Family Gerreidae • Mojarras • Common species: • Spotfin Mojarra (Eucinostomus argenteus) Gerreidae, Haemulidae, & Sparidae
Gerreidae Characteristics • Highly protrusible jaw, compressed silvery body • Use mouth for feeding on benthic invertebrates • Passes sand out gill slits and captures prey on gill rakers • The silver jenny (Eucinostomus gula) and spotfin mojarra (Eucinostomus argenteus) are almost indistinguishable Gerreidae, Haemulidae, & Sparidae
Family Haemulidae • Grunts • Common species: • Tomtate (Haemulon aurolineatum) • White Grunt (Haemulon plumeri) • Pigfish (Orthopristis chrysoptera) Gerreidae, Haemulidae, & Sparidae
Beautiful schooling fish, usually found associated with reefs Small mouth and teeth, large molariform teeth on pharynx Haemulidae Characteristics French Grunts Gerreidae, Haemulidae, & Sparidae
Diurnal Migrations • Form diurnal aggregations on reefs and migrate to sand and grass beds to feed • Interestingly, migrations always follow the same route • Routes are not genetically inherited, but learned socially as “cultural traditions” Gerreidae, Haemulidae, & Sparidae
