Mother sea otter with rare twin baby pups, presumed to have been born just one or two days earlier on June 23-24, 2013. Photo taken 24 June 2013, Morro Bay, CA. AKA Southern sea otter and California sea otter, Subspecies E. l. nereis, Coast of Central California.

Here is a Wired Magazine article covering my photos of the twin sea otter pups - www.wired.com/wiredscience/2013/06/rare-sea-otter-twins/

AOL's Huffington Post also covered my sea otter twins story on 7/1/2013.. www.huffingtonpost.com/2013/07/01/sea-otter-twins-born-ca...

Wiki en.wiki.x.io/wiki/Sea_otter says “Birth usually takes place in the water and typically produces a single pup weighing 1.4 to 2.3 kg (3 to 5 lb). Twins occur in 2% of births; however, usually only one pup survives. At birth, the eyes are open, ten teeth are visible, and the pup has a thick coat of baby fur. Mothers have been observed to lick and fluff a newborn for hours; after grooming, the pup's fur retains so much air, the pup floats like a cork and cannot dive. The fluffy baby fur is replaced by adult fur after about 13 weeks.”

animals.pawnation.com/lifespan-marine-otter-1756.html says “Female sea otters give birth to their pups under water. In most cases only one pup is born; rarely, a female sea otter gives birth to twins. Because a mother otter cannot care for two pups, one of the twins will die. For the first couple months of an otter pup’s life, he lives on his mother’s belly. She protects the pup from predators, grooms him and feeds him. Male otters do not assist in care of the young.”

marinebio.org/species.asp?id=157 says “Typically, there is only one pup per pregnancy. On the rare occasion of twins, the mother can only raise one. Her food requirements are large, and so are the pups. The mother would have a hard time getting enough food for two additional mouths. Unlike the river otter, the sea otter mother is the pup's cradle, protection, and home for the first months of its life. The mother would only have room for one pup.”
