Smooth 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 کاملExtraction and characterization of pepsin-solubilized collagen from the body wall of crown-of-thorns Starfish (Acanthaster planci)
Pepsin-solubilized collagen (PSC) was extracted from the body wall of crown-of-thorns starfish (COTS) (Acanthaster planci) using pepsin digestion in 0.5 M acetic acid. The electrophoretic pattern of PSC showed that it consisted of two α chains (α1 and α2 chains). In addition, the peptide mapping showed that there were some differences in peptide patterns among PSC, calf skin collagen and salmon...
متن کاملPopulation Study Survey of Acanthaster planci, the Crown-of-Thorns starfish on the North-West Coast Moorea, French Polynesia
Outbreaks of Acanthaster planci, the Crown-of-Thorns starfish, have been known to cause considerable amounts of damage to coral reef systems. Surveys of A. planci populations in Moorea, French Polynesia in 2004 indicated the island was experiencing the beginning stages of an outbreak. The goal of the present study was to survey the population densities of these sea stars at 3 sites on the north...
