Exobiology Classification

[roguebfl]

I Want to to come up with a way to classify exobiology especial, such that calling a xenobiology created a 'Parrot' or a 'Bear' isn't nonsense in the setting.

I was thinking of taking the existing scientific names for earth's creatures and pretending 'terra' to the name, than each world would get it's own root, but bellow the root if they share the characteristics of an eathar chrater they get same subname.

The system would problem need some notation for created than been genetically modified to either be adapt to a world, or used to terraform a world
