Which animal has the same adaptation as crab for breathing in water and on land?

The animal that has a similar adaptation to crabs for breathing in water and on land is the coconut crab.

Here's why:

* Crabs: Crabs use gills to breathe underwater. However, they also have a specialized adaptation called branchiostegal lungs which allows them to breathe air for short periods of time when they are out of water.

* Coconut Crabs: Like crabs, coconut crabs use gills to breathe underwater. They also have modified gills that can hold moisture and allow them to breathe air for extended periods of time.

This adaptation makes both crabs and coconut crabs highly adaptable to living in both aquatic and terrestrial environments.
