How many knees does a tarantula have?

Answer 1

Tarantulas have eight legs, and each leg has seven segments, including a joint that functions similarly to a knee. However, they do not have knees in the same way vertebrates do; their leg joints allow for movement but are not anatomically identical to mammalian knees. Therefore, while they have joints that serve a similar purpose, it is not accurate to count them as traditional knees.
