Found on rocky and sandy bottoms in coastal waters (Ref. 53324). Oviparous with low batch fecundity (Ref. 53324). "We frequently catch P. semifasciata off the Rio de Janeiro coast. I have personally seen fish of 24 kg, with fish in the 12-18 kg range being fairly common (Capt. Eduardo Baumeier, pers. comm., 2001)." Ref. 27569 gave 10 kg as maximum weight.
