red drum
Red Drum
  • NC State fish, commonly sold as redfish, puppy drum, channel bass, or spottail drum
    • Ocellus – eye-like spots used as a false eye to avoid head attacks by predators

  • One of the most commonly caught nearshore marine fishes
  • Possess a convex caudal fin

Sciaenidae thru Pomacentridae

weakfish cynoscion regalis
Weakfish (Cynoscion regalis)
  • Found in coastal waters and usually possess 2 large canine teeth in the upper jaw
    • Spawning occurs nearshore in estuarine waters

Sciaenidae thru Pomacentridae

otoliths
Otoliths
  • Otoliths are the inner ear bones of fishes which are used for hearing, equilibrium and balance

family ephippidae spadefish
Family Ephippidae (Spadefish)
  • Spinous and soft dorsal are separate
  • Adults associate in large aggregations in areas with vertical relief
  • Characterized by a blunt face and small mouth
    • Highly compressed body

atlantic spadefish chaetodipterus faber
Atlantic Spadefish (Chaetodipterus faber)

Sciaenidae thru Pomacentridae

family chaetodontidae pomacanthidae
Both families are extremely common on coral reefs

Acutely compressed bodies, large dorsal and anal fins

Colorful, with striking patterns of stripes and spots

Both families have remarkable feeding habits

Small protractile mouths with tiny teeth

Feed at various depths on zooplankton, coral polyps, sponges, and polychaetes
