Vampire sea spiders suck on prey

For over 100 years, scientists have been puzzling over how exactly to classify sea spiders or pycnogonids. They are arthropods, but which type?

“They are very weird looking animals,” says Claudia Arango of the Australian Museum in Sydney… “They have a proboscis that’s like a straw that they insert into the animals and suck out the juices.”

Strangely enough, for me this doesn’t quite have the same squee factor as the piglet squid!
