Vary rarely do you see them from the shore but they are out there in the Atlantic ocean surrounding the island. The waters are cold to moderate which make them ideal for the bottle nosed dolphin. Some species are resident whilst others are just passing by, due to the placement of the Canary Islands.
Bottlenose dolphins live in groups typically of 10–30 members, called pods, but group size varies from single individuals up to more than 1,000. Their diets consist mainly of forage fish. Dolphins often work as a team to harvest fish schools, but they also hunt individually. Dolphins search for prey primarily using echolocation, which is similar to sonar. They emit clicking sounds and listen for the return echos to determine the location and shape of nearby items, including potential prey. Bottlenose dolphins also use sound for communication, including squeaks and whistles emitted from the blowhole and sounds emitted through body movements, such as leaping from the water and slapping their tails on the water surface.
There are various excursions on Lanzarote that take you out to see the dolphins but you will be very lucky if you do actually see them
