Welcome to the Maine Mammal website. Below is a working checklist of Maine’s mammals, including those that live in the adjacent ocean. For more information about a particular species, click on the link under the heading “common name”, and you will be taken to a page for the order that includes that species.

How to contribute to this website: Please e-mail corrections and updates to or send them to the address at the top of this page. Photographs are encouraged. Thank you.

A little work by each of us will save a lot of work for all of us.
