The Caspian seal (Pusa caspica or Phoca 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. 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.
