"Animals" consists of all non-plant living organisms. Fish and insects are types of animals, though I would find it hard to say that ants have souls. I'm sure at least some fish have souls, but insects just seem too mindless and simple.
The word "animal" is similar to the word "soul" in that they can have different meanings depending on the context in which they are used.
In the OT the Hebrew word "nephesh", translated "soul", refers to creatures with "the breath of life", so it should be obvious that an OT animal in this context is different than how a biologist might define the English word "animal". Thus, it is not always reasonable to apply a biological definition to an English translation word, if one wants to reflect the meaning the original author wished to convey.
