Question

Are crabs osmoregulators?

Answer 1

Crabs:

1. Crabs are crustaceans that belong to the phylum Arthropoda.
2. They are characterized by the presence of a chitinous exoskeleton and joint appendages.
3. Osmoregulators are organisms that maintain internal water and salt balance (osmotic balance) actively irrespective of the external environment.
4. Crabs are not osmoregulators. They maintain a similar osmotic balance with their surrounding environment; hence they are known as osmoconformers.
