media type="custom" key="650195"**About Dolphins** Dolphins are mammals, not fish. They are warm blooded like man, and give birth to one baby called a calf at a time. At birth a bottlenose dolphin calf is about 90-130 cms long and will grow to approx. 4 metres, living up to 40 years.They are highly sociable animals, living in pods which are fairly fluid, with dolphins from other pods interacting with eachother from time to time.

With the help of several beautiful bottlenose dolphins we can see how well the dolphin body is adapted for their life in the ocean

Dolphins use their powerful tail flukes in an up and down motion to move through the water. They also use their tails when hunting, hitting a fleeing fish up into the air with their tail, stunning it, then scooping the fish up when it falls back into the water. A dolphin slapping its tail on the water in the wild may be a sign of annoyance, or a warning to other dolphins of danger.

The baby will however stay with its mother for between 3-6 years, during which time it learns all about feeding techniques, social interaction and group foraging. Females are likely to stay within the family pod with their mother and sisters, though males will leave and form associations with other males. Dolphins have defined home ranges, an area in which they will roam and feed. Though 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 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 eachother by whistling or body language. When a baby is first born, some dolphin research suggests 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.
