death (e.g., boas, pythons, anacondas).
Constriction
_______ is an international organization that protects endangered species.
CITES
(Convention on International Trade in Endangered Species of Wild Fauna and Flora )
_________ Movement
Rectilinear
A special structure called the vomeronasal organ; detects chemical cues via tongue-flicking
Jacobson’s Organ
this toxin can serve as either a nerve signal blocker or attach to a receptor and turn it on causing violent spasms, (copperheads, cobra, black mamba).
Neurotoxin
Allows striking prey in total darkness.
Thermo Sensors, Heat Sensing
Name 2 possible methods that Green Sea Turtles use to navigate through the open ocean to find their nesting grounds.
Use Earth’s magnetic field, chemical cues, and possibly celestial navigation.
(e.g., cobra): Hypodermic-like fangs that sit on the front part of the mouth
Front-fanged
A system for detecting heat, often used by snakes to locate warm-blooded prey.
Thermo sensor
Proteins that dissolve cell membranes and digest prey before entering digestive system (rattlesnakes)
Cytotoxin :(
Most common movement (classic S-shape).
Snake presses against surfaces to propel forward
Lateral Undulation
True or False
The green sea turtle is on of the only sea turtle species that can produce its own body heat when it swims the open ocean.
FALSE!!!! Sea Turtles are cold blooded ectotherms
What species of snake did we dissect in class?
Checkered Garter
The _______ in snakes is a single opening at the base of the tail that serves as the exit for waste products, including urine and feces, as well as the reproductive system.
cloaca
Albert Calmette was the scientist who began producing this important serum that counteracts snake venom
antivenom
name 3 venomous Texas Hill Country Snakes
*** Double Points
Turtles travel 1,000s of miles for Reproduction, they return to their original nesting site where they eggs lay their eggs outside the body to develop and hatch
Oviparity
***Take AWAY 300 points from any group
Enzymes in venom that break down cell membranes, causing tissue damage.
Phospholipases:
Some snake species Reproduction occurs where eggs develop inside the female’s body, and hatch inside or immediately after laying.
Ovoviviparity
along with the forked tongue a snake uses this chemosensory organ located in the nasal cavity of most amphibians, reptiles, and some mammals
Jacobson's Organ
An animal that relies on external sources for body heat (cold-blooded).
Ectotherm
Name two things that Sea Turtles are known to eat.
sea grass, kelp, jellyfish
The order of reptiles that includes both snakes and lizards.
Squamata
