Peltodoris atromaculata, more commonly known as the dotted sea slug or sea cow, is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Discodorididae. [1] It dwells in salt water up to the depth of 40m. It is exclusively found in precorralligene and coralligene communities and is very common in such communities. [2]
The name "sea slug" is often applied to nudibranchs and a paraphyletic set of other marine gastropods without apparent shells. [2] Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species imply that these animals are under constant threat of predators ...
Navanax inermis, common name the California aglaja, is a large species of predatory sea slug, a marine opisthobranch gastropod mollusk in the family Aglajidae. Navanax is not a nudibranch, even though it somewhat resembles one; it belongs to a more ancient lineage of opisthobranchs called the cephalaspideans or head shield slugs and snails.
Although these sea slugs live on the open ocean, they sometimes accidentally wash up onto the shore, so they may be found on beaches. [10] In April 2022, specimens were found in the Gulf of Mexico along the Texas coast. [19] On August 31, 2023, blue sea slugs were reported to be found along Karon Beach, Phuket, Thailand. [20] [21]
Umbraculum umbraculum, common name the umbrella slug, is a species of large sea snail or limpet, a marine gastropod mollusc in the family Umbraculidae. [2] It is found in tropical to warm temperate parts of the Indo-Pacific and Atlantic Oceans, where it feeds on sponges .
Sacoglossa are a superorder of small sea slugs and sea snails, marine gastropod mollusks that belong to the clade Heterobranchia known as sacoglossans. There are 284 valid species recognized within this superorder. [3] Sacoglossans live by ingesting the cellular contents of algae, hence they are sometimes called "sap-sucking sea slugs". [4]
When the slug is as big as the meduse, it starts to swim, eating the remaining parts, including the tentacles. [ 3 ] In adulthood its diet is no longer restricted to Zanclea , although observations of feeding behaviour are sparse.
Glaucus is a genus of small blue pelagic sea slugs.They are aeolid nudibranchs, [1] ranging in size from 20 to 40 mm (0.79 to 1.57 in). [2] They feed on colonial cnidarians such as Portuguese man o' wars, blue buttons, and purple sails.
