Dolphins are from temperate and tropical waters around the world. The first Dolphin discovered in the world was the Miocene delphinium fossil. It was around for 23 million to 16 million years. Dolphins can be found all over the world in different environments like, harbors, bays, gulfs, and estuaries, as well as nearshore coastal waters, deeper waters over the continental shelf, and even far offshore in the open ocean. There are many types of dolphins, there are like 80 billion different species. Dolphins species are orca, amazon river, striped, baiji, etc. All of the species live about 45 to 50 years; the female dolphins tend to live more than the males. Female Bottle-noses live up to 60 or more years. Dolphins eat fish, squid, shrimps, jellyfish and octopuses. It also depends on what type of species the dolphin is. Dolphins have many predators. Dolphins predators are tiger sharks, dusky sharks, etc. But that isn’t the biggest threat to dolphins. The most threat to dolphins is entanglement and fishing gear. This is a threat because it could drown the dolphins immediately if its gear is large or heavy.  Another threat for dolphins is underwater noise pollution. It’s important because noise can travel long distances underwater, blanketing large areas, and potentially preventing marine animals from hearing their prey or predators, finding their way, or connecting with mates, group members, or their young. Dolphins can ignore predators by using their intelligence, incredible speed, communication, echolocation, and traveling in pods. In fact, dolphins are able to scare off sharks just by swimming in large groups. This means dolphins aren’t scared of their predators at all if they are together.  Dolphins are really smart and friendly towards others that aren’t their predator or prey.
