چکیده
Abstract The short spined crown-of-thorns starfish Acanthaster brevispinus inhabits deeper water soft bottom habitats, in contrast to the more infamous Indo-Pacific species complex of which population outbreaks have been responsible for widespread coral mortality throughout Indo-West Pacific region. has not previously regarded as a threat corals or reefs. Here, we report A. occurring on mesophotic off-reef inter-reef habitats 20–70-m depths dominated by solitary off both western and eastern coasts Australia. On Ningaloo Reef, were found mushroom ( Cycloseris distorta ) beds using an underwater towed camera further exploration remotely operated vehicle (ROV) confirmed predation C. . southern Great Barrier large numbers habitat dendrophylliid Heteropsammia cf. cochlea. Predation H. cochlea was also directly observed. This is first hard brevispinus, while there are yet be any records this species, such could significant effect assemblages.

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 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...
متن کاملPhylogeography and evolution of the crown-of-thorns starfish Acanthaster planci
In the face of ever-increasing threats to coral reef ecosystems, it is essential to understand the impact of natural predators in order to devise appropriate management strategies. Destructive population explosions of the crown-of-thorns starfish (COTS) Acanthaster planci have devastated coral reefs throughout the Indo-Pacific for decades. But despite extensive research, the causes of outbreaks...
متن کاملIn situ culturing of larvae of the crown-of-thorns starfish Acanthaster planci
Larvae of the crown-of-thorns starfish Acanthaster planci were reared in situ at 5 and 15 m depths using submersible culture chambers. Larvae developed normally and most were at the mid brach~olaria stage after 12 d. All larvae showed signs of feeding as evidenced by yellow and green coloration in their digestive tracts. In sltu culturing of A. planci larvae is a feasible means of investigating...
متن کاملBenthic Predators Influence Microhabitat Preferences and Settlement Success of Crown-of-Thorns Starfish (Acanthaster cf. solaris)
Like most coral reef organisms, crown-of-thorns starfish (Acanthaster spp.) are expected to be highly vulnerable to predation as they transition from a planktonic larval phase to settling among reef habitats. Accordingly, crown-of-thorns starfish might be expected to exhibit behavioural adaptations which moderate exposure to predation at this critical stage in their life history. Using pairwise...
