What is the maximal age a Caspian seal reaches?
An adult Caspian seal (Phoca caspica) usually gets as old as 50 years.
Caspian seals are around 334 days in the womb of their mother. When born, they weight 4.18 kg (9.22 lbs) and measure 2.37 meter (7′ 10″). As a member of the Phocidae family (genus: Phoca), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 1.41 meter (4′ 8″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The Caspian seal (Pusa caspica) is one of the smallest members of the earless seal family and unique in that it is found exclusively in the brackish Caspian Sea. They are found not only along the shorelines, but also on the many rocky islands and floating blocks of ice that dot the Caspian Sea. In winter, and cooler parts of the spring and autumn season, these marine mammals populate the Northern Caspian. As the ice melts in the warmer season, they can be found on the mouths of the Volga and Ural Rivers, as well as the southern latitudes of the Caspian where cooler waters can be found due to greater depth.Evidence suggests the seals are descended from Arctic ringed seals that reached the area from the north during an earlier part of the Quaternary period and became isolated in the landlocked Caspian Sea when continental ice sheets melted.
