The Cullen's Crest is a family crest that was in the movies. It wasn't in the books.
The Cullen family Crest is made up of: The hand, The Lion, and the Trefoil. The hand = Faith and Sincerity The Lion = Strength and Ferocity The Trefoil = Perpetuity
It actually doesn't say anything about a culln crest in the books but thy added it into the movie to prove they are cullens and to have a part of their family with them i guess. It doesn't exactly specify.
Its a lion.
the Cullen crest
Because the director of Twilight, Cathrine Hardwike, thought that it would be cool for the Cullens to have something that symbolises them. The guys wear the wrist band, Rosalie wears the pendant and Alice wears the choker.
Rosalie wears the Cullen crest on a chain around her neck, while Alice wears it on a small purple ribbon around her neck, in choker form.

The animal on the Heath family crest is a rooster. Google "heath family crest" to view one.
Google "Mondini Family crest" to view several websites that have images of the crest.
The Cullens each have the Cullen crest in a different form of crest and the hand symbolises faith and sencerity, the lion symbolises strentgh and ferocity and the trefoil symbolises perpetuity.
Most families never had a family crest. For those few who did, when a woman married, she joined the family of her husband and that crest would apply.
