luniscutis occurs along the eastern coast of
South America from the Guianas to Brazil, and may
reach a maximum length of 1.2 m (Figueiredo &
Menezes 1978). Like the other species, it occupies
marine and brackish environments (Marceniuk &
Menezes 2007). Knowledge about this species is also
very sparse (Mishima & Tanji 1982, Azevedo et
al. 1999). The family Ariidae includes the catfishes,
marine and brackish water leather fishes (Figueiredo
& Menezes 1978). The family has a wide distribution
in tropical and temperate waters, and its members
occur near the coast, in estuaries and inland waters;
few are strictly marine (Marceniuk & Menezes 2007).
Reproduction: The catfishes seek
out river mouths and lagoons during the spawning period
(Figueiredo & Menezes 1978). The reproduction
occurs normally, in the warmer months of the year
or during the rainy period, when there is a major
uptake from rivers (Mazzoni et al. 2000, Gomes &
Araújo 2004, Fávaro et al. 2005). Diet:
They have a wide feeding spectrum, which may vary
during their ontogenetic development, with the diet
mostly constituted of detritus, decapods, fish, polychaetes
and bivalves (Espírito Santo & Isaac 1999).
The first thumbnail specimen was captured in Santos,
Brazil in May 2011.
America: Atlantic coastal rivers of South
America from French Guiana to southern Brazil.
