Crown of Thorns Starfish
The Crown of Thorns Starfish (Acanthaster planci)
is found on coral reefs throughout the Indian and Pacific oceans. It feeds almos exclusively on coral, and during "population outbreaks" can result in extensive damage to a coral reef, damage that can take many years for the reef to recover from.

Purple Sunstar (Solaster endeca)
The Purple Sunstar (Solaster endeca)
is found in the Atantic Ocean from the coasts off Canada south to the Gulf of Maine, as well as off the coasts of Greenland and the British Isles. Although purple is the most common color, individual coloration ranges from dirty cream to orangish-yellow to bright pink-purple.
