Video of a Costa Rican Onycophera
Loading...
Uploaded by InfiniteWorld on Nov 7, 2007
We found this Onycophora (velvet worm) at the Las Cruces field station in Southern Costa Rica. Onycophora are cool, little understood, ancient critters that are related to the Arthropods (insects, crustaceans, etc).
Their body is entirely soft and they move pneumatically, that is, they don't really have muscles, just different sets of valves that inflate and deflate their legs with fluid so they can walk. That's why it looks so cool as it glides along.
Onycophera shoot a sticky substance out of their antennae, to capture prey.
Supposedly, the males mate with the females by just poking them in the side and squirting sperm into the hole. I think that is why the Onycophera in the video has the little white hole on its left side.

These creatures predate cockroaches or even insects (or anything else that has legs). It's thought that they were the first creatures that could "walk".

It is a living transitional form between segmented worms and arthropods. Take that creationists!

@ InfiniteWorld:
Do they give birth to living youngs or do they lay eggs?
You write in the text below the video:
"Onycophera shoot a sticky substance out of their antennae, to capture prey."
I don't think that`s correct. They spit this sticky substance out of special glands underneath their antennae, as far as I know.
