Abstract(s)
Present thesis pretends to describe the horizontal and vertical distribution patterns of
decapod crustacean larvae in the Portuguese upwelling ecosystem. The studied taxa were
retained close to their parental populations; so, species from the inner shelf had their larvae
concentrated close to the shore, species from the shelf had their larvae over the shelf, and
the slope species had their larvae along the shelf break. The ontogenetic vertical
distribution was also analysed, and the average depth of distribution of the larval stages
varied through the larval development. The majority of the studied species had their early
zoeal stages more close to the surface and the last zoeal stages in a more deep position.
The morphological larval descriptions from laboratory cultured material of the three
selected larval forms of decapod larvae are presented: the larval development of two
closely related species of Lysmata, L. galapagensis e L. moorei (caridean shrimps), the
complete larval developments of Clibanarius aequabilis and C. erythropus (hermit crabs),
and the complete larval development of the crab Ilia nucleus.
