So, we have a lot of maladaptive species that are poorly adapted for Polar regions, such as unexplained ectotherms. As such, I am giving them until the end of Week 26 to be improved or moved out of the polar regions. Any species left will be wiped out.

Here is the current list of maladaptive species that are on the chopping block:

Tileback
Rolling Flune
Tonboswarmer
Tilepillar
Pewpa
Drake Uktank
Flippskima
Morphous Swampbean
Elahpekomlap Bubblehorn
Bipedal Uktank
Chromanke
Crystank Shell
Crystank Flasprout
Crystank Walker
Luroot
Spitting Lizalagarto
Shortfaced Thornback
Voracious Anklebiter Thornback
Thumbwalker
Billdeka
Duramboar
Cryorasher
Bubble-Throated Anklebiter
Farmphibian
Shellear
Gushlych
Karybdos
Gliding Gushstrider
Spinebacked Probeface
Mountain Pedesorm



As well as the full list announced, there are some species that need elaboration on whether they are at risk of dying to the polar purge:

Bloody Nose Cotingo (elaboration)
Ringtailed Ketter (elaboration)
Squat Limbless (elaboration)
Violet Cadovermi (elaboration)
Wind Shrubite (maybe)
Snowsculptor Janit (elaboration)
Drakescooter (elaboration)
Festive Uktank (Basking?)
Sum-Humgrove (elaboration)
Lurcup (elaboration)
Seaplane Tonboswarmer (elaboration)
Cochliabite (elaboration)

To reiterate, these species have until the end of the Generation 165 to be replaced or have a descendant move out, otherwise they will be lost

Flippskimas' ancestor is mentioned to have antifreeze proteins, and there's no mention it lost them. One could argue that's not enough, but, in that case, its ancestor, the Scaled Diveskunik, should also be listed.

Yes, I agree, antifreeze proteins are sufficient for polar life @MNIDJM

The bodies of adult Bubble-Throated Anklebiter rot, producing heat like a compost heap. The pools they breed in are covered in ice, which would insulate them somewhat. (Unless "no more than five cm deep" would plausibly covered entirely by ice...) It's also mentioned that "While ectotherms, they warm up quickly due to their dark bodies and are well-insulated by a layer of fat." Is this only sufficient for cold-temperate, not mild-tundra?

I'm also not sure about the Bubble-Throated Anklebiter and for that matter the Farmphibian. The Farmphibian spends almost all its time in a warm microclimate.
