Distribution
These dolphins live in bodies of water that have a warm temperature. The Long – Beaked Common Dolphin is found close to the shallow waters. The Short – Beaked Common Dolphin though tends to be in deeper waters up to 590 feet. They tend to do well in many areas as long as they have enough food and warm enough water.
These dolphins don’t migrate like so many other species do. However, they will move around if necessary to find food and when there is unusually cold waters. They often do return to their home range though as soon as possible.
Behavior
The Common Dolphin is very social, and they live in large groups called pods. The number in a pod can be several hundred or it can be in the thousands. The largest ones number over 10,000. They have a very complex hierarchy that keeps them orderly and they tend to create subgroups based on age and other factors.
This dolphin species has been seen taking part in a variety of different behaviors. They include somersaults, pitch poling, breaching, and bow riding. They are very active and they seem to be able to move through the water almost effortlessly. They are also playful so they spend time teasing each other.
Touch and echolocation are big parts of their social interactions with each other. They seem to thrive on the connections they have with each other. Vocalizations including whistling, whining, and clicking are very common. The dialogue though can be different based on the pod and that is a very interesting element of their overall behaviors.
