What is a Dolphin?

A dolphin is a sea mammal closely related to the porpoise and whale. There are 40 different species of dolphins, which can be found in all corners of the globe. All dolphins have thick layers of blubber under their skin that help them stay warm even when it’s cold outside.

Dolphins live in the ocean in various habitats, like in shallow water near the coast or far out on the open ocean. They can also be found living as close to shore as possible (called coastal dolphins) and they have been spotted from time to time even swimming up rivers!

According to, “Orcas are the only dolphins which live in the Arctic and Antarctic. Their large size means that they have more protection against the harsh cold of the freezing seas. Most dolphins prefer tropical and temperate waters as they are warm-blooded mammals and so it is easier for them to regulate their body temperature in these environments.”

Dolphins are social animals who live together in pods of between five and fifty members. They are quite intelligent and have excellent sensory organs that can pick up subtle vibrations in the water.

Dolphins communicate with each other by means of clicks, whistles, and body language, but they also use echolocation to find food at night or when it’s dark out!

How can you help protect them?

There are a number of ways you can help protect dolphins by being aware of the many threats they face.

  • You should never feed wild dolphins, as it teaches them that people are a source of food.
  • Be aware of the risk to dolphins in fishing gear, and avoid buying any type of fish caught using dolphin-unfriendly nets or methods such as longlining.
  • Avoid products made from plastic bags which can be mistaken for food and ingested by sea life.
  • Leave wild animals alone so they’re not disturbed while enjoying the natural world.
  • Educate yourself about the threats to their habitat and how you can reduce your footprint so they’ll have somewhere safe to swim in the future.
