  • The Bottlenose dolphin

    19, Jul 2014 in Dolphinwatching

    The Bottlenose Dolphin (Tursiops truncatus) is a species of cetaceans that can be spotted in our Marine Life Watching Tours.



    This specie has a big range of sizes, shapes, and colors depending on its habitat. It can weigh from 150 to 600 kg and it can measure from 2 to 4 meters length. Its longevity is about 30 to 40 years.

    The Bottlenose Dolphin has a well defined nose and pointy fins. Its back is dark gray, fading to white on its lower jaw and belly. Females are smaller than the males and the juveniles show a lighter bluish coloration.



    This specie of dolphins inhabits coastal waters, although it can be seen frequently in estuaries, in temperate or tropical waters of Atlantic, Pacific and Indic Ocean. In Portugal can be seen along the entire mainland coast and also in the Archipelagos of Azores and Madeira.



    This efficient predator takes advantage of echolocation to determine the position of the preys which include fish, cephalopods and crustaceans. Although they have complicated hunting strategies, due to this technique the Bottlenose Dolphin is able to identify a prey miles away.

    This specie reproduction is mainly from April to September, but it can be seen breeding all year around. Each female has only one calf in each 2 to 3 years. When the females give birth they are helped by other females, protecting each other and the calf from potential shark attacks since these may be attracted by the blood. These females also cooperate to help the calf to come out pulling it from the tail and pushing it to the surface in order to breathe.



    Bottlenose dolphins usually live in groups consisting of females and younglings, while males form alliances, and can be found with other dolphin species. This is an animal that shows some curiosity when it encounters humans and can be found sometimes playing with boats in our Dolphin Watching Boat tours, side by side with common dolphins swimming at the bow of the boat.

  • The Short-beaked Common Dolphin

    13, Jul 2014 in Dolphinwatching



    The Short-Beaked Common Dolphin (Delphinus delphis) is one of the most frequent observed cetaceans in our dolphin watching Tours.

    In this specie we can find individuals with lengths varying from 1,6 to 2,4 m and can reach 100 to 200 kg in weight, in which the females are slightly smaller than the males.

    The short-beaked common dolphin feeds on a great variety of fishes, like sardines, small mackerel, hake or anchovies, and also cephalopods as octopus, squids and cuttlefish.

    It can be found in tropical and temperate waters from the entire world, and in Portugal it is present in the continent, and also in the archipelagos of Madeira and Azores.



    They reproduce during the entire year, with a higher frequency during spring and summer, mating a little over a year and both males and females have longevity of around 50 years.

    Being social animals, they form groups of dozens till thousands of individuals, dividing themselves according to their gender or sexual maturity. Being that they can also be found together with other species of dolphins such as striped dolphin (Stenella coeruleoalba) and the common bottlenose dolphin (Tursiops truncatus).



    They are very active and acrobatic animals, performing aerial jumps while swimming. Being able to move at a velocity of 29 miles/hour, they are very fast while pursuing their preys or moving between feeding grounds.

    During our Marine Wildlife Tours they are often seen interacting with our boat, swimming at the bow of the boat.

    18, Apr 2013 in Dolphinwatching


    Here in the Algarve as Spring arrives and the days and waters get warmer, the sardines are also more abundant in the coastal waters. Following this pattern, the dolphins also approach the coast in search of this tasty meal.

    In our dolphin watching and marine wildlife boat trips boat the most sighted species of dolphins are:

    • Common Dolphin (Delphinus delphis),
    • Atlantic Bottlenose Dolphin (Tursiops truncatus)
