Spiders Also Live in Our Oceans

If it helps, sea spiders aren't technically true spiders. They are related to both spiders and crabs, and usually look similar with 8 legs, but they have some distinct differences.

Most sea spiders stay really small, only millimeters in size, but some can be much larger than any land spider. Sea spiders also breathe through their leg exoskeletons and since their bodies are so tiny, they also store most of their vital organs in their legs. Sea spiders eat their prey differently too. Instead of bitting, they will stab a soft bodied prey (like a sea anemone) with their proboscis tube, and suck up their insides like sipping through a straw.

So which do you like better, land spiders or sea spiders? 🕷️
