Atherinidae thru Syngnathidae 5 Schooling Behavior
6
Atherinidae thru Syngnathidae 6 How do fishes school? Most schooling fishes depend on vision for group cohesion oEvidence? Lateral line is integral in spacing and coordinating synchronized movements
7
Atherinidae thru Syngnathidae 7 Why do fish school? Hydrodynamic efficiency Increased efficiency in locating prey Reproduction Reduced predation risk oDilution effect oConfusion effect
8
Atherinidae thru Syngnathidae 8 Family Holocentridae Squirrelfishes Common species: oSquirrelfish (Holocentrus adscensionis) oBlackbar Soldierfish (Myripristis jacobus) Holocentrus adscensionis
9
Atherinidae thru Syngnathidae 9 Holocentridae Characteristics Nocturnal, live on coral reefs and rocky shores Frequent vocalizations used for communication Myripristis jacobus

12
Atherinidae thru Syngnathidae 12 Fistulariidae Characteristics Share many similar characteristics with the Aulostomids (Trumpetfishes) Long snout with a large mouth at the end oUsed as a pipette-slurp-gun to suck up prey Found on reefs as lie and wait predators odorsal scutes, and lacks chin barbel
13
Atherinidae thru Syngnathidae 13 Family Aulostomidae Trumpetfishes Local species oTrumpetfish (Aulostomus maculatus)
14
Atherinidae thru Syngnathidae 14 Aulostomidae Characteristics Rounded caudal fin, ctenoid scales, and barbels on the chin Masters of disguise, approaches prey and feeds in manner similar to Fistulariids
