In Ice Age, what species is Manny?

In Ice Age, Manny is a woolly mammoth.

Manny is the central mammoth character in the 2002 animated film. His species helps establish the prehistoric setting and contrasts with Sid, a ground sloth, and Diego, a saber-toothed cat.

Woolly mammoths were Ice Age relatives of modern elephants, but they were adapted to cold climates with dense fur and substantial fat reserves. The film uses this real animal as the basis for Manny while giving him human-like speech, emotions, and family relationships.

Manny is sometimes loosely called an elephant because mammoths belong to the elephant family. The more specific canonical answer is woolly mammoth, the extinct Ice Age species represented by his shaggy coat and large tusks.
