An international team of marine scientists has discovered 30 new species of invertebrates, including 10 bamboo corals, four octocorals, one brittle star and 11 sponges – as well as four new species of crustacean known as squat-lobsters, in deep water surrounding the Galapagos, the Ecuadoran archipelago’s national park authorities announced on Monday. Al Jazeera reports that the expedition explored, for the first time, three steep-sided underwater mountains, or seamounts, located near the islands of Darwin and Wolf in the archipelago’s north, home to the world’s largest shark population.
