Some species of other reef inhabitants prey on this species of sea star. Various pufferfishes, Charonia species (triton shells), harlequin shrimp, and even some sea anemones have been observed to eat whole or parts of the sea stars. [3] The Blue Linckia is also prone to parasitization by a species of the parasitic gastropod Thyca crystallina.
Many of the species in this order have characteristic repeatedly branched arms (a shape known as "basket stars", which includes most Gorgonocephalidae and two species in the family Euryalidae), while the other species have very long and curling arms, and go rather by the name of "snake stars" (mostly abyssal species).
Leonardo da Vinci drew O. umbellatum and included the plant in one of his depictions of Leda and the Swan (1508–1515), in which the flowers are held in Leda's left hand. [41] [42] In folklore, the biblical star of Bethlehem is said to have fallen to the earth and shattered into pieces which became the ubiquitous white flowers. [24]
Healthy adults typically produce ample GLA from dietary linoleic acid, but borage seed oil is often marketed as a GLA supplement, under the names "starflower oil" or "borage oil". The leaves contain small amounts (2–10 ppm in the dried herb) of the liver-toxic pyrrolizidine alkaloids (PA) intermedine , lycopsamine , amabiline , and supinine ...
Protoreaster nodosus, commonly known as the horned sea star or chocolate chip sea star, [1] is a species of sea star found in the warm, shallow waters of the Indo-Pacific region. They are sometimes seen in the marine aquarium trade or dried and sold as curios.
The nine-armed sea star is a scavenger and a predator and examination of the stomach contents show that the diet consists primarily of molluscs, small crustaceans and polychaete worms. Many of the food items were swallowed whole and had been ingested by the starfish everting its stomach and engulfing its prey. [ 4 ]
In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and ...
