The Southern Ocean giant sea spider is one of the most common sea spiders in the waters around Antarctica. It also lives in coastal waters off South America, South Africa and Madagascar, down to a depth of 4.9 kilometres. It is so widespread that some have wondered whether it really is a single species.
Where are Pycnogonida found?
Pycnogonids can be found from the intertidal regions to depths of around 7000 m. Most are small, but a few deep-sea forms reach up to 70 cm diameter across the legs. They feed by sucking juices from soft-bodied invertebrates through a long proboscis.
How do sea spiders survive?
As the spiders grow bigger, their skin gets holier, allowing them to fuel their larger bodies by absorbing the abundant oxygen packed into cold waters. It turns out this helps them get oxygen during hot workout sessions, too, suggesting they may find a way to survive as their habitats heat up.
