Linckia is a genus of sea stars found mainly in the Indo-Pacific region. They are known to be creatures with remarkable regenerative abilities, and capable of defensive autotomy against predators. They reproduce asexually.

The genus is named after the German naturalist Johann Heinrich Linck (1674–1734).

Systematics

Five groups within Linckia have been clearly genetically differentiated - L. columbiae, L. bouvieri, two clades within L. guildingi, and one clade with two subclades consisting of both L. laevigata and L. multifora . [2] A list of species of Linckia: [1]

<span class="mw-page-title-main">Ophidiasteridae</span> Family of starfishes

The Ophidiasteridae are a family of sea stars with about 30 genera. Occurring both in the Indo-Pacific and Atlantic Oceans, ophidiasterids are greatest in diversity in the Indo-Pacific. Many of the genera in this family exhibit brilliant colors and patterns, which sometimes can be attributed to aposematism and crypsis to protect themselves from predators. Some ophidiasterids possess remarkable powers of regeneration, enabling them to either reproduce asexually or to survive serious damage made by predators or forces of nature. Some species belonging to Linckia, Ophidiaster and Phataria shed single arms that regenerate the disc and the remaining rays to form a complete individual. Some of these also reproduce asexually by parthenogenesis.

Linckia multifora is a variously colored starfish in the family Ophidiasteridae that is found in the Indian Ocean and Red Sea. Its common names include the Dalmatian Linckia, mottled Linckia, spotted Linckia, multicolor sea star and multi-pore sea star.

Asexual reproduction in starfish takes place by fission or through autotomy of arms. In fission, the central disc breaks into two pieces and each portion then regenerates the missing parts. In autotomy, an arm is shed with part of the central disc attached, which continues to live independently as a "comet", eventually growing a new set of arms. Fragmentation occurs on star fishes.

Thyca crystallina is a species of sea snail, a marine gastropod mollusc in the family Eulimidae. It is one of nine species within the genus Thyca, all of which are parasitic on starfish in the Indo-Pacific Ocean. This species was first described in 1846 by the American conchologist Augustus Addison Gould as Pileopsis crystallina but was later transferred to Thyca.

<i>Phataria unifascialis</i> Species of starfish

Phataria unifascialis is a species of starfish in the family Ophidiasteridae. It is sometimes known as the blue seastar or tan starfish, but both these names are also used for other species. It is native to the eastern Pacific Ocean where it ranges from the Gulf of California and Magdalena Bay (Mexico) to northwest Peru, including various eastern Pacific island groups such as the Galápagos. It remains fully active at temperatures down to 17 °C (63 °F), but becomes inactive when it drops to 14 °C (57 °F). It reaches a diameter of about 30 cm (1 ft).
