Dolphins are known to favour the channel between Mallorca and Menorca, If you are lucky enough to see these beautiful creatures, enjoy every second and remember that these animals always control any encounter. If whilst on holiday in Menorca you are fortunate enough to have the joy of such an encounter the WDCS would appreciate a sighting report, together with as much information on weather conditions as you can provide. using the link at the bottom of this page

These creatures are marine cetacean mammal of the order cetacea. This order also includes whales, and porpoises. Whales are actually just large dolphins of over five meters in length.

Delphines, as the Spanish call them and the Porpoise are two different types of mammals, the former are larger, more streamlined and acrobatic whereas Porpoises are smaller and stockier with triangular dorsal fins or no dorsal fins at all. They have a rounded snouts and generally travel in small groups. Porpoises also use "echolocation" to find food and for navigation but unlike the Dolphin clicks their communications are at frequencies beyond the range of human hearing.

These marine mammals inhabit all of the World's Oceans and Seas. They can also be found in some large river systems. These animals are carnivores and their diets vary according to their habitat but commonly consist of either fish or squid, octopus, cuttlefish, crabs, shrimps and lobsters.

Interesting Facts

They never sleep!

This is not actually true but they cannot sleep in the way other mammals do because they have to remain conscious in order to breath. Thus they cannot go into a full deep sleep. If they were to sleep like other aminals they would suffocate.

It has been established from studies using EEG readings that they have evolved a technique whereby half of their brain sleep at any one time. It would there appear that they "sleep" for about eight hours day using this technique.

They are long lived

We still know relatively little about these beautiful creatures however their average life span has been studied at some length The average age can be calculated from the Annual Survival Rate (the ASR percentage of animals alive at a certain point, that are still alive one year later). Studies in America at Sarasota Bay have shown the ASR to be about 0.961 giving a life expectancy of about 25 years. However studies in the Indian/Banana River area, the ASR is between 0.908 and 0.931. This would indicate a life expectancy of between 10.3and 14 years. It therefore appears that the life expectancy differs per region and as the maximum age for the bottlenose is between 40 and 50 years, from species to species
