Ever eat one of these? Try not to puke while chewing on it.

[Speed Demon]

This bizarre creature lives off the coasts of south-eastern Australia and Tasmania, at depths of between 1000 and 4000 feet, where atmospheric pressure is several dozen times higher than at sea level.

Its gelatinous body is just slightly more dense than water, and it spends its life "bobbing around" in the depths.

It feeds on crabs and lobsters and will eat you too, if given a chance.
