TIL about Eurypterids, or "sea scorpions", the largest known arthropods ever to have lived. The largest, Jaekelopterus, reached 2.5 meters (8.2 ft) in length. Many forms lived in brackish or fresh water, and their dual respiratory system allowed for short periods of time on land.

Am 8 foot long scorpion sounds positively terrifying.
Seems like there were so many good reasons to stay outta the water way back then.
