The Crown-of-Thorns Starfish (Acanthaster Planci) is a species of echinoderm that appears in both Endless Ocean and Endless Ocean: Blue World.

In-Game Description

Endless Ocean

"These blue-gray echinoderms have compact bodies with multiple arms that are covered in thick orange spines. the spines contain a potent poison that has been responsible for human fatalities. This creature can be seen year-round in Comb Reef."

Endless Ocean: Blue World

"Its countless arms and body are covered in thick orange spines. The spines contain a toxin that can be poisonous to humans. It is very painful and can cause nausea, swelling, and infection, so it must be approached with caution. It feeds on coral, which turns white and dies when eaten. Conch shellfish are unaffected by the poison and often eat these starfish."


In the first game, a large cluster of them can be found atop Comb Reef in the southeastern quadrant of coordinate square C-4, atop a large growth of green plate corals. they blend in quite well, so look carefully.

In the second game, they can be found in Zahhab Region around E-1, D-3 and E-3, often atop the Stone Castle. Once again, they are very tricky to locate.


They are just stuck on a rock.


This can only be found during the day with Hayako Sakurai.
