Abstract
This scientific communication represents the record of Pontella marplatensis (Ramirez – 1966), in the station near Cabo Frio Island (Arraial do Cabo RJ – Brazil). This species of marine copepod ocurred in the zooplankton sample on September 15, 2010, obtained through horizontal drag with mesh net of 100 µm and 40 cm in diameter.
Highlights
Copepods are small crustaceans that are mostly included in the mesozooplankton, i.e., the size fraction between 0.2 and 20mm (SIEBURTH; LENX, 1978)
Monteiro-Ribas marplatensis, which is included in this family, was described from the Argentine Sea (Mar del Plata) by Ramirez in 1966; and has been found in Texas (Gulf of Mexico) (WAGGETT; BUSKEY, 2008)
The presence of P. marplatensis in the state of Espírito Santo, Brazil, was recorded by Rocha & Fernandes (2009). Until now, this copepod has not been recorded from Arraial do Cabo, despite several surveys made in this region between 1974 and 1975 and from 1995 until now
Summary
Copepods are small crustaceans that are mostly included in the mesozooplankton, i.e., the size fraction between 0.2 and 20mm (SIEBURTH; LENX, 1978). Marine copepods belong to five orders (DIAS; ARAUJO, 2006), including the Calanoida. This order comprises 40 families that contain mostly holoplanctonic species (VEGA-PÉREZ; HERNANDEZ, 1997). The family Pontellidae (in the Calanoida) has large copepods, which are blue or purple (SILVA et al, 2003).
