- Remarks: Calloplesiops altivelis is fairly common on protected coral reefs in the Maldives. However, it is rarely seen by divers because of its secretive habits. When threatened it may present its tail to the intruder displaying the prominent posterior eyespot. This is thought by some to be mimicry of the Spotted moray eel.
