Proposal:

remove alias crotaphytidae -> collared_lizard
remove alias crotaphytid -> collared_lizard
remove implication leopard_lizard -> collared_lizard
create alias gambelia -> leopard_lizard
create alias crotaphytidae -> crotaphytid
create implication collared_lizard -> crotaphytid
create implication leopard_lizard -> crotaphytid

Justification:
The Crotaphytid family isn't very popular within the furry fandom right now, but e621's current tag implication/alias structure will lead to improper tagging if these species should grow in popularity in the future.

The reptilian family Crotaphytidae consists of two genuses:
Gambelia (leopard lizards)
Crotaphytus (collared lizards)

Currently, leopard_lizard implicates collared_lizard, which is incorrect. Collared lizards are a distinct genus from leopard lizards.

Furthermore, the family name Crotaphytidae and related descriptor, Crotaphytid, currently alias to collared_lizard. This is also incorrect, as Crotaphytidae includes the leopard lizards, which are not collared lizards.

The proposed BUR will avoid potential errors such as a long-nosed leopard lizard being incorrectly tagged as a collared lizard.

The bulk update request #3306 (forum #345122) has been rejected by @monroethelizard.

Please vote on this message. The content is the same as the original post in this thread, just I've had to split the script in two due to existing aliases.

The bulk update request #3307 is pending approval.

remove alias crotaphytidae (0) -> collared_lizard (251)
remove alias crotaphytid (0) -> collared_lizard (251)
remove implication leopard_lizard (0) -> collared_lizard (251)
create alias gambelia (0) -> leopard_lizard (0)

Final note:
In addition to the four commands in my proposed script above, I would like to propose these three additional alias/implication changes, to implicate the broader crotaphytid classification for all collared lizards and leopard lizards. However, if I understand correctly, I think the unalias and unimplicate commands related to crotaphytidae and crotaphytid have to go through first. When I tried to submit everything in one BUR, I got an error which I think is caused by the existing alias of crotaphytid to collared_lizard.

alias crotaphytidae -> crotaphytid
implicate collared_lizard -> crotaphytid
implicate leopard_lizard -> crotaphytid
