Pedal laceration is a type of fragmentation (asexual reproduction) exhibited in sea anemones. [1]
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. It is a cluster of identical cells (clones) on the surface of a solid medium, usually derived from a single parent cell, as in bacterial colony. In contrast, solitary organisms are ones in which all individuals live independently and have all of the functions needed to survive and reproduce.
Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton. The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc with a central mouth surrounded by tentacles. Sea anemones are mostly solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies are strengthened by calcium carbonate and other materials and take various massive, plate-like, bushy or leafy forms.
The Venus flytrap sea anemone is a large sea anemone that superficially resembles a Venus flytrap. It closes its tentacles to capture prey or to protect itself. It is a deep ocean species.
Sea anemones are a group of predatory marine animals of the order Actiniaria. Because of their colourful appearance, they are named after the anemone, a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle.
Condylactis gigantea is a tropical species of ball anemone that is found in shallow reefs and other shallow inshore areas in the Caribbean Sea – more specifically the West Indies – and the western Atlantic Ocean including southern Florida through the Florida Keys. It is also commonly known as: giant Caribbean sea anemone, giant golden anemone, condylactis anemone, Haitian anemone, pink-tipped anemone, purple-tipped anemone, and Florida condy. This species can easily be seen growing in lagoons or in inner reefs as either individuals or loose groups, but never as colonies. They are often used as a model organism along with others in their genus for facultative symbiosis with monocellular algae.
The pedal disc is the surface opposite to the mouth of the sea anemone. IIt serves to attach the anemone to the substrate, or hard surface, upon which it lives.
Sagartia elegans, the elegant anemone, is a species of sea anemone in the family Sagartiidae. It is found in coastal areas of northwest Europe at depths down to 50 metres.
Bartholomea annulata is a species of sea anemone in the family Aiptasiidae, commonly known as the ringed anemone or corkscrew anemone. It is one of the most common anemones found on reefs in the Caribbean Sea.
Phlyctenactis tuberculosa, common name the wandering sea anemone or swimming anemone, is a species of sea anemone in the family Actiniidae. It is native to shallow seas around Australia and New Zealand. It was first described by the French zoologist Jean René Constant Quoy and the French naturalist Joseph Paul Gaimard. They were naval surgeons serving in the French Navy and made extensive collections of organisms they came across in their travels.
Phlyctenanthus australis, commonly known as red anemone and southern anemone, is a species of sea anemone in the family Actiniidae. It grows to a maximum size of 10 cm in diameter. The column is red-brown in colour with blue vesicles covering it. The tentacles are reddish-brown and short, and number up to around 100. This species is found in south Australia, New South Wales, down to Tasmania. This species lives on exposed reefs at depths of between 1 and 35 metres.
Amphianthus dohrnii, the sea fan anemone, is a species of sea anemone in the family Hormathiidae. It occurs in the northeastern Atlantic Ocean and Mediterranean Sea and grows on sea fans.
Aiptasia diaphana, commonly known as the yellow aiptasia or glasrose, is a species of sea anemone native to shallow waters in the temperate eastern Atlantic Ocean and the Mediterranean Sea. It has been introduced into the Red Sea.
The Enthemonae is a suborder of sea anemones in the order Actiniaria. It comprises those sea anemones with typical arrangement of mesenteries for actiniarians.
Cerianthus membranaceus, the cylinder anemone or coloured tube anemone, is a species of large, tube-dwelling anemone in the family Cerianthidae. It is native to the Mediterranean Sea and adjoining parts of the northeastern Atlantic Ocean.
Diadumene cincta is a small and delicate, usually orange, sea anemone. It has a smooth slender column and up to 200 long tentacles, and normally grows to a length of up to 35 mm (1.4 in), with a base of 10 mm (0.4 in), but specimens twice this size have been recorded. Diadumene cincta is found in the northeastern Atlantic Ocean.
Anthopleura stellula is a species of sea anemone in the family Actiniidae. It is found in the Indian Ocean and the Red Sea, and is unusual among sea anemones in that it can divide itself in two transversely.
Actinostola callosa is a species of sea anemones in the family Actinostolidae in the order Actiniaria. It is a deep sea species and occurs in both Pacific and Atlantic Oceans from the continental shelf to abyssal depths.
Gonactinia is a monotypic genus of sea anemones, and G. prolifera is the only species in the genus. It is sometimes called the storey anemone and is found on either side of the northern Atlantic Ocean.
Haloclava producta is a species of sea anemone in the family Haloclavidae, commonly known as the ghost anemone. This species is native to shallow water in the northwestern Atlantic Ocean, between Cape Hatteras and the Bay of Fundy, where it makes a temporary burrow in soft sediment. It is found on sand flats, both intertidally and subtidally.
Paranthus rapiformis, the onion anemone, is a species of sea anemone in the family Actinostolidae. It was first described by the French naturalist Charles Alexandre Lesueur in 1817 and is native to the northwestern Atlantic Ocean and the Gulf of Mexico.
