Reason: I've noticed the isopod and decapod tags weren't using the English names, even though they had them (and isopod was even aliased to isopoda), and then dove deeper and found some things that don't feel like they should be happening. EDIT: Upon closer inspection, it seems to be due to the fact that the 'decapod' tag is already being used to describe characters with 10 pairs of limbs. I believe this should instead be done with the tag 10_legs, however.
Most noticeably hermit crabs are decapods, but not all of them are marine. This means decapods cannot imply marine. Some hermit crabs are terrestrial throughout their entire adult lives and only are aquatic in their larval stages, like the coconut crab.
On a side note, something I am not touching here but I think isn't the worst thing to consider - currently, 'true_crab' is aliased to 'crab', but I think having the brachyuran crabs tagged as 'true_crab' wouldn't go amiss. There have been posts in the forums about coconut crabs implying 'crab', which with how the tag is used cannot be done but the confusion is understandable.
Follow up once this goes through
