  • Paired fins
  • Paired nostrils
  • Scales
  • Two-chambered hearts
  • Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone.
  • Well developed jaws and paired fins

Sharks are distinguished by such features as:
    • The number of gill slits.
    • The number and type of fins.
    • The type of teeth.
    • The size of their jaws.
    • Body shape.
    • Their activity at night.
    • An elongated, toothed snout used for slashing the fish that they eat, as seen in sawsharks.
    • Teeth used for grasping and crushing shellfish, a characteristic of bullhead sharks.
    • A whisker-like organ named barbels that help sharks find food, a characteristic of carpet sharks.
    • A long snout (or nose-like area), characteristic of groundsharks.
    Rays:
    • Developed larger pectoral fins.
    • Many have a venomous barb on the end of their tail used to avoid predation.

  • Shark eggs are fertilized internally through claspers found on male sharks.
  • Three types of gestation
    • Oviparous: eggs laid outside of mother in thick mucus layer
    • Ovoviviparous: retention of the eggs within the uterus but only the eggs nourishes the embryo.
    • Viviparous: placental formation in the uterus.
