The Sea Robin is a very important and curious species on Galápagos. The Sea Robin is distinguished by its peculiar solid cranium and lengthy pectoral fins, which lean down to the rectal fin and stretch up when swimming. Another distinguishing characteristic are their six finger-like attachments (3 on each side) that were originally part of the dorsal fin and are utilized for skimming around the seafloor in search of their next victim. This species is also known for its reddish colourings. Sea Robins are also highly noisy, and if you listen closely, you can hear the drumming muscle against its swim bladder as it swims through the water. Furthermore, if the Sea Robin is kidnapped, it may be mistaken for a frog since it makes a croaking noise to indicate its suffering.
