Genus
Common name: Crown-of-Thorns Starfish
Scientific name: Tamaria
Tamaria is a genus of starfish in the family Acanthasteridae, commonly known as the Crown-of-Thorns Starfish. These starfish are notorious for their impact on coral reefs as they feed on coral polyps. They are characterized by their multiple arms covered with venomous spines. While they play a natural role in controlling coral growth, outbreaks can lead to significant coral decline. In the aquarium trade, they are generally not recommended due to their destructive feeding habits and potential to harm other tank inhabitants.
