[3.5] Animal Companion question.

[Ketiara]

So it says in PH p. 35 and 36. That a druid can choose an animal companion from the following lists. The list is rather limited and I cant find anything that says you can look beyond these lists.
However when I read different druidguides it keep mentioning that I should choose fleshraker as my companion or others ofcourse.
Where does it say that I can look for alternate (apart from the ones in ph) companions?

There isn't really a consolidated list anywhere in the books that I know of. Generally, if an animal is being added to the animal companion list, it's actually mentioned in the monster entry. For example if you were to look up fleshraker, it would say that they can be a druid's animal companion at level-3 or something like that. You might be able to find a list that someone's put together poking around google.

[Biffoniacus_Furiou]

The most complete list that I've seen is in PH2, in a sidebar on the Druid section. Note that this list may contain typos, and that the individual monster entries in their respective books should have a more complete text entry for what level of Druid may recruit it.

I think this should be pretty close to comprehensive:
