The phyllosoma is the larval stage
Larva
A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle...

Spiny lobster
Spiny lobsters, also known as langouste or rock lobsters, are a family of about 45 species of achelate crustaceans, in the Decapoda Reptantia...

Slipper lobster
Slipper lobsters are a family of decapod crustaceans found in all warm oceans and seas. Despite their name, they are not true lobsters, but are more closely related to spiny lobsters and furry lobsters. Slipper lobsters are instantly recognisable by their enlarged antennae, which project forward...

The Achelata is an infra-order of the reptant Decapoda. It contains the spiny lobsters , the slipper lobsters and the furry lobsters...

The phyllosoma larva of spiny lobsters has a long plankton
Plankton
Plankton are any drifting organisms that inhabit the pelagic zone of oceans, seas, or bodies of fresh water. That is, plankton are defined by their ecological niche rather than phylogenetic or taxonomic classification...

Benthos
Benthos is the community of organisms which live on, in, or near the seabed, also known as the benthic zone. This community lives in or near marine sedimentary environments, from tidal pools along the foreshore, out to the continental shelf, and then down to the abyssal depths.Many organisms...

is well described, studies on the planktonic phyllosoma phase have been comparatively neglected given its long duration, which has made it difficult to rear them in the laboratory. Despite the relatively large size of these larvae and their immediate recognition in plankton sorting, important identification problems due to the lack of detailed and specific morphological descriptions have precluded specific determination in many plankton samples. Recent efforts to identify phyllosoma larvae using molecular techniques have provided further insight into the ecology and distribution.
