As we head into the holiday season, we want to celebrate the incredible endangered animals and plants the Center for Biological Diversity -- and you, our supporters -- work so hard to protect all year.

We've come up with six unique e-cards featuring the ivory gull, gray wolf, polar bear, sea star, bearded seal and coral reefs to share with your friends, families and coworkers this year-end.

Thank you for all the support and action you've taken this year, and happy holidays from all of us at the Center.
