The carpet flatworm (Thysanozoon brocchii) is a polyclad flatworm in the family Pseudocerotidae. [1]
Carpet flatworms may grow to 8 cm in total length. They have pale bodies with pinkish frilled margins. The upper surface of the animal is covered with short finger-like papillae (protrusions) in pinks, caramels and browns. There is a smale pale protruding fold at the head. [2]
Carpet flatworms are found off the South African coast from the Cape Peninsula to Port Elizabeth as well as in the Mediterranean and the Red Sea. They are seen subtidally and down to at least 35m underwater. [2]
These animals use undulations of their body margins to swim. Their dorsal protrusions aid in oxygen uptake and improve camouflage. [2]
According to the World Register of Marine Species, the following species are synonyms of Thysanozoon brocchii: [1]
Nereis is a genus of polychaete worms in the family Nereididae. It comprises many species, most of which are marine. Nereis possess setae and parapodia for locomotion and gas exchange. They may have two types of setae, which are found on the parapodia. Acicular setae provide support. Locomotor setae are for crawling, and are the bristles that are visible on the exterior of the Polychaeta. They are cylindrical in shape, found not only in sandy areas, and they are adapted to burrow. They often cling to seagrass (posidonia) or other grass on rocks and sometimes gather in large groups.
Bulla is a genus of medium to large hermaphrodite sea snails, shelled marine opisthobranch gastropod molluscs. These herbivorous snails are in the suborder Cephalaspidea, headshield slugs, and the order Opisthobranchia.
Planaria is a genus of planarians in the family Planariidae. Due to its excellent ability to regenerate, species of Planaria has also been used as model organisms in regeneration studies. When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual. When decapitated, they retain their memories.
Octopus is the largest genus of octopuses, comprising about 100 species. These species are widespread throughout the world's oceans. Many species formerly placed in the genus Octopus are now assigned to other genera within the family. The octopus has 8 arms, averaging 20 cm (8 in) long for an adult.
Trochus is a genus of medium-to large-sized, top-shaped sea snails with an operculum, of the family Trochidae, the top snails.
Paludinella is a genus of minute salt marsh snails with an operculum, aquatic gastropod mollusks or micromollusks, in the family Assimineidae.
The Pleurobranchidae are a taxonomic family of sea slugs, marine gastropod molluscs in the clade Pleurobranchomorpha.
Eunice is a genus in the polychaete family Eunicidae. Individuals grow to a length of between 0.5 and 300 cm. Their bodies have multiple segments. They have two eyes and five tentacles. They have well-developed sense organs and relatively large brains. Their color is dark purple-brown to red-brown with a white ring at the fourth segment. They are found in oceans and seas around the world. They have an evertible proboscis with distinctive mouthparts, some of which comprise two rows of maxilliary plates in a radula-like fashion.
Tritonia is a genus of sea slugs, nudibranchs, shell-less marine gastropod molluscs in the family Tritoniidae.
Doris is a genus of sea slugs, specifically dorid nudibranchs. These animals are marine gastropod molluscs in the family Dorididae.
Euspira is a genus of medium-sized sea snails, marine gastropod molluscs in the subfamily Polinicinae of the family Naticidae, the moon snails.
Euspira nitida, the common necklace shell, is a species of sea snail, a marine gastropod mollusc in the family Naticidae, the moon snails.
Marionia is a genus of sea slugs, specifically dendronotid nudibranchs, marine gastropod molluscs in the family Tritoniidae.
Raphitoma is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.
Jujubinus exasperatus, the Rough Top Shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.
Lysidice is a genus of polychaete worms in the family Eunicidae.
Cerebratulus is a genus of nemerteans belonging to the family Lineidae.
