Is Acanthaster planci a near-optimal predator?
Ecological Modelling, 1989Abstract A two-dimensional model of the population dynamics of the crown of thorns starfish ( Acanthaster planci ) and its coral prey is constructed and analysed. The notion of a suboptimal-superoptimal continuum for the starfish predator is introduced. It is suggested that A. planci is a near-optimal predator on this continuum, and that population

Identification of 23-demethylacanthasterol in an asteroid, Acanthaster planci and its synthesis
Steroids, 198023-Demethylacanthasterol was identified in an asteroid, Acanthaster planci, by GC-MS analysis and direct comparison with the synthetic sample prepared from 23-demethylgorgosterol. The sterol composition of A. planci is also described.

Crown-of-Thorns Starfish (COTS) and Long-Spined Sea Urchin populations are significant indicators of coral health. COTS, which feed on coral polyps, are maintained at a population of less than 15 per hectare to avoid rapid and extensive destruction of ...

Triggering of the Stomach Eversion Reflex of Acanthaster planci by Coral Extracts
Nature, 1970RECENT observations of Acanthaster planci populations in Micronesia suggest that the animal may eat certain corals in preference to others. The starfish feeds by everting its stomach and applying it to the coral surface. Neither the stimuli evoking stomach eversion nor the mechanism by which the stomach is applied to the coral surface has been ...

Introduction: Immunomodulator are chemical compounds that can improve the body’s defense mechanisms both specific and non-specific, and non-specific induction of both cellular and humoral defense mechanisms.

De novo assembly of the transcriptome of Acanthaster planci testes
Molecular Ecology Resources, 2014AbstractA key strategy to reduce coral loss is the development of effective control method for the corallivorous crown‐of‐thorns sea star (Acanthaster planci), an omnipresent scourge and threat to the biodiversity of reefs in the Indo‐Pacific region. Limited genetic resources are available for this highly fecund species.

Response of Acanthaster planci (L.) to partial stimuli
Journal of Experimental Marine Biology and Ecology, 1976Abstract Acanthaster planci (L.) were presented with fractions of coral extract on plaster tablets. Fractions were tested in sequence in two groups of starfish, each fraction being presented daily for between 5 and 12 days. Changes in the response of the starfish were noted.
