Luzon Island, Philippines
This small triplefin is resting on some coral polyps. Shown in the retracted position with the tentacles hidden, the coral polyps are only about 3/8 inch across. The positioning of its eyes allow it to see all around, helping it avoid predators. The transparency of its body helps it blend against the reef-- its fins and much of its body are barely visible.
