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.

Il mese migliore, a colpo d'occhio
Capirle
Habitat: Coastal waters, lagoons, mangrove channels, and reef overhangs; gulps surface air with a modified swim bladder, which lets it thrive in stagnant backwaters
Distribuzione: Western Atlantic from Virginia to Brazil including the entire Caribbean and Gulf of Mexico, plus tropical West Africa
Comportamento: 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.
Dieta: Schooling fish and crustaceans, taken in explosive inhaling strikes, mostly at night
Dimensioni: tipicamente intorno a 1.5 m; documentato fino a 2.5 m (total length; large females exceed 100 kg).
Come comportarsi in sua presenza
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.
Conservazione
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.
