AMPULLAE OF LORENZINI

Sharks have sensory organs around their snouts that are sensitive to electrical fields.
The ampullae help sharks hunt by sensing the electrical activity in their prey’s body (like a heartbeat).
 

lateral line


The lateral line system of sharks extends from the head to their tails. 

Sharks use the lateral lines to detect patterns in the water that suggests there is an injured or distressed animal in that direction. Sharks also combine lateral lines with their own swimming patterns to create an echolocation field!

Glow in the Dark Sharks

certain sharks can glow in the dark, like this swell shark (Photo via Gruber et al.) that emits a green color when in the deep, dark ocean. other species, like some lanternsharks, have spines that light up to warn predators to stay away. deep sea sharks can also emit this glowing light from thousands of tiny photogenic organs – called photophores – to CAMOUFLAGE itself... and it may be used as a type of communication between the sharks, too!
