A reclusive mud-dwelling worm has been found alive for the first time, even though the fossils it leaves behind have hinted at its existence for more than 200 years.
About a dozen live specimens of the baseball bat-sized giant shipworm were finally discovered in the mud of a shallow Philippine lagoon after an extensive search.
Experts soon found that bacteria living in the gills of the creature produce enough food for the worm, which is encased inside a long tube made of the calcium carbonate it secretes. The gunmetal black bivalve also uses hydrogen sulphide in the water as an energy source.
The shells, in all likelihood, contributed to the myth of the Unicorn.
