The Southern Right Whale (Eubalaena Australis)
This is a cetaceous that has dwelled the planet for at least 55 million years. The adult whale can reach a length of 12 to 16 meters, and weigh between 50 and 55 tons. Its head occupies almost one quarter of the total length of the body and, in some parts, it is covered with callosities where a great deal of parasite crustaceans take shelter.
This whale has a calf every three years. Gestation takes twelve months and the calf is breast-fed for two years.
Each year, around 600 specimens visit our shores between May and December, although the population of the Valdés Peninsula area is estimated to include over 1200 animals. Their presence in our waters attracts around 50 thousand people from all over the world each season.
South American Sea Lion
This is a pinniped (from the family of the otariidae) which moves along the ground using its front and back flippers. The male can reach a length of 2.3 meters and a weight of 350 kilograms. This species may be seen all year round in the Valdés Peninsula.
The largest continental colony of this sea bird outside Antarctica is located in our zone, lodging over 500 thousand birds from September to mid April.
Along the entire Patagonian shore, several species of dolphins (cetaceans) may be watched. The bottle-nosed dolphin is the most characteristic in the southern hemisphere and it stands out for the black and white contrast of its body.
These mammals (cetaceans), unlike the whale, have powerful teeth. They can reach between 8 and 9.5 meters of length and weigh between 5 and 9 tons. They may be watched mainly from February to April and from October to November.
Southern Elephant Seals
The only continental colony of this seal species is found here in the Valdes Peninsula. Each year some 9,600 newborns are received by these coasts. During the reproductive season there are more than 20,000 Southern Elephant Seals along the Peninsula.
