Family Syngnathidae

Pipefishes & Seahorses

Syngnathids have bony plates that form an articulated armor to protect the body from injury.  Pipefishes are basically straight-bodies seahorses.  They have tiny mouths that pluck or inhale small invertebrates from the substrate or water column.  After eggs are fertilized the female transfers them to a brood pouch on the male's belly until they hatch.  Seahorses are rarely found in Hawaii, from protected bays to the open ocean..
