The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we evolve a new sex gene. The good news is two branches of rodents have already lost their Y chromosome and have lived to tell the tale. A 2022 paper in Proceedings of the National Academy of Science shows how the spiny rat has evolved a new male-determining gene.

Fast Fauna Facts #3 - Winged Argonaut (Argonauta hians)
Family: Argonaut Family (Argonautidae)
IUCN Conservation Status: Least Concern
Like the other small octopuses in the argonaut family many Winged Argonauts appear to have spiral-shaped external shells similar to those of nautiluses or ammonites, but this isn't quite the case - what appears to be an argonaut's shell is only seen in adult females, and is actually a thin-walled, calcium-based case secreted from and held by a specialised pair of arms in order to carry fertilized eggs until they hatch. Found in non-polar waters worldwide, Winged Argonauts are found mainly near the surface in the open ocean (in contrast to most octopuses, which are bottom-dwellers,) feeding on small floating invertebrates and often using their suction cups to cling to flotsam or larger animals (sometimes including other argonauts) for protection; when faced with a predator, they may attempt to position the animal they're riding on between them and the perceived threat to act as a meat shield.

Humans have been consuming alcohol for thousands of years, but we're not the only ones with a taste for it! The pen-tailed treeshrew's diet consists almost entirely of naturally fermented nectar, which can have an alcohol content as high as 3.8%. Given their small size, that's the human equivalent of consuming 10-12 glasses of wine. However, this species is able to fully metabolize the alcohol and avoid the intoxicating side-effects.

Even though they have a clam like shell, with 2 sections, they are in fact snails (class Gastropoda). They are marine snails, found throughout the Ino-Pacific. There are 6 species which are various shades of green. Julia are tiny, only reaching a length of up to 6 mm long. They feed on algae, and incorporate the chloroplasts from the algae into their bodies. Some of the chloroplasts remain photosynthetic, and the snails are able to feed on the products of this photosynthesis. This process is called kleptoplasty.
