A globster or blob is an unidentified organic mass that washes up on the shoreline of an ocean or other body of water. A globster is distinguished from a normal beached carcass by being hard to identify, at least by initial untrained observers, and by creating controversy as to its identity.
The term "globster" was coined by Ivan T. Sanderson in 1962 to describe the Tasmanian carcass of 1960, which was said to have "no visible eyes, no defined head, and no apparent bone structure." Other sources simply use the term "blob".
Many globsters have initially been described as gigantic octopuses, though they later turned out to be decayed carcasses of whales or large sharks. As with the "Chilean Blob" of 2003, many are masses of whale blubber released from decaying whale corpses. Others initially thought to be dead plesiosaurs later turned out to be the decayed carcasses of basking sharks. Others remain unexplained. Giant and colossal squid may also explain some globsters, particularly those tentatively identified as monster octopuses.
Some globsters were examined only after they had decomposed too much and seemed to represent evidence of a new species, or were destroyed—as happened with the "Cadborosaurus willsi" carcass, found in 1937. However, Canadian scientists did analyse the DNA of the Newfoundland Blob—which revealed that the tissue was from a sperm whale. In their resulting paper, the authors point out a number of superficial similarities between the Newfoundland Blob and other globsters, concluding a similar origin for those globsters is likely. Analyses of other globsters have yielded similar results.
