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.

Congratulations Albert, that great catch and somehow alien-like encounter earned you a Spotting of the Week! Also, many of us had never seen a crab larva ;-)

"Spotting of the Week! How do crustaceans such as crabs begin their life? Between hatching from their eggs and reaching adult form they go through a number of larval and immature stages. For decapods such as crabs the last developmental or post-larval stage is known as 'megalopa'. As seen here, that stage is quite similar to the adult form. What about that 'appendage' on top of our mini-crab? It turns out to be a barnacle! Check out the spotting for more information".

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!
