Habitat and appearance
This slender, short-snouted pipefish occurs in pockets of coral rubble on pale sand, often near sea fans. FishBase reports depths of 1–21 m and several different color phases. Color differences have contributed to historical uncertainty over how many species should be recognized.
Male brooding
Males carry the eggs in a brood pouch underneath the tail. This makes male parental care a central part of reproduction. Older names in regional records may include Micrognathus ensenadae as well as Halicampus crinitus, so comparing those records requires checking the taxonomic treatment.
