Otospermophilus

Otospermophilus is a genus of ground squirrels in the family Sciuridae, containing three species from Mexico and the United States. Otospermophilus was formerly placed in the large ground squirrel genus Spermophilus, as a subgenus or species group. Since DNA sequencing of the cytochrome b gene has shown Spermophilus to be paraphyletic to the prairie dogs and marmots,[1] it is now separated, along with six other genera.[2]

gollark: https://freedns.afraid.org/ may work instead?
gollark: Unfortunately, I don't think DuckDNS is usable for this täsk.
gollark: I can do helloboi.osmarks.net at least?
gollark: I don't think DuckDNS can in fact be used for this. Troubling!
gollark: I don't know if they can do CNAMEs somehow, but I can manually do updates from my end if you give me the token or something.
