Through Coral
The species in this genus are a contributor to coral reef degradation because they prey on a large amount of live coral at high density.
Species
These species are listed in the World Register of Marine Species:
Some sources add Acanthaster ellisi, (Gray, 1840) but it is now considered as a subspecies of A. planci in the eastern Pacific.
Recent molecular work has suggested that Acanthaster planci is a species complex of up to 4 different species that have yet to be separately described (Vogler et al., 2008).
Haszprunar, Vogler & Wörheide (2017) suggest to split "A. planci" in :
- Acanthaster planci (Linnaeus, 1758) -- Northern Indian Ocean, always purple-blue and red
- Acanthaster mauritiensis de Loriol, 1885 -- Souther Indian Ocean
- Acanthaster solaris (Schreber, 1795) -- Pacific Ocean (max. 23 arms)
- Acanthaster benziei Wörheide, Kaltenbacher, Cowan & Haszprunar, 2022—Red Sea (max. 14 arms).
