Sharks are fish. Fish swim in 'schools'. Whales and dolphins are mammals. These swim in 'pods'.
Fish swim in schools. Other marine species, like whales and dolphins (which are mammals) swim in "pods"
There is no certain leader. They swim in schools because its hard for a bigger fish to catch all then just one.
Most dolphins swim in groups, as it gives them many strengths. They can watch each other's backs for danger, scout for food and assist each other in hunting, and scare off predators with their numbers. Dolphins that are not members of a pack will not last long.
Swim
Avon in Monmouth County, New Jersey has had sighting of dolphins. A swimmer could swim in the sea there to swim with the dolphins.
if there is only one dolphin the shark will probably harm it but if its a pack the dolphins will all attack it by hitting and jabbing the shark with its baseball hard noses then will swim away
dolphins swim in pods to protect themselves and to catch food
Are we allowed to swim with dolphins at curious Cove
What dose it mean when dolphins swim to shore
Dolphins can swim up to 260 miles below the surface.
call me crazy but I have always been under the impression that fish travel in schools and herds are reserved for mammals on the ground ..........just a thought
