RE: Nah Nah I'm Not Dying Now... Immune Systems Are Natural Killers!

So something interesting relative to

Every animal has an Innate Immune System but only the vertebrate animals have the Acquired kind.

But reading from here (2007) and here (2014) actually look at evidence of invertebrates holding some degree of immune memory (i.e. an acquired immunity).

_{I am not saying you are wrong, its just something interesting on the subject.}
