If you go under Information>Creatu Search you can enter all the parameters for searching a name. Then you will have to manually go through each species to find the name, which is quite time consuming and why some players pay others to do it ^^
Ah, you don't put in the name during search - that's what you have to find. Basically, enter in the species, arrange them by alphabetical order, and go through the list of names until you find the name you're looking for. Then you repeat that for every single species. Hence why some name searches can take a long time.
