Organisms
A biologist isolates an organism from a pond and describes it in his lab notebook as having both a larval and an adult stage, air-breathing lungs, the digestive system of a carnivore, eggs that lack shells, and camouflage epidermis that secretes toxins, and as exhibiting external fertilization. What is the organism being described?
I am hesitating on the following:
- A snake
- A frog
- A freshwater clam
- A salamander
- A lungfish
Thanks in advance for your much needed help!

How can it be clam when it has air-breathing lungs?! It is frog or/and salamandra. There are no difference between them in these shown characteristics except maybe for camouflaged skin which is more common in frogs although some salamanders can have it too (although thay usualy have aposematic colored skin). So I say it is most definatly FROG!
