Grunt Family, (Haemulidae): The fish of the Grunt or Haemulidae family are known in Mexico fishing areas as "burros."They are similar in appearance to the snappers but can be distinguished by their lack of canine and vomerine teeth and by the presence of pits on their chins.
When collected, these fish grunt audibly by rubbing together tooth plates in their throats. Most grunts are small schooling fishes that swarm over reefs during the day and move to sandy shoals at night. They feed primarily at night on benthic invertebrates such as shrimp, clams, and polychaetes worms. The stripes of juveniles are more prominent than in adults.
Globally, 137 species of grunts from 19 genera have been identified, many of them hard to differentiate. In Mexican fishing waters, there are reports that as many as 25 different kinds of grunts reside in the Sea of Cortez alone.
