Bat Tick (Carios kelleyi)

…a species of soft tick that is distributed throughout parts of North America, mainly Canada and the United States although it has also been found in Costa Rica. Like other soft ticks this species is a parasite of bats, as suggested by its name. Although they are also known to parasitize other animals including humans. Unlike other members of Argasidae C.kelleyi larvae are slow-feeding and take weeks to engorge.

Ticks are literally the worst animals

That is a terrible lie and YOU KNOW IT IN YOUR HEART

Some other bat ticks only feed on bat guano as adults, but their babies still need blood, and to stay safe, only feed intermittently.

Every day their mother carries them all up the wall of the cave, waits while they feed on a sleeping bat, then carries them all back down.

These are fins from a 500lb Bluefin Tuna

Tuna are members of the Scrombrid family, a group of fast swimming, partially warm-blooded apex predators, with highly streamlined bodies and retractable fins. 

In the image above, the large dorsal fin, with its rigid bony rays, can disappear completely into a deep groove on the body.This gives the fish its distinctive bullet shape, as it charges forward in the water. The fin is pulled out when the fish is slowing down, or turning to keep its cylindrical body from rolling over.

The distinctive little fins, or finlets in the last image are only found in this group of fish. Muscles beneath the skin allows them to move independently. There’s a few people out there researching this, but at the current time their exact function is unknown.

Side note: These don’t have motors. They’re completely momentum/wind-powered and literally just wander around beaches unsupervised like giant abstract monsters.

these are both amazing and COMPLETELY TERRIFYING

i’m unreasonably freaked out and disturbed by these

Is this in some kind of uncanny valley?? It’s like an uncanny Communist march or something.

And for some reason I can’t help but imagine these things eternally striding across a barren, lifeless world.
