In tropical coral reefs, crown-of-thorns specimens reach mean locomotion rates of 35 cm/min, which explains how outbreaks can damage large reef areas in relatively short periods. These are clearly sibling species and it is suggested that A. planci, the specialized coral-feeding species arose from A. brevispinus, the less specialized soft-bottom inhabitant.. In northern hemisphere coral reefs however, crown-of-thorns populations reproduce in April and May, and were also observed spawning in the Gulf of Thailand in September. Home Natural World Nine legged Starfish .  The rationale for this approach was that small changes in the survival of larvae and developmental stages would result in very large changes in the adult population. Observe, photograph and release these beautiful creatures back to nature. . Best Saltwater Spinning Reels for Under $100. Blisters on the dorsal integument broke through the skin surface and resulted in large, open sores that exposed the internal organs.

The starfish were observed to spawn (photograph) from December to January (early to mid-summer) in this region with most observations being in January. Field trials of the robot have begun in Moreton Bay in Brisbane to refine its navigation system, according to Queensland University of Technology researcher Matthew Dunbabin. This was followed by a phase of rapid growth which led to sexual maturity at the end of the second year. A. brevispinus lives on soft substrates, perhaps buried in the substrate at times like other soft substrate-inhabiting starfish, at moderate depths where presumably the surface is regular and there is little wave action. Later, Carl Linnaeus described it as Asterias planci based on an illustration by Plancus and Gualtieri (1743), when he introduced his system of binomial nomenclature.

In coral reefs in the Philippines, female specimens were found with a gonadosomatic index (ratio of gonad mass to body mass) as high as 22%, which underlines the high fecundity of this starfish. Giant Tiger Prawn (Penaeus monodon) – 10 Legs 9 – Giant Tiger Prawn (Penaeus monodon) – 10 Legs. This seems to imply that there is apparently a dense population outbreak when there has already been a more diffuse population outbreak that has been dense enough to comprehensively prey on large areas of hard coral.
