Researchers found Muusoctopus nursery grounds on a low-temperature hydrothermal vent off the shore of Costa Rica. The octopuses hang on to the rocks in inverted positions in order to protect their eggs.

Octopus nursery discovered in Costa Rica

The team, aboard the Schmidt Ocean Institute's research vessel Falkor, located the nursery nearly 2,800 meters below the ocean's surface. The expedition's footage, captured by the underwater robot ROV SuBastian, showcased breathtaking marine life, including octopus hatchlings, tripod fish, and vibrant coral gardens.
