Cirripedia nauplius larvae

Cirripedia nauplius

Distribution in scandinavian waters

Maximum length: 0,9 mm. Compare with the size of a hair.
Appearance: Cirripedia nauplius larvae swim with the help of three pairs of extremities. The foremost two pairs develope first into antennae. The third pair became components of the upper jaw (mandibles). In the middle of the frontal area of the carapace the nauplius eye is situated. Cirripedia nauplius larvae are usually quite distinct with their triangular shape, long frontal-lateral horns and usually an outgrowth that projects backwards. Compare with other crustaceans nauplius larvae.
Depth: From sea-level to unknown depth.
Environment: Pelagic.
Misc: These larvae are common during the summer and autumn. They catch and eat small organisms in the water so they grow and slough their shell six times before transforming into cypris larvae. Many larvae are eaten by other creatures that eat suspended particles.
Classification: Cirripedia nauplius larvae are crustaceans under the arthropod group.
