I don't think so, but let's give them an "as characters" paragraph. Favored class wizard?
Updated, with an "as characters" section. Do the domains and bonus languages look OK?
The languages and domains are fine, except I don't like Travel for them. I'd prefer Knowledge, Protection or Weather.
Hmm, going by the original description they should only bite when they lack weapons. Their bite is also pretty feeble, so may be a secondary-only attack like the SRD Camel's.
Oh, and we should make clear that they're herbivores. I'd change the first paragraph to:Flawder are peaceful herbivores who roam the floor of seas and large lakes. They live in small nomadic tribes, each tribe's shells has a distinctive pattern and coloration.Apart from that I don't see anything worth fussing with. You know me, I don't like to fuss unnecessarily.

My unfussy self still thinks that "each tribe's shells has a distinctive pattern and coloration." is a better wording than "each with shells of a different, distinctive pattern and coloration". It's just clearer that the whole tribe has a particular shell pattern.
They live in small nomadic tribes, each tribe's shells has a distinctive pattern and coloration.
