Bathybius \Ba*thyb"i*us\, n. [NL., fr. Gr. baqy`s deep + bi`os
life] (Zool.)
A name given by Prof. Huxley to a gelatinous substance found
in mud dredged from the Atlantic and preserved in alcohol. He
supposed that it was free living protoplasm, covering a large
part of the ocean bed. It is now known that the substance is
of chemical, not of organic, origin.
