Wax digestion in a crown-of-thorns starfish

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975
Abstract Digestive enzymes of Acanthaster ellisii are exceptionally effective in hydrolyzing a wax ester, cetyl palmitate, the major energy reserve of reef corals.

Management of crown-of-thorns starfish injury

Foot and Ankle Surgery, 2004
A 30-year-old man stepped on a crown-of-thorns starfish and sustained penetrating injuries to his foot by the spines of the starfish. Radiographs confirmed the presence of radioopaque foreign body spines in his foot. The significance of performing early surgical excision of the spines in the theatre under anaesthesia using radiographic control is ...

Crown-of-thorns starfish management conundrums

Coral Reefs, 1992
Since the early 1960s, debate over managements of the phenomenom of large populations of the coral eating crown-of-throns starfish has presented a major ecological conundrum: Is it normal, human-induced or human-increased? Whilst that is unresolved there is a second conundrum for the reef manager: Should there be systematic controls?

Simulation of coral reefs and crown‐of‐thorns starfish

Environmetrics, 1993
AbstractCoral reefs are subject to attack and predation by the starfish Acanthaster planci or crown‐of‐thorns. This paper describes a simulation model of the natural processes of a coral reef and its reaction to, and recovery from starfish attacks. The modelling of a reef section is based on a pixel representation of the area.

Predation on crown-of-thorns starfish larvae by damselfishes

Coral Reefs, 2016
Examining the functional response of predators can provide insight into the role of predation in structuring prey populations and ecological communities. This study explored feeding behaviour and functional responses of planktivorous damselfishes when offered captive reared larvae of crown-of-thorns starfish, Acanthaster sp., with the aim of ...

Is the crown-of-thorns starfish degrading the great barrier reef?

Journal of Theoretical Biology, 1992
The phenomenon of crown-of-thorns starfish outbreaks on the Great Barrier Reef (GBR) is treated on a large scale as analogous to a disease (starfish outbreaks) spreading through a community of susceptibles (individual reefs). A simple (epidemiological) model is found which well represents the extant data on starfish abundance for the central sector of ...

Crown-of-thorns starfish on the great barrier reef

Endeavour, 1982
Abstract During the 1960s and 1970s the bulk of the hard coral cover of reefs in the central region of Australia's Great Barrier Reef was killed as a result of population outbreaks of the coral-eating starfish, Acanthaster planci . Millions of starfish were involved.

Elevated predation on crown-of-thorns starfish in no-take marine reserves

Current Biology
Predator removal can destabilise and devastate ecosystems, particularly if a species released from top-down control can itself fundamentally alter the system1. On Indo-Pacific reefs, coral-eating crown-of-thorns starfish (CoTS, Acanthaster spp.) threaten ecosystem function and resilience due to their propensity to undergo destructive population ...

Taphonomy of crown-of-thorns starfish: implications for recognizing ancient population outbreaks

Coral Reefs, 1995
A field experiment was conducted to determine whether in situ mass mortality of Acanthaster planci subsequent to a simulated outbreak would leave a recognizable signature in surficial reef sediments. Constituent particle analyses comparing sediments that received starfish carcasses to those that did not revealed that, after a four year interval, the ...

Liver damage by the crown-of-thorns starfish (Acanthaster planci) lethal factor

Toxicon, 1990
Upon autopsy of mice injected with the crown-of-thorns starfish (Acanthaster planci) lethal factor, a change in color of the liver, swelling of the gall bladder and jaundice were observed. After administration of the lethal factor into mice, activities of glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), lactate ...
