Did the enormous West Antarctic Ice Sheet collapse the last time global temperatures were 1.5°C above preindustrial levels? The answer lay in the DNA of an octopus.
Thousands of pearl octopuses were discovered in 2018 lining thermal vents near a deep-sea volcano. Researchers now know why octopus moms gather there.
