Dang it. I knew i needed to check to make sure it isn't 5th declension. Anyways here is the declension, since someone had already asked about the ablative 'specie.'

Singular
N species
G speciei/specie (early)
D speciei
Ac speciem
Ab specie

Plural
N species
G specierum
D speciebus
Ac species
Ab speciebus

The nominative is used when a noun is the subject.
The genitive is used when a noun modifies another noun, i.e. posessive.
The dative is used with some prepositions and when the noun is the indirect object.
The accusitive is used with some prepositions and when the noun is a direct object.
The ablative is used with some prepositions.

The interesting think is that "species" is related to "specere" which means "to look at." "Appearance" is probably its most literal meaning in Latin. I guess that means that the morphological species concept is redundant.

What annoys me is people who think that there exists a species called Homo sapien. This includes the US Congress.
