Elysia chlorotica (common name the eastern emerald elysia) is a small-to-medium-sized species of green sea slug, a marine opisthobranch gastropod mollusc. This sea slug superficially resembles a nudibranch, yet it does not belong to that clade. Instead it is a member of the clade Sacoglossa, the sap-sucking sea slugs.
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods , i.e. they are sea snails (marine gastropod mollusks ) that, over evolutionary time, have either entirely lost their shells or have seemingly lost their shells due to having a ...
In addition to trapping prey, the slug's hood can snap shut and propel the animal away from danger. Predators might overlook the sea slug's transparent body or be startled by its bioluminescence ...
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]
Heads of some sea slugs can pull themselves free from their bodies and move around while growing a new body, according to a study by ecologists from Nara Women’s University in Japan.Researchers ...
Elysia sea slugs graze on algae and some species such as E. viridis and E. chlorotica hijack the chloroplasts for themselves. The chloroplasts end up lining the slug's digestive tract, enabling the slugs to survive solely by photosynthesis for several months at a time.This association is crucial for the development and maturing of the slug.
Costasiella kuroshimae is a species of sacoglossan sea slug. Costasiella kuroshimae are shell-less marine opisthobranch gastropod mollusks in the family Costasiellidae . [ 1 ] Despite being animals, they indirectly perform photosynthesis , via kleptoplasty .
Sea angels in Australian waters. These organisms have a wide geographic range, from polar regions, under sea ice, to equatorial (tropic) seas. [2] From spring to autumn, sea angels live at a depth of 200 m in the Sea of Okhotsk. In winter, they migrate to the coast of north Hokkaido with drift ice.
