Turtles are not the only animals that live in the ocean. There are many animals that also live in the ocean and swim in the water. These include mammals, fish and in certain areas of the world, even birds. There are a few animals that travel along the same lines as turtles as they migrate through the waters. Let’s take a look at a few of the turtle’s friends in the waters.
A popular mammal is the bottlenose dolphin. This playful animal is often seen jumping out of the water and riding over the surface of the waves. They are also usually found in small to large groups. Since they are mammals they must surface to breathe since they do not have lungs like a fish does. Whales are also mammals which must rise to the surface of the water in order to obtain oxygen, but some species are able to stay underwater for up to 90 minutes at a time.
Many whales prefer colder waters, but they do move great distances and can be seen off the coastlines of some countries. There are species of turtles that also prefer colder waters and can be found off the coast in the same waters where the whales can sometimes be seen. In some parts of the world you can find penguins and turtles in the same ocean, for instance, in the Galapagos islands you can find the Galapagos green turtle and the Galapagos penguin.
There are several species of fish in the ocean some of which will overlap in habitat with the turtles. Some species of fish are more tropical than others and are therefore found in warmer waters where there may also be more tropical species of turtle present. Loggerhead turtles and green turtles are found off the coast of Florida where they are found along with many types of fish. Such fish include for example, the barracuda, blue marlin, shad, perch, flounder and grouper, along with various species of catfish. Sharks are also commonly found including the blacktip shark.
Most of the time when we think of other animals found where turtles are found, we do think of these large animals such as whales, dolphins, and fish. However, there are also many smaller organisms that also co-occur with turtles, such as krill. Krill are small organisms which include tiny crustaceans that live in the ocean. Turtles may feed on these animals.
Aside from this, there are commensals which are organisms that live on the shell of the turtle. These include algae and barnacles. The barnacles that live on turtles are very specialized to do so. They are often found on green turtles and loggerhead turtles. Platy lepadid barnacles do not injure the turtle in anyway but simply live on the shell of the turtle and benefit from a free ride through the sea. Some animals are parasites on turtles. For example, marine leeches have a strong sucker that can suck blood and often attach to areas where the skin is not as thick, so around the eyes for instance. They can weaken a turtle because they suck on its blood.
