Open encyclopedia reference
The false-eye seahorse, or flatface seahorse (Hippocampus planifrons) is a species of marine fish of the family Syngnathidae. It is endemic to Australia, from Shark Bay to Broome, where it is found in intertidal rockpools, shallow algae and weedy or rubble reef habitats. It is expected to feed on harpacticoid, calanoid, and cyclopoid copepods, caridean and gammaridean shrimps, and mysids, similar to other seahorses. This species is ovoviviparous, with males brooding eggs in a brood pouch before giving birth to live young.
