Pleuronectiformes

ORDER PLEURONECTIFORMES

FAMILY ACHIRIDAE

Achirus novoae Cervigón 1982 [No common name]

Species was described from the freshwaters of the Orinoco River Delta (Ramos et al. 2009), and has been collected from the mouths of rivers in both Trinidad (ROM 88786, ROM 88856) and Tobago (USNM 319084). Native. Very little is known about this species. Misidentified in the past as Achirus achirus or A. lineatus. 106 mm.

Trinectes paulistanus (Miranda Ribeiro 1915) [slipper sole]

Marine, brackish (Costa de Azevedo et al. 2007) and fresh water; shallow, soft-bottomed coastal areas (Costa de Azevedo et al. 2007), hypersaline lagoons, estuaries, enters streams. Carnivore (Correa & Uieda 2007, Guedes & Araújo 2008). 180 mm.

We follow Lasso and Sánchez-Duarte (2011) in identifying the species of Trinectes in Trinidad & Tobago as T. paulistanus. T. maculatus substitutes for this species to the north, along coasts of the Gulf of Mexico.
