Dolphins are my daugters favourite ,

Dolphins live in small groups called pods, these pods can be quite fluid and dolphins can be seen interacting with dolphins from other pods from time to time. If another dolphin is drowning, other dolphins will come to it's aid, supporting it with their bodies so it's blowhole is above the water allowing it to breathe. Dolphins main predators are sharks and unfortunately man, through direct killing for food,netting, pollution, and fishing. 


Dolphins can gang up on a shark and kill it by ramming the shark's gills with their snout. Dolphins spend a large part of their day looking for food, or actually feeding. They may either hunt alone, or together as a pod. They use their echolocation (sonar system) to locate fish by sending out a stream of pulses and clicks. Dolphins communicate with each other by whistling or body language. When a baby is first born, a mother dolphin will whistle to it constantly, imprinting her sound on the baby so it will recognize her, and the baby learns to develop its own signature whistle. 


It is thought that each dolphin has its own individual signature whistle, just like a name.
