Abudefduf saxatilis and Diplodus argenteus were the main species, both for density and biomass, showing great plasticity, inhabiting different reef environments and feeding on a wide range of resources (Carvalho-Filho, 1999; Harmelin-Vivien, 2002; Ferreira et al., 2004).

In contrast,
Abudefduf saxatilis, with 18 haplotypes, had only 31% of the individuals in the most abundant haplotype class (table 2).

Seventeen mature Abudefduf saxatilis females were collected with hook and bait and killed with benzocaine at 100 ppm for 20 min, animals were then injected with formalin at 10%.
Abudefduf saxatilis may be sexed by its color and behavior (males are bluish and guard a territory).
Abudefduf saxatilis and Stegastes fuscus behave more similarly than Chromis multilineata.
Female Abudefduf saxatilis presented multiple spawning with oocytes ready to be delivered and atretic follicles in their ovaries in the 17 collected females.
Parental care in Abudefduf saxatilis and Stegastes fuscus lasts until the larvae hatch, parents defend offspring from predators, fan and clean the eggs.
Some common visually oriented egg predators found in Sao Paulo rocky shores are Abudefduf saxatilis, Chaetodon striatus and Diplodus argenteus (Randall, 1967), amid many others.
