There are many kinds of Triggerfish. This is a Clown Triggerfish. They are very feisty and will bite your hand when trying to feed them. If you keep them in an aquarium they will bite tubes and stuff and cause real havoc! They have personality.
Featherstar on gorgonian coral. The featherstar is a marine invertebrate. It is an ancient and primitive echinoderm, a member of the group of invertebrates that includes the starfish. It uses its feathery and fragile arms to catch and convey microscopic plankton and detritus to its mouth at the base of its arms. Unlike the closely-related sea lily, a featherstar is a free-swimming animal. Photographed at Misool, Raja Ampat, West Papua, Indonesia.
