In the depths of the ocean, a new discovery has been made. A nursery full of deep-sea octopus. The new octopus species was discovered along seamounts in a 100-square-mile area off the Pacific coast of Costa Rica. The team of international scientists found two octopus nurseries connected by hydrothermal springs during their first expedition in June. In a different location away from the springs, they also observed several other new octopus species. The expeditions were led by Beth Orcutt of the Bigelow Laboratory for Ocean Sciences and Jorge Cortés-Núñez of the University of Costa Rica. "It seems that they're four new species of octopus in this area, which is not very large, which is amazing," says Cortés-Núñez. "It was unexpected to find so many species of octopus in a small area, first and second, at 3,000 metre depth. So, it's very deep." One of the new octopuses is a new species of Muusoctopus. It will be named Dorado Octopus, after the initial location of the discovery - a small outcrop of rock, unofficially called El Dorado Hill. Scientists say the new species of Muusoctopus adds to evidence they brood their eggs in warm springs on the seafloor. Over 160 deep-sea animal specimens have been collected from the December expedition. The specimens will be archived at the Museum of Zoology at the University of Costa Rica. A further 150 specimens were also collected in June. Scientists also discovered a deep-sea skate nursery at the top of another seamount in Costa Rican waters, nicknaming the site, Skate Park.
