Swimming Ocean Shark

A large shark glides toward the left side of the frame with a smiling mouth expression. Its prominent dorsal fin extends from its upper back, while visible gill slits sit along the side of its body.

Facts About Shark Biology

Sharks do not possess bony skeletons like most fish species; instead, their bodies are supported entirely by flexible cartilage. Gill slits allow seawater to pass through internal breathing structures so the animal can absorb oxygen while moving forward. Many shark species possess an exceptional sense of smell that detects chemical signals miles away.

Natural Colors of Ocean Sharks

  • Shark upper body: slate gray, bluish gray, or bronze
  • Shark underside belly: pale white or light gray
  • Shark dorsal fin tip: charcoal gray or black
  • Shark eyes: dark brown or solid black
Questions and answers

Questions and Answers

How do gill slits help sharks breathe underwater?
As a shark swims forward, water enters its mouth and exits through gill slits, where microscopic blood vessels absorb dissolved oxygen.
Do all shark species need to swim constantly?
Some species must keep swimming to push water across their gills, while others rest on the ocean floor and pump water manually.
What is shark cartilage made of?
Cartilage is a tough, elastic tissue similar to the flexible material found in human ears and nose structures.
