Some of Titanic's fauna has never been seen anywhere else; James Cameron's 2001 expedition discovered a previously unknown type of sea cucumber, lavender with a glowing row of phosphorescent "portholes" along its side.[106] A newly discovered species of rust-eating bacterium found on the ship has been named Halomonas titanicae, which has been found to cause rapid decay of the wreck. Henrietta Mann, who discovered the bacteria, has estimated that the Titanic will completely collapse possibly as soon as 2030.[107] The Canadian geophysicist Steve Blasco has commented that the wreck "has become an oasis, a thriving ecosystem sitting in a vast desert".[85] In mid-2016, the facilities of the Institut Laue-Langevin used neutron imaging to demonstrate that a molecule called ectoine is used by Halomonas titanicae to regulate fluid balance and cell volume to survive at such pressures and salinities.[108]
