Question

Are blue crabs osmoregulatory?

Answer 1

Osmoregulation:

1. The management of water and salt concentrations to maintain consistent osmotic pressure in an organism's fluids is called osmoregulation.
2. An organism that maintains an internal balance between water and dissolved materials is called an osmoregulator.

Blue crabs:

1. Some brachyuran crabs (such as the blue crab Callinectes sapidus) can regulate their osmoregulation and thrive in freshwater.
2. Osmoregulation relies heavily on ion transporters and channels.
3. Blue crabs are distinguished from other crabs by their swim fins.
