Bones: water living changes bones

February 19, 2010 by Carolyn Kraft Leave a Comment

Here I thought that reading the section on bones in the Encyclopedia of Marine Mammals would bore me to tears. And well let’s just be honest, some of it was definitely sleep inducing. Until I came to the part about “two very different trends in bone architecture and histology.” OK, stay with me now, I… [read more]

Bearded Seals: sweet whiskers

January 27, 2010 by Carolyn Kraft 4 Comments

The bearded seal or Erignathus barbatus is the Santa Claus of seals with fabulously long whiskers that curl a bit when dry. And how fitting since they live not far from the North Pole at the edge of the sea ice that extends in all directions from this northern most point. But the whiskers of… [read more]

Barnacles: living on a whale

January 22, 2010 by Carolyn Kraft Leave a Comment

Barnacles seem to have quite the life indeed. These crustaceans represent a diverse group that includes more than 1,000 species. Some of these barnacles have adapted to living on marine mammals and tend to hang out on some of the baleen whales. My guess is that it’s easier to live and stay attached to a… [read more]

Australian sea lion

January 4, 2010 by Carolyn Kraft 2 Comments

What better way to kick off 2010 than with a post about the Australian sea lion, “one of the world’s rarest and most unusual seals?” A direct quote from the Encyclopedia of Marine Mammals.

Arctic Marine Mammals

December 24, 2009 by Carolyn Kraft 1 Comment

What better way to celebrate the holiday season than with a post about all the fabulous marine mammals hanging out near the North Pole? The Arctic hosts a variety of marine mammals including eight species of pinnipeds (several seals, walruses), three cetaceans (bowhead, beluga and narwhal whales) and one fissiped (polar bears).

Antarctic Fur Seals

November 24, 2009 by Carolyn Kraft Leave a Comment

Antarctic fur seals or Acrtocephalus gazella hang out in intense cold around islands in the South Atlantic and Indian Oceans near Antarctica.
