Halomonas titanicae is a species of bacteria which was found on rusticles in the wreck of the RMS Titanic. It was discovered in 2010 when rusticle samples taken from the Titanic were analysed, and this bacteria, as it makes work of the Titanic's iron, has been known to cause rapid deterioration. Dr Henrietta Mann, the discoverer of the new bacterium, stated that in 1995, she assumed Titanic would last for 30 more years, but since Halomonas titanicae is consuming Titanic's steel at a much faster rate, it may be 15 to 20 years before the Titanic becomes a pile of rust on the ocean bottom.
