White Grouper

Descrizione

Epinephelus aeneus, commonly known as the White Grouper or Cernia bianca, is a medium to large-sized marine fish belonging to the family Serranidae. It is a commercially important species, recognized for its distinctive coloration and robust body. This species is a protogynous hermaphrodite, meaning individuals mature as females and later transition to males. They are generally solitary but may aggregate during spawning periods. Their predatory nature makes them a significant component of their benthic ecosystems.
