What’s Supersizing Antarctica’s Sea Spiders?
Polar sea spiders grow bigger than their equatorial brethren.
by Meredith Swett Walker .December 29, 2015With eight spindly legs, a minimalist body, and long proboscis, sea spiders look like something from the fever dream of an arachnophobic science fiction author. But sea spiders are very real, and they live all over the world.

They’re not technically spiders. Most often, sea spiders are small, cryptic creatures.Yet in the Arctic Ocean and Southern Ocean, sea spiders grow huge. But they’re not the only ones that do.
