Why are humans amphibians according to Screwtape?
Lewis was using a metaphor. In a sense, Humans are half creatures of earth, half creatures of heaven, made to transition from the former to the latter. Like as a frog starts as a tadpole (in water, gilled) but transforms into the fully legged tail-less adult creature.
No, absolutely not. They are totally different. Mammals have fur or hair ambhibians do not. Mammals give birth except for the Platypus & Echidna, and amphibians lay eggs
They obtain oxygen from water through gills (during at least part of their life cycle).
Occasionally, yes. They'll more or less go after young fawns, but they also won't hesitate going after does or older, weaker bucks and does. Bears mainly prefer to hunt other animals when other food items, like plants, berries and grubs are not plentiful or available.

How many amphibians are there in the world?
Well, I believe there are 5 main types, which are: Frogs, Salamanders, Newts, Toads, and Caecilians. I think this is right.. You can find more on Google. As for in the world, I don't know how many amphibians there are if you're asking for an exact answer.
Hope this helped =)
Isn't a toad pretty much a frog?
What makes an amphibian an ectoderm?
I can only assume that you mean ectotherm and not ectoderm.
Ectoderm is the outer germ layer of an embryo.... so this wouldn't make sense.
An ectotherm is a cold-blooded animal (e.g. amphibians). The animal depends on external sources to regulate its body temperature.
This is opposed to an endotherm, which is warm-blooded (e.g. mammals, birds...). They regulate their temperature themselves, creating most of their heat through metabolic processes.
Do axolotl parents take care of their eggs?
No, after about a month and a half they leave their children and let them go.
What are skin flaps on a amphibian?
Skin flaps in amphibians are extensions of the skin that can serve various functions, including respiration, thermoregulation, and camouflage. These flaps can increase the surface area for gas exchange, allowing certain species to absorb oxygen more efficiently through their skin. In some cases, skin flaps may also aid in displaying colors or patterns that help with mating or deterring predators. Overall, they are adaptations that enhance the amphibian's survival in diverse environments.
