description Thalassocalyce inconstans Overview
Thalassocalyce inconstans is a species of deep-sea comb jelly classified within the phylum Ctenophora. It is the sole recognized member of the order Thalassocalycida, noted for its bell-shaped, medusa-like physical appearance that distinguishes it from other ctenophores. The species was first scientifically described by researchers Laurence Madin and Grace Harbison in 1978. It is of primary interest to marine biologists studying deep-sea invertebrate diversity.
help Thalassocalyce inconstans FAQ
Is Thalassocalyce inconstans a true jellyfish?
No. Thalassocalyce inconstans is a comb jelly in the phylum Ctenophora, not a scyphozoan jellyfish, even though its bell-shaped body resembles a medusa.
What makes Thalassocalyce inconstans unusual among comb jellies?
Its large, medusa-like bell and broad oral structures give it an appearance unlike the familiar oval or ribbon-shaped ctenophores. It is also the sole recognized species in the order Thalassocalycida.
Where does Thalassocalyce inconstans live?
It is a deep-sea ctenophore associated with open ocean waters far below the surface. That habitat makes it difficult to observe and means that many images come from submersible or remotely operated vehicle work.
How does Thalassocalyce inconstans move?
Like other ctenophores, it moves primarily with rows of beating ciliary plates called comb rows. Its gelatinous bell and oral lobes also help it capture small drifting prey in the water column.
