Big Fish
Giant Grouper
Epinephelus lanceolatus · Bony fish, family Epinephelidae
The giant grouper is the Indo-Pacific's resident submarine: a fish the size of a chest freezer, drab olive-gray with a vast frog mouth, hanging in the shade of a wreck companionway with tiny eyes tracking everything. Australia's Yongala wreck made the species famous among divers: its resident giants loom out of the gloom beside bull rays and sea snakes, treating the hull as a fiefdom. Encounters elsewhere are scattered and memorable for their rarity; wild adults have been fished out of most of Asia, and a giant meeting you at depth with calm, proprietary curiosity is a privilege fewer reefs can offer each decade. Aquaculture now supplies the food trade the wild fish once fed.

最佳月份一览
深入了解
栖息地: Wrecks, caves, and lagoon pinnacles; solitary adults hold large territories around favored structure
分布范围: Tropical Indo-Pacific from the Red Sea and East Africa to Australia, Japan, and the central Pacific, nowhere common
习性: A cave-dwelling colossus that spends daylight suspended in shade, drifting out to inspect visitors with ponderous confidence. Individual fish occupy the same wreck or bommie for many years and become local celebrities. Like its Atlantic counterpart it can produce a booming territorial drum.
食性: Spiny lobsters, crabs, fish including small sharks and rays, and juvenile turtles, engulfed whole
体型: 通常约 1.8 m; 记录深度可达 2.7 m (total length; the largest bony fish resident on coral reefs, reportedly to 400 kg).
与它相处时的行为守则
No feeding (it rewired the behavior of famous individuals in the past), no touching, and give the fish the right of way in wreck corridors and caves.
保育
Currently assessed Data Deficient: wild populations are sparse and hard to census after decades of the live reef-food-fish trade; several range states protect it outright.
