Crab Larvae


Megalopa Crab are the final stage larvae of Crabs. During the larvae stages of their life cycle, this Crustaceans are found in the water column and usually active at night when they feeds, among tiny planktons. This particular Crab is less than 1 cm in size and I was surprised to noticed something on top of its shell, which turned out to be a Barnacle. The Barnacle was extending its feather-like feeding appendages, called cirri brushing through the water collecting planktons. Had to take many shots to capture the sequence when the cirri were fully extended as shown in both pics.


Picture was taken during Black Water dive at night, meaning in water column over areas with depths of 100 meters or deeper.
