When sexually mature, L. laevigata release eggs and sperms into the water column, where fertilization takes place (Yamaguchi 1977). The Blue Sea Star is found in the Indo-Pacific region growing up to 40cm in length. Also known as the Blue Linckia. They are known to be creatures with remarkable regenerative abilities, and capable of defensive autotomy against predators. On a patch reef surrounded by sand, the movements of L. laevigata conformed to Underwood's random walkmodel in most respects except that animals navigated unidirectional paths across the reef. (A, C) Indo-Malay Ar chipelago with sample sites (for abbreviations see Table 1) as well as oceanographic pat- Linckia is a genus of sea stars found mainly in the Indo-Pacific region. The latter becomes blue to blend completely with Linckia laevigata (it can also be beige, red, yellow...). It consists of an upper epidermis layer, a middle thick, mutable, connective tissue dermis (or the catch tissue) and a coelomic epithelium (Ruppert, Fox & Barnes 2004). The genus is named after the German naturalist Johann Heinrich Linck (1674–1734).. Systematics. Linckia is a genus of sea stars found mainly in the Indo-Pacific region. As in all other known starfish, the eyes of L. laevigata are situated at the very tip of each arm and in moving animals the tip bends 80°–120° upwards which … The genus is named after the German naturalist Johann Heinrich Linck (1674–1734).. Systematics. Linckia laevigata (sometimes called the "blue Linckia" or blue star) is a species of sea star in the shallow waters of tropical Indo-Pacific.. Linckia laevigata (A, B) and Thyca crystallina (C, D). Contents. They reproduce asexually. The blue starfish Linckia laevigata is widely distributed on Indo-Pacific coral reefs and hosts the parasitic snail Thyca crystallina. Linckia laevigata, Linckia browni, Linckia crassae, Linckia hondurae Linckia miliaris, Linckia rosenbergi, Linckia suturalis, Linckia typus Asterias laevigata Ophidiaster clathratus, Ophidiaster crassa, Ophidiaster laevigatus, Ophidiaster miliaris, Ophidiaster propinquus. At the edge of the reef, animals either turned back onto the reef or moved away across the sand, and this behaviour was studied in translocation experiments. They reproduce asexually.
Description and characteristics; See also; References; External links; Description and characteristics. The body wall of Linckia laevigata is approximately 3-4mm thick (Motokawa & Wainwright 1991). The shrimp finds its food near the starfish's mouth, while the starfish takes advantage of this care and cleaning that it could not do alone. In other words, they have separate male and female individuals (Yamaguchi 1977). Males were observed to spawn before females in the lab and both sperms and eggs are milky white in color in this species (Laxton 1974). This behavior results in a beneficial effect as the animal will be prevented from feeding on a previously grazed area (Thompson & Thompson 1982). (Kochzius, et al., 2009; Magsino, et al., 2000; Yamaguchi, 1977)Biogeographic Regions; oriental; australian; indian ocean; pacific ocean; Habitat. Origin. Linckia laevigata inhabits the tropical waters of the Indian and Pacific Oceans, from the western Indian Ocean to southeastern Polynesia. As in all other known starfish, the eyes of L. laevigata are situated at the very tip of each arm and in moving animals the tip bends 80°–120° upwards which raise the eyes from the substrate (figure 1a,b). Linckia laevigata - Blauer Seestern Vorkommen: Japan, Indopazifik PH: 8.1 - 8.5 KH: 7-14 Endgröße: bis zu 20 cm Aquariumgröße: ab 400 l Temperatur: 24-26 °C Locomotion. Common name Blue sea star Blue linckia. Geographic Range. autotomy) (Ruppert, Fox & Barnes 2004). According to the results of a previous study on the movements of L. laevigata, this sea star species tends to move unidirectionally (Thompson & Thompson 1982). Linckia laevigata is gonochoristic. Like all invertebrates, the Linckia …
They are known to be creatures with remarkable regenerative abilities, and capable of defensive autotomy against predators. Reproduction Linckia laevigata is able to reproduce both asexually and sexually.. Asexual reproduction Species of the genus Linckia is known to be capable of casting off part of their body when under threat/stress (i.e.
