@theplanktonproject: Two barnacle (Cirripedia) larval stages together - the ones with the horns, moving erratically, are the nauplii. The little seed-looking guy is the following larval stage, the cyprid. It is the non-feeding cyprid that will find a permanent home on the substrate and transform in the barnacles we know and love. #marinebiology #marinebiologyuk #sea #ocean #biology #plankton #marinetaxonomy #wildlife #nature #microscopy #microorganism #zooplankton #Science #norfolkwildlife #microscope #barnacle #barnacles #crustacean #crustaceans #cyprid #nauplius #nauplii
