Blennies: Blennioidei

Physical characteristics: Miracle triplefins are a little more than an inch (3 centimeters) long. They are light red with lighter spots. These fish have long spines in the first dorsal fin. The second dorsal is divided so that it looks like two fins, thus the name "triplefin."

Geographic range: Miracle triplefins live in the western part of the Pacific Ocean near Australia.

Habitat: Miracle triplefins live on coral reefs.

Diet: Scientists know little about the diet of miracle triplefins. The tooth structure suggests these fish eat small, bottom-dwelling invertebrates.
