I'll point out, however, that it's pretty standard English (and language change in general) to shift like this. The normal word species is both singular and plural (I've heard and seen specieses, and from biologists at that) but it ends in an -s that is clearly not possessive. It only makes sense that it would be reanalyzed by language learners as species being the plural form of specie. Species and specie are actually related too, so it's sensible really.

species (n.)
late 14c. as a classification in logic, from Latin species "a particular sort, kind, or type" (opposed to genus), originally "a sight, look, view, appearance," hence also "a spectacle; mental appearance, idea, notion; a look; a pretext; a resemblance; a show or display," typically in passive senses; in Late Latin, "a special case;" related to specere "to look at, to see, behold," from PIE *spek- (see scope (n.1)). From 1550s as "appearance, outward form;" 1560s as "distinct class (of something) based on common characteristics." Biological sense is from c. 1600. Endangered species first attested 1964.

specie (n.)
"coin, money in the form of coins, metallic money as a medium of exchange" (as opposed to paper money or bullion), 1670s, from phrase in specie "in the real or actual form" (1550s), from Latin in specie "in kind" (in Medieval Latin, "in coin"), from ablative of species "kind, form, sort" (see species).

It's kind of harsh to be annoyed with people for typical language change.

If anything...it gives proper English users a good chuckle. :)
