|
|
They will shock other animals.

|
They use it to hide in the seaweed.
|
|
|
They use it to protect them from becoming another animal’s prey. They freeze when they sense an electrical signal from a predator.

Detailed explanation-1: -A shark has special receptors located around the head that detect electric fields. These receptors can help a shark find a fish hidden under the sand by detecting its heartbeat. A shark also uses this sense to position its head and mouth when moving in for the final attack.
Detailed explanation-2: -Electroreception helps sharks locate prey just before they bite it, as their eyes cannot see the area near their mouths. Some sharks use this sense to locate buried prey.
Detailed explanation-3: -The laterally expanded cephalofoil allows hammerheads to possess longer ampullae of Lorenzini tubules which might confer greater sensitivity to weak electric fields.
Detailed explanation-4: -The electric field sensors of sharks are called the ampullae of Lorenzini. They consist of electroreceptor cells connected to the seawater by pores on their snouts and other zones of the head.
