What Animals Are Osmoregulators

Osmoregulators actively control salt concentrations despite the salt concentrations in the environment. An example is freshwater fish. Some fish have evolved osmoregulatory mechanisms to survive in all kinds of aquatic environments.

What types of animals are Osmoregulators?

Most marine invertebrates such as starfish, jellyfish and lobsters are osmoconformers. Osmoregulators are organisms that actively regulate their osmotic pressure, independent of the surrounding environment. Many vertebrates, including humans, are osmoregulatory.

What animals are osmoconformers?

Most osmoconformers are marine invertebrates such as echinoderms (such as starfish), mussels, marine crabs, lobsters, jellyfish, ascidians (sea squirts – primitive chordates), and scallops. Some insects are also osmoconformers.
