How many baby Caspian seals are in a litter?
A Caspian seal (Phoca caspica) usually gives birth to around 1 babies.
Each of those little ones spend around 334 days as a fetus before they are released into the wild. Upon birth, they weight 4.18 kg (9.22 lbs) and measure 6.9 cm (0′ 3″). They are a member of the Phocidae family (genus: Phoca). An adult Caspian seal grows up to a size of 1.41 meter (4′ 8″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
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.
