In total, 61 holoplankton
taxa belonging to 7 categories: Protozoa, Cnidaria, Rotifera, Crustacea (Copepoda, Cladocera, Ostracoda, Amphipoda and Mysidacea), Chaetognatha, Mollusca, Larvacea, and 8 different types of meroplankton were also recorded (Table IV).
They may be either whole life cycle in the water column (holoplankton
) or be temporarily in this site (meroplankton), when the larvae is planktonic but the adult individual is nektonic or benthic [2, 3].
of the Santa Catarina coast, southern Brazil.
This led to a large difference between holoplankton
and meroplankton abundance (Fig.
Meroplanktonic calcified organisms such as juvenile gastropods and foraminifera are adversely affected as C[O.sub.2] levels increase (Cigliano et al., 2010), but carbon dioxide seeps have not so far been used for the study of ocean acidification on holoplankton
. Here, we analyzed phytoplankton along a natural pH gradient near underwater C[O.sub.2] seeps.
 reported over 50 zooplankton taxa with holoplankton
comprising >80% of the taxa sampled and Rotifera (22 species) dominating.

Ship ballast water is a major source of introductions of coastal marine species, particularly of holoplankton
and meroplankton with relatively long-lived planktonic larvae.
Seasonal composition and food web relationships of marine organisms in the nearshore zone--including components of the ichthyoplankton, meroplankton, and holoplankton

Leaving to one side formal classifications based on size and zoological groupings, it is important to distinguish between two different types of zooplankton organisms: those that pass all their life in the plankton (holoplankton
) and those that only colonize the pelagic environment at some stage in their life cycle (meroplankton).
The entire contents of each sample were analyzed, except in cases where larvae and holoplankton
were extremely numerous.
Such animals are termed holoplankton
, while the temporary residents of the plankton (such as the larval forms) are called meroplankton.
