Are starfish planktonic, nektonic, or benthomic?

Question

Anyone? ^^

Thanks! ^^

Answer 1

Sea stars or starfish are marine invertebrates belonging to phylum Echinodermata, class Asteroidea. The names sea star and starfish are also used for the closely related brittle stars, which make up the class Ophiuroidea. They exhibit a superficially radial symmetry. Starfish typically have five or more "arms" which radiate from an indistinct disk (pentaradial symmetry). In fact, their evolutionary ancestors are believed to have had bilateral symmetry, and sea stars do exhibit some superficial remnant of this body structure.

Sea stars do not have movable skeletons, but instead possess a hydraulic water vascular system. The water vascular system has many projections called tube feet, located on the ventral face of the sea star's arms, which function in locomotion and aid with feeding.

As these creatures are echinoderms and not actually fish, most marine biologists prefer to replace the term starfish with the less misleading term sea star.

Answer 2

Benthonic. Technically its meroplanktonic: planktonic during it's tiny larval stage then it settles on the bottom and is benthonic for the rest of its life.

Answer 3

Starfish live on the seafloor. Things that live on the seafloor are called benthos. So I think starfish are benthonic.

Answer 4

planktonic
