Question

In 2019, the "scaly-foot" Chrysomallon squamiferum became the first species from one of these habitats to be added to the IUCN Red List. In 1996, the 60-meter-tall "Godzilla" structure at one of these habitats near Oregon collapsed. (0[1])One species that congregates in these habitats has hair-like extensions of their shells where colonies of chemosynthetic bacteria live, and is commonly described by the adjective (0[1])(*) "yeti." The Knorr discovered the first of these habitats in 1977 about 250 miles northeast of the Galápagos. (0[1])In 1979, researchers from Scripps found the first of these habitats powered by a Black Smoker while using ALVIN. For 10 points, name these deepwater habitats that can get as hot (10[1])as 700 degrees Fahrenheit. ■END■ (10[2])
