New Upside-Down Alien Species Discovered in Underwater Cave
Scientists exploring the Great Barrier Reef using a remote operated vehicle (ROV) have discovered three new species of carnivorous sponges, including one that resembles the parasitic "alien wanderer" from the book and movie "The Host." The sponges were found in an underwater cave and on rocks, and were identified based on their body shapes and physical structures. The use of ROVs in discovering several sponges shows the technology's "immense value to carefully observe and collect (sponges) from cryptic habitats," researchers said.
