Sharks
Galápagos Shark
Carcharhinus galapagensis · Cartilaginous fish, family Carcharhinidae
The Galápagos shark is what most people picture when they hear the word shark: three meters of gunmetal muscle, tall dorsal, blunt round snout, cruising a boulder slope in gin-clear island water. It belongs to the remote places: the same species patrols Wolf and Darwin, Bermuda's outer banks, and the Revillagigedo seamounts, one of the odd distributions in the shark world, stitched between far-flung islands with deep ocean in between. Encounters are steady rather than dramatic; the shark holds its line, takes your measure on a slow pass, and resumes its rounds as though you were furniture.

理解を深める
ハビタット: Clear water around remote oceanic islands and seamounts: rocky drop-offs, boulder slopes, and adjacent blue water
分布域: Scattered across the world's oceanic islands: the Galápagos and Revillagigedos, Hawaii, Bermuda, Lord Howe and the Kermadecs, Ascension, and similar isolated outposts
生態・行動: A big, classically shark-shaped carcharhinid that patrols island walls in twos and threes, often shadowing divers with steady, wide circuits. Around bait or in packs it grows bold and pushy; on an ordinary wall dive it reads as confident but unhurried company.
食性: Bottom fish, octopus, and squid, with larger animals taking rays and small sharks
サイズ: 目安は 2.5 m; 確認済みの最大記録 3.7 m (total length).
出会ったときの正しいふるまい方
Stay off bait lines, keep the group together on blue-water exposures, and meet close passes with steady eye contact rather than retreat.
保全
Assessed Least Concern in aggregate, but individual island populations are small, isolated, and quick to deplete. Several of its strongholds are large marine reserves for good reason.
