Crown-of-thorns starfish
Figure 1. Crown-of-thorns starfish and their legacy. (A) A group of crown-of-thorns starfish converge on the remaining small piece of living coral tissue (lc) on the surface of a tabular coral (Acropora sp.) The other coral tissue has just been consumed by the starfish so that only the white skeleton remains (cs). (B) After crown-of-thorns starfish have removed the living coral tissue, the expo...
متن کاملModel to manage and reduce crown-of-thorns starfish outbreaks
The crown-of-thorns starfish (COTS) Acanthaster planci is one of the largest causes of coral cover loss on Australia’s Great Barrier Reef. Numerous trophic-mediated and anthropogenic-related hypotheses, singly or in combination, have been proposed to explain COTS outbreaks, but the evidence remains inconclusive. There is, however, an urgent need for effective control and mitigation strategies. ...
متن کاملPhylogeography of the Crown-of-Thorns Starfish in the Indian Ocean
BACKGROUND Understanding the limits and population dynamics of closely related sibling species in the marine realm is particularly relevant in organisms that require management. The crown-of-thorns starfish Acanthaster planci, recently shown to be a species complex of at least four closely related species, is a coral predator infamous for its outbreaks that have devastated reefs throughout much...
متن کاملBody size and substrate type modulate movement by the western Pacific crown-of-thorns starfish, Acanthaster solaris
The movement capacity of the crown-of-thorns starfishes (Acanthaster spp.) is a primary determinant of both their distribution and impact on coral assemblages. We quantified individual movement rates for the Pacific crown-of-thorns starfish (Acanthaster solaris) ranging in size from 75-480 mm total diameter, across three different substrates (sand, flat consolidated pavement, and coral rubble) ...
متن کاملSmooth muscle contractile action of the venom from the crown-of-thorns starfish, Acanthaster planci.
The fraction (venom B) of spine venom from the crown-of-thorns starfish (Acanthaster planci) caused contractions of the uterus of rats and enhanced vascular permeability in rabbits. The venom B-induced contraction of the smooth muscle was depressed by inhibitors of prostaglandin synthesis such as indomethacin or aspirin, but not by the anticholinergic agent, atropine. The fraction with the uter...
