安达曼海珊瑚礁上方的红牙鲹鱼群

l of redtoothed triggerfish (Odonus niger) forages for zooplankton above a Porites coral reef in the Andaman Sea, showing reef fish schooling behaviour across Indo-Pacific reef ecosystems. Unlike most triggerfish, which hunt invertebrates along the seabed, Red-toothed Triggerfish feed almost entirely in the water column, rising and falling with the current. Their deep blue bodies catch violet light against open water above the coral. 4K, wide angle, vertical handheld medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
