礁石甲壳类行为：安达曼海泰国裂缝中的纹画刺虾

ed spiny lobster (Panulirus versicolor) extends its banded blue and white antennae from a reef crevice in characteristic foraging posture, its colouration among the most distinctive of Indo-Pacific reef crustaceans. Nocturnally active, this species shelters in reef crevices through daylight, emerging after dark to scavenge organic matter across the substrate. Its long antennae extend beyond the den, detecting movement and chemical cues nearby. 4K, wide angle, vertical, close up, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
