Cephalopods
Broadclub Cuttlefish
Sepia latimanus · Cephalopod mollusk, family Sepiidae; the largest cuttlefish on tropical Indo-Pacific reefs
The broadclub cuttlefish is the big, watchable cuttlefish of tropical reefs, second in size only to Australia's giant, and the one most likely to meet a diver's gaze with its strange W-shaped pupil and simply hold position, hovering on the ripple of its fin skirt. Its party piece is the passing cloud: bands of dark color strobing forward across face and arms while it stalks a crab, apparently dazzling the prey into stillness before the twin feeding tentacles fire. Individuals often tolerate long, close observation, cycling camouflage and curiosity in equal measure. In breeding aggregations males guard females and flash zebra patterns at rivals, sometimes courting on one body half while warning on the other. Eggs go deep into branching coral like clusters of white grapes. Approach slowly; ink means the show is over.

最佳月份一览
深入了解
栖息地: Coral reefs and adjacent seagrass and rubble, hovering near branching coral where it hunts and breeds.
分布范围: Indo-Pacific from the Andaman Sea through the Coral Triangle to northern Australia, Micronesia, and southern Japan.
习性: Famous for the passing-cloud display: bands of dark color strobing forward over the face and arms to mesmerize prey; breeding males guard females and flash zebra patterns at rivals, sometimes displaying differently on each body half.
食性: Crabs, shrimp, and fishes struck with twin feeding tentacles after a slow stalk.
体型: 通常约 0.3 m; 记录深度可达 0.5 m (mantle length; heavyweights reach roughly 10 kg).
与它相处时的行为守则
Move gently and stay to one side; a relaxed animal will hold position and cycle displays for minutes, while a startled one inks and the audience is over. Leave egg clusters in branching coral untouched.
保育
Formally Data Deficient; taken in reef fisheries across parts of the range, and breeding-season animals are conspicuously easy targets.
