Bipalium is a genus of large predatory land planarians. They are often loosely called “hammerhead worms” or “broadhead planarians” because of the distinctive shape of their head region.

Hammerhead worms have no respiratory system, no circulatory system, no skeleton, and a mouth for an anus. Predatory and large, with some species capable of growing to half a meter long, hammerhead worms are a global menace. Native to the tropic and temperate zones of Asia and Australasia, hammerhead worms have invaded almost every corner of Europe and the United States.

A number of hammerhead worm species feed exclusively on earthworms, literally tearing them apart before dissolving them in enzymes and drinking them up.
Destroying native populations of earthworms wreaks havoc on native ecosystems.

TIL a local fisherman in Costa Rica nursed a crocodile back to health after it had being shot in the head, and released the reptile back to its home. The next day, the man discovered “Pocho” had followed him home and was sleeping on the mans porch. For 20 years Pocho became part of the mans family

The northern hawk-owl (Surnia ulula) is a non-migratory owl that usually stays within its breeding range, though it sometimes irrupts southward. It is one of the few owls that is neither nocturnal nor crepuscular, being active only during the day. This is the only living species in the genus Surnia of the family Strigidae. The species is sometimes called simply the hawk owl; however, many species of owls in the genus Ninox are also called “hawk owls”.

The flammulated owl (Psiloscops flammeolus) is a small, nocturnal owl approximately 6 inches long with a 14 inch wingspan.

The owl gets the name flammulated from the flame-like markings on its face.

The flammulated owl is similar in appearance to the western screech owl, but is only about one-quarter the mass, lacks large ear tufts (but has small ear tufts that are barely visible), and has dark eyes and a different voice.

Unlike many owls, they are migratory, leaving Canada and the United States in the fall.

hognoses are fucking ridiculous

ok. i had to look this up, because this seems just too ridiculous. and wiki does not disappoint: “…
the hognose snake will often roll onto its back and play dead with its mouth open and tongue lolling, going as far as to emit a foul musk from the cloaca.
Emission of cloacal musk is considerably less likely than in many other
species. If the snake is rolled upright while in this state, it will
often roll over again as if to insist that it is really dead.”
