Fish with cartilage instead of bones.Cartilage: Strong tissue that is flexible. Protects and supports bones and joints. Human noses and ears are made from cartilage.Dermal Denticle: Shark teeth which are not made of bone.Enamel: Hard protective layer around bone or cartilage. Human teeth are covered in enamel. It is the hardest substance in a human body.Buccal Ventilation: A method some sharks use to breathe. They use muscles in their cheeks to draw water in and push it past gills, which take in oxygen from the water. Sharks that use this can breathe while not moving.Ram Ventilation: A method some sharks use to breathe while swimming with their mouths open, so water rushes over their gills.Electroreception: The ability in animals to sense electrical currents and fields.Ichthyologist: A scientist who studies fish.Ampullae of Lorenzini: Jelly-filled sacs (pores) that allow a shark to sense the electrical field and find food using electrical currents.Cephalization: When sensory organs are concentrated on the font of the body or face.Lateral Line: A line down the center of fish on both sides containing sensory organs. Fish use the lateral line to feel things around them.Sensitive: Being able to feel slight differences, changes, or influences.
