2 Sphyraenidae Characteristics
Elongated pike-like bodies, superior jaws Traits: Sphyraenidae, Blenniidae, & Gobiidae

3 Sphyraenids Guaguanche Sphyraenidae, Blenniidae, & Gobiidae

4 Great Barracuda Apex predators
Can reach 6ft. and have been known to attack divers Attacks may be due to reflective metal on divers Sphyraenidae, Blenniidae, & Gobiidae

5 Southern stargazer buried in the sand
Family Uranoscopidae Southern stargazer Astroscopus y-graecum Northern stargazer Astroscopus guttatus Southern stargazer buried in the sand Sphyraenidae, Blenniidae, & Gobiidae

6 Uranoscopidae Characteristics
Large, cuboidal head Mouth strongly oblique Breathes through nostrils Eyes can protrude a short distance Can create electrical currents 50 volts Some species attract prey using small vermiform filament on floor of mouth Sphyraenidae, Blenniidae, & Gobiidae

7 North vs. South Southern Northern Sphyraenidae, Blenniidae, & Gobiidae

8 Family Blenniidae Blennies Common species:
Striped Blenny (Chasmodes bosquianus) Crested Blenny (Hypleurochilus geminatus) Feather Blenny (Hypsoblennius hentzi) Sphyraenidae, Blenniidae, & Gobiidae

9 Blenniidae Characteristics
Important on rocky inshore habitats in the tropics and subtropics (benthic) Also, found in fouling habitats Seaweed Blenny Sphyraenidae, Blenniidae, & Gobiidae

10 Combtooth Blennies Sphyraenidae, Blenniidae, & Gobiidae

11 Blennies “Combtooth” stems from the numerous closely packed teeth in the jaw Blunt heads are topped with cirri Cirri are chemosensory in nature and used in sex recognition Cirri Sphyraenidae, Blenniidae, & Gobiidae

12 Family Gobiidae Gobies Common species:
Darter Goby (Gobionellus boleosoma) Clown Goby (Microgobius gulosus) Sphyraenidae, Blenniidae, & Gobiidae

13 Gobiidae Characteristics
Approximately 1,875 spp., is only slightly smaller than Cyprinidae Found worldwide in both fresh and saltwater Recognizable by several characteristics: Sphyraenidae, Blenniidae, & Gobiidae

14 Gobies have a remarkable ability to adapt to environments inaccessible to most fishes
Mud Flats Some species have the ability to breathe air and make short walks to other habitats Longjaw Mudsucker Invertebrate Burrows Sponges, Sea Urchins, Hard and soft corals Mangrove Swamps Mudskippers Freshwater on oceanic islands
