Big Fish
Atlantic Tarpon
Megalops atlanticus · Bony fish, family Megalopidae
Tarpon are armored in the ocean's shiniest currency: scales like minted coins, a scoop jaw set in permanent skepticism, eyes the size of golf balls. By day they hover in silver rows inside Cayman grottos and cenote mouths, unbothered by divers a fin's length away; by night they turn into muscle and reflex, using dive lights as hunting lamps and hitting baitfish with strikes you feel as pressure. The species barely registers as food fish through much of its range (the sport is in the jump, anglers say), which leaves big, old, diver-tolerant schools decorating the Caribbean's ledges like heirlooms.

最佳月份一览
深入了解
栖息地: Coastal waters, lagoons, mangrove channels, and reef overhangs; gulps surface air with a modified swim bladder, which lets it thrive in stagnant backwaters
分布范围: Western Atlantic from Virginia to Brazil including the entire Caribbean and Gulf of Mexico, plus tropical West Africa
习性: Daytime tarpon idle in packs under ledges, in cavern mouths, and beneath docks, all mirror-chrome scales and disdain, letting divers approach within touching distance. At night they switch on: riding dive lights to ambush silversides, detonating through bait clouds in silver flashes. The rolling surface gulp of air is the species' signature.
食性: Schooling fish and crustaceans, taken in explosive inhaling strikes, mostly at night
体型: 通常约 1.5 m; 记录深度可达 2.5 m (total length; large females exceed 100 kg).
与它相处时的行为守则
On night dives, hold your beam steady and off other divers so hunting fish work the edge of it rather than the group; no feeding, and no crowding cavern schools against the rock.
保育
Vulnerable: a slow-growing, late-maturing fish pressured by harvest in parts of Latin America and West Africa and by loss of mangrove nurseries; largely catch-and-release where the sport fishery rules.
