Ancient seagrass: ‘Oldest living thing on earth’ discovered in Mediterranean Sea

Australian scientists sequenced the DNA of samples of the giant seagrass, Posidonia oceanic, from 40 underwater meadows in an area spanning more than 2,000 miles, from Spain to Cyprus.
The analysis, published in the journal PLos ONE, found the seagrass was between 12,000 and 200,000 years old and was most likely to be at least 100,000 years old. This is far older than the current known oldest species, a Tasmanian plant that is believed to be 43,000 years old.
Prof Carlos Duarte, from the University of Western Australia, said the seagrass has been able to reach such old age because it can reproduce asexually and generate clones of itself. Organisms that can only reproduce sexually are inevitably lost at each generation, he added.

BLUE BELL TUNICATE COLONYClavelina moluccensis©Nick Hobgood
While they look like vacuum cleaner hoses, they are actually tunicates or sea squirts and not man-made trash. 
Bluebell tunicate, blue bell tunicate, or Blue Sea Squirt, is a species of tunicate (sea squirt), in the genus Clavelina (the “little bottles”). Like all ascidians, these sessile animals are filter feeders.
This species is 0.5-2.5 cm long, and light to medium blue in colour. The top of the zooids contain characteristic dark blue patches and spots that are always visible
This species is found in the waters around Australia, Western Pacific, Indonesia, Papua New Guinea, Mariana Islands, Philippines, Singapore, and Malaysia.
This species grows in clusters attached to dead coral or other hard substrates, normally under overhangs. 
Tunicate blood is particularly interesting. It contains high concentrations of the transition metal vanadium and vanadium-associated proteins as well as higher than usual levels of lithium.  Some tunicates can concentrate vanadium up to a level one million times  that of the surrounding seawater. Specialized cells can concentrate  heavy metals, which are then deposited in the tunic.
