Pygmy Seahorse
Hippocampus bargibanti · Bony fish — family Syngnathidae; Bargibant's pygmy seahorse, the classic gorgonian-dwelling pygmy
Nobody found a Bargibant's pygmy seahorse in the wild first. The species turned up in 1969 on a gorgonian already sitting in a New Caledonia aquarium, because a two-centimeter seahorse studded with polyp-matched tubercles is effectively part of its host. Each pair or small group spends adult life on a single Muricella sea fan, pink-on-pink or yellow-on-yellow, tails wrapped around the branches. Guides locate them by knowing individual fans, then point a stick at what looks like nothing until your eyes adjust and the fan grows a face. The photography ethics are blunt: the fans live on current-swept walls where a misplaced fin does decades of damage, and repeated strobe barrages visibly stress the animals, so many operations cap flash frames per group. Skip the shot unless your buoyancy has earned it.

理解を深める
ハビタット: Lives exclusively on Muricella gorgonian sea fans on current-swept slopes and walls, matching the host's polyp color and texture.
分布域: Coral Triangle heartland — Indonesia, Philippines, Malaysia, Papua New Guinea — extending to northern Australia, Micronesia, and southern Japan.
生態・行動: Pairs and small groups spend adult life on a single fan, tails wrapped around branches; movement is measured in centimeters per day.
食性: Minute crustaceans picked from the water and the fan surface.
サイズ: 目安は 0.02 m; 確認済みの最大記録 0.025 m (height; among the smallest seahorses known).
出会ったときの正しいふるまい方
Let the guide point, keep buoyancy faultless off the wall, never touch the fan, and accept a capped number of flash frames; many operators limit or ban strobes on pygmies.
保全
Formally Data Deficient; practical risks are damage to host gorgonians and cumulative harassment at heavily dived fans.
