Not really a joke exactly...

...but still funny. This is an actual animal. The scientists who caught it nicknamed it Mr. Blobby. I like his nose thing.

A Fathead (genus Psychrolutes) trawled during the NORFANZ expedition at a depth between 1013 m and 1340 m, on the Norfolk Ridge, north-west of New Zealand, June 2003 (AMS I.42771-001). Photo: K. Parkinson © Australian Museum. The scientists and crew on board the RV Tangaroa affectionately called this fish 'Mr Blobby'. Note the parasitic copepod on Mr Blobby's mouth.
