Biochemical stimuli for feeding in Acanthaster planci (L.)

Journal of Experimental Marine Biology and Ecology, 1976
Abstract The typical feeding response of the Crown of Thorns Starfish Acanthaster planci (L.) can be induced by mucoproteins of molecular weight greater than 200,000 daltons found in mucus obtained from corals of the genera Acropora and Fungia .

Bias in manta tow surveys of Acanthaster planci

Coral Reefs, 1990
To investigate the biases associated with manta tow surveys of Acanthaster planci, counts obtained by manta-towed observers were compared with counts made on SCUBA swims under a limited range of conditions. Five 10 m wide strip transects on different parts of two reefs and with different densities of A. planci were surveyed.

New Steroidal Glycosides from the Starfish Acanthaster planci

Chemistry of Natural Compounds, 2016
Two new and three known polyhydroxysteroid glycosides were isolated from the MeOH extract of the starfish Acanthaster planci. The structures of the isolated compounds were elucidated using NMR and mass spectrometry. The new glycosides had the same aglycon, (24S)-24-methyl-5α-cholestane-3β,4β,6α,8,15β,16β,28-heptaol, and different carbohydrate fragments,

Haemodynamic and haematologic effects of Acanthaster planci venom in dogs

Toxicon, 1994
This study was designed to examine haemodynamic and haematologic effects of the crown-of-thorns starfish venom (Acanthaster planci venom: APV) in dogs. Severe systemic hypotension, thrombocytopenia and leukopenia were induced by APV (1.0 mg protein/kg i.v.), followed by gradual return to the baseline level within 60 min.

Is Acanthaster planci a near-optimal predator?

Ecological Modelling, 1989
Abstract 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

Acanthaster planci outbreak initiation: A starfish-coral site model

Ecological Modelling, 1990
Abstract A lumped parameter model of the dynamics of the crown of thorns starfish (predator) and hard corals (prey) based on simple recruitment, growth and feeding equations was used to simulate the conditions that would lead to a starfish outbreak.

Response of Acanthaster planci (L.) to partial stimuli

Journal of Experimental Marine Biology and Ecology, 1976
Abstract 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.
