The not-snakes that are very snakey because they are shaped like... snakes

Bizarre caecilians may be the only amphibians with venomous bites

Microscope and chemical analyses suggest that, like snakes, caecilians have glands near their teeth that secrete venom.

Caecilians are amphibians like salamanders and frogs, but they're often mistaken for snakes because of their long, legless bodies. Now, scientists think that the similarities between the two are more than skin deep.

New microscope and chemical analyses suggest that, like snakes, caecilians have glands near their teeth that secrete toxins. The discovery raises the possibility that caecilians may be the first amphibians found capable of delivering a venomous bite.
...
That these snakelike animals seem to possess a venomous bite even somewhat akin to snakes' isn't likely to be a coincidence, Antoniazzi says. "We think it has to do with this fact that they have similar bodies," she says. Without limbs to subdue prey, both caecilians and snakes benefit from having oral chemical weapons.

You just wait. Soon the earthworms will secrete venom, and then we will all be sorry! #Venom2020

I thought that manga had changed that to "Xexexexexexexexe" or "Huehuehuehuehuehuehuehue".

Though the not-snake appears less like a tentacle, and more like a chest-burster. Just don't confuse caecilians with Sicilians.

Some segmented worms are in fact pretty dangerous.

Absurd Creature of the Week: The 6-Foot Earthworm That Sounds Like a Draining Bathtub

Perhaps Australia's most remarkable creature is a gentle, extremely delicate colossus few have had the privilege of glimpsing: the giant Gippsland earthworm, which can grow to some 6 feet long. Give it a stretch--only if it’s already dead, you chucklehead--and it can easily double in length.

Bonus science: Earthworms can digest plant toxins:

Answer to earthworm's ability to digest poisons unearthed by scientists

All plants contain toxins which continue to work after leaf fall, so how worms are able to stomach dead grass and leaf litter has long been a mystery

Yes, and sometimes they dress up in a robotic spacesuit and carry a ray gun. It is known.

Never go in against a Caecilian when death is on the line.

convergent evolution is a thing. Look at all the completely unrelated things that evolve into crabs.

Got any non-arthropod examples?
