Reef Fish
Pinnate Batfish
Platax pinnatus · Bony fish — family Ephippidae (batfishes and spadefishes)
The pinnate batfish spends its celebrity early. Juveniles are jet black rimmed in vivid orange, ribbon-thin and taller than long, undulating through the shadows of ledges and silty margins in what is widely interpreted as mimicry of a toxic flatworm; they rank among the most photographed fish in the muck world. Adults trade the costume for silver — a tall, composed schooling batfish of lagoon edges and drop-offs, curious enough to escort divers along a wall. The two stages differ so completely that early naturalists could have described them as separate fish. Finding a juvenile is guide work: they hold tight to dark cover in shallow, protected water and seldom stay long at one site. Bring patience, favor ambient light, and keep the animal between you and its bolt-hole, never cut off from it.

深入了解
栖息地: Juveniles hug dark cover in sheltered, often silty shallows — ledges, mangrove edges, wreck shadows; adults school along lagoon and outer-reef drop-offs.
分布范围: Western Pacific from the Ryukyu Islands through the Philippines and Indonesia to northern Australia and Melanesia.
习性: Juveniles undulate ribbon-like through shadows in apparent flatworm mimicry; adults are calm, tall-bodied schoolers that sometimes escort divers along a wall for minutes.
食性: Algae, small invertebrates, and jellies; adults graze as well as pick.
体型: 通常约 0.3 m; 记录深度可达 0.45 m (total length; juveniles are taller than long, adults disc-shaped).
与它相处时的行为守则
Shoot juveniles with patience and minimal light — the orange rim overexposes easily — and let the fish keep its shadowed cover rather than herding it into the open.
保育
Not a major fishery species; juveniles are collected for aquaria despite poor survival, and mangrove loss removes nursery habitat.
