One of the most noticeable features of the crown-of-thorns starfish is the spines, which may be up to two inches long. comm., in Birkeland and Lucus 1990). De'ath, G. and Moran, P.J. Acanthaster planci is a significant coral predator and is known as a keystone species.

The crown-of-thorns starfish Acanthaster planci is a venomous species from Taiwan whose venom provokes strong hemolytic activity. Predators, e.g.

Current Distribution: Acanthaster planci are found on Indo-Pacific coral reefs, the Red Sea and on Australia 's Great Barrier Reef. Acanthaster planci (L., 1758) ... Glynn (1974) noticed that Acanthaster distribution was discontinuous between Central America and the Gulf of California and the Revillagigedo Islands, but suggested that with more studies, this would prove incorrect. of Acanthaster planci (L.) Waters 1 J. S. LUCAS 2 Abstract A dispersed of planci on Lode stone Reef regularly June to 1973. These were similar magnitude timing to those aggregated of A . This species is particularly common on the Great Barrier Reef of Australia. planci Reef waters.

These sea stars can be from nine inches to up to three feet in diameter.

polychaete worms (Hermodice carunculata), a starfish (Acanthaster planci) and fish (Chaetodon species) feeding on Palythoa colonies, accumulate high toxin concentrations in their organs, where PTX is stored in its active form. To understand the hemolytic properties of A. planci venom, samples were collected from A. planci spines in the Penghu Islands, dialyzed with distilled water, and lyophilized into A. planci spine venom (ASV) powder. Distribution of Acanthaster planci at Lord Howe Island Solomon Islands South Pacific Ocean the southernmost Indo-Pacific reef, Coral Reefs 9 (3): 145-148. This image is a broad example of a phylogenetic tree, when traced down into more specific branches of the tree you can eventually find Acanthaster planci.The phylogenetic tree shown above displays the three major domains (bacteria, archaea, and eukaryota) which are grouped into different sections of the tree. Acanthaster planci typically attacks a coral head from the top, extruding its stomach and releasing soft tissue-digesting enzymes, leaving a distinctive scar. (Moran, 1988a; Moran, 1988b) There was a progressive increase gonad (June) (December) rapid decline to low level in January . Background.

Geographic Range. Original Distribution: Indo-Pacific, First identified in 1705 by Georg Rumphius, and given a scientific name in 1758. Crown-of-thorns starfish (Acanthaster planci) are beautiful, prickly and devastating creatures that have caused mass destruction to some of the world's most beautiful coral reefs.

It has the potential to alter coral ecosystems in significant and important ways.

POPULATIONS of the coral predator, Acanthaster planci, are changing their distribution on the Great Barrier Reef.

1998. Acanthaster planci is found throughout the Indo-Pacific region, ranging from the Indian ocean (Red Sea and East Africa) to the Pacific (from mainland Japan south to Lord Howe Island, and from the west coast of Panama to the Gulf of California). Episodic population outbreaks of the crown-of-thorns starfish, Acanthaster planci, have resulted in widespread degradation of Indo-Pacific coral reefs [].While the ultimate cause of outbreaks is still the subject of debate, most researchers agree that exploring the reproductive biology and early life history of A.planci is essential in understanding mechanisms that lead to outbreaks.
