| Elysia grandifolia Kelaart,1858 | |
Elysia grandifolia is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae native to the waters off southern India and Sri Lanka. It has colonised the waters of the eastern Mediterranean Sea.
Edward Frederick Kelaart described the species in 1858 as Elysia grandifolia. He was unsure of its placement within the genus, and considered the new genus name Hydropsyche as an alternative. Kelaart was a military surgeon who became interested in marine life after seeing an aquarium in London, and set about describing nudibranchs off the waters of Ceylon (Sri Lanka), where he was stationed. [1] [2]
Sometimes reaching 12 cm (4.8 in) long, [3] Elysia grandifolia has a light green head and body, marked with white and more rarely black spots. The head and neck are bare, apart from bearing two tentacles folded along the sides of the head. The body is wider at the front and tapers to a point at the rear, and lacks a distinct foot. The mouth lies underneath. Running along the length of the body on each side is a veiny green wing-like membrane—known as a parapodium—with black and gold margin. Laterally it can measure 6.35 cm (2.5 in) across with wings expanded. Kelaart wrote, "The whole animal gives one the idea of a large leaf and, when moving, that of a butterfly.", adding that the pulsating heart was visible in the middle of its back. [1]
This marine species is found on seaweed in the waters off Sri Lanka and southern India. [3] It is an introduced species in the eastern basin of the Mediterranean Sea, where it has been recorded off the coast of Turkey and Israel. [4]
Rhinophis oxyrhynchus, also known as Schneider's earth snake or Schneider's shieldtail, is a species of uropeltid snake endemic to Sri Lanka.
Lieutenant Colonel Edward Frederick Kelaart was a Ceylonese-born physician and naturalist. He made some of the first systematic studies from the region and described many plants and animals from Sri Lanka.
Elysia viridis, the sap-sucking slug, is a small-to-medium-sized species of green sea slug, a marine opisthobranch gastropod mollusc in the family Plakobranchidae.
Elysia is a genus of sea slugs, marine gastropod molluscs in the family Plakobranchidae. These animals are colorful sea slugs, and they can superficially resemble nudibranchs, but are not very closely related to them. Instead they are sacoglossans, commonly known as sap-sucking slugs.
Goniobranchus preciosus is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
Jorunna funebris, commonly called the dotted nudibranch, is a large species of sea slug. It is a dorid nudibranch, meaning it is a shell-less marine gastropod mollusc in the family Discodorididae. The genus Jorunna is composed of roughly 15 other species of nudibranchs, which feed on a variety of sponges.
Polybranchia orientalis is a species of sacoglossan sea slug, a shell-less marine opisthobranch gastropod mollusk in the family Caliphyllidae.
Taringa sublutea is a species of sea slug, a dorid nudibranch, shell-less marine gastropod mollusks in the family Discodorididae.
Goniobranchus gleniei is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
Goniobranchus fidelis, also commonly known as the faithful sea slug, is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
Elysia gordanae is a species of sea slug, a marine gastropod mollusc.
Elysia diomedea is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae.
Elysia trisinuata is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae. This sea slug resembles a nudibranch but is not closely related to that order of gastropods, instead belonging to another clade, Sacoglossa, the "sap-sucking" sea slugs.
Elysia serca, the seagrass elysia or Caribbean seagrass elysia, is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae. Although this sea slug resembles a nudibranch, it is not a nudibranch; it belongs to the clade, Sacoglossa, the "sap-sucking" sea slugs. It was first described by Marcus in 1955 from specimens found in Brazil.
Atagema osseosa is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Discodorididae.
Atagema spongiosa is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Discodorididae.
Samla bicolor is a species of sea slug, an aeolid nudibranch, a marine heterobranch mollusc in the family Samlidae.
Phyllidiella zeylanica is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Phyllidiidae.
Platydoris striata is a species of sea slug, a dorid nudibranch, shell-less marine opisthobranch gastropod mollusks in the family Discodorididae.
