  2. Bony Fishes Classification • Kingdom: Animalia (Animal) • Phylum: Chordata (Chordate) • Sub Phylum: Vertebrata (Vertebrate) • Infra Phylum: Gnathostomata (Has A Jaw) • Class: Osteichthyes (Bony Fishes)

  3. Characteristics of Osteichthyes • Breathe with gills. • Gills are covered by a membrane called operculum. • Use fins to swim… free swimming organisms are called nekton.

  4. Bony Fish Physiology • Ecotothermic – body temperature is determined by environmental temperature. • Lower Temps = Low Metabolism • Use Swim Bladder to change buoyancy.

  5. Bony Fish Reproduction • Reproduction called spawning. • Most fertilization is external.

  6. Bony Fish Development • Life Cycle Has 5 Major Stages • 1. Egg Stage • 2. Larval Stage • 3. Pre-Juvenile Stage • 4. Juvenile Stage • 5. Adult Stage
