1. Identify this organism down to the nearest taxon required by the list.
2. What must occur for courtship in this taxon to begin?
3. Does this taxon exhibit temperature-dependent sex determination? If so, which temperatures create males and which create females?
4. Describe an egg created by a female of this taxon.

1. Genus Trachemys
2. The male swims around the female and flutters or vibrates the back side of his long claws on and around her face and head (possibly to direct pheromones towards her). The female swims toward the male and (if she is receptive) sinks to the bottom for mating.
3. Yes: 22-27 degrees C is male, and warmer is female.
4. Round-ish, white, small, holds around half turtle and half egg sac right before hatching, hatches within 59-112 days.

It's actually Chrysemys, but I'm going to assume all the other information is accurate for Trachemys (I couldn't find a lot to put in my binder...) Your turn, though.

1) Identify organism 1.
2) Identify organism 2.
3) List two similarities between them.
4) List two differences between them.
5) Around how many costal grooves do organisms of the same taxon as organism 1 have?
6) What are two known predators (of any species) of the genus to which organism 2 belongs?

here goes! I'm quite new to this event, kindly bear with me :,)
1. Amphiuma?
2. Siren
3. Both demonstrate sexual dimorphism and inhabit the southeastern US.
4. Amphiumas lose their gills upon reaching sexual maturity while sirens retain their gills throughout their lives. Sirens have functional limbs while the limbs of amphiumas are purely vestigial.
5. Around 55-60.
6. Red-bellied mud snakes and American alligators.
1. Identify the organism in this picture.
2. One species in this genus is described to be a ring species. What does this mean?
3. What is unique about the tail of this organism? What does this help it do?
4. What is the purpose of the nasolabial groove present in this organism?

okay so i dont have my binder with me so im doing this off of memory
1. Ensatina (i think?)
2. okay so a ring species is when you have a few species that cannot interbreed but they’re living in the same region, which leads to a ring of populations that can interbreed
3. their tails are really toxic, leading to them not being preyed on. they can also regrow
4. they absorb fluids and help the ensatina detect/sense?

Yeah, looks right. 4 is more specific than what I was looking for (chemoreception) but your answer is good. Go ahead.

Alright.
1) Is this specimen poisonous?
2) What is the saying that specifies how to tell if it is a poisonous snake?
3) What does the venom do?
4) How can you cure/stop the effects of the venom?
