The acid panther lives in the swamp regions of the world, and literally have battery acid for blood and saliva.
The Beetle thingy is a giant sized beetle of about 8 feet or so and has the ability to spin webs and eats the flesh of its victims while keeping them alive, and then feeds the rest to their larva and such. It's pretty interesting. The beetles live in the acritc region and is the most dangerous opponent for the vortek race.
I am also coming up with a frog type of species that have the ability to use fire from its mouth.
