Blobfish, Psychrolutes (aka Mr Blobby)

A 285 mm SL Blobfish (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).

Notes

About the fish

The scientists and crew on board the RV Tangaroa affectionately called this fish 'Mr Blobby'. The fish's body is flabby and not adapted to be out of water!  The yellowish 'blob' on the right side of Mr Blobby's mouth is a parasitic copepod. The specimen now resides in the Australian Museum Ichthyology Collection (AMS I.42771-001). It was initially fixed in formaldehyde and is now preserved in 70% ethyl alcohol. The fixation process has 'tightened' Mr Blobby's skin so his 'nose' has shrunk and he no longer retains his 'cute' look.

Mr Blobby is psychrolutid fish (family Psychrolutidae).  Fishes in this family are called the blobfishes or fathead sculpins.  They are found in marine waters of the Atlantic, Indian and Pacific Oceans at depths between 100 m and 2800 m.  The common name 'fathead sculpin' refers to the large, globular head and 'floppy' skin that is typical of these fishes.  Little is known of their biology.  Some have been found with gastropods in the stomach.

About the larvae

Jeff Leis wrote “Little is known about the larvae of the family Psychrolutidae. Neither the eggs nor the larvae of the blobfish have been described, but other (Northern Hemisphere) members of the family have demersal eggs (= attached to the bottom), and the larvae are deep-bodied with short guts, a short blunt snout, and variable pigment. This information comes from Kendall (2011). Probably the best readily available source on the larvae of psychrolutids is the Ichthyoplankton Information System. However, this website is only about fish eggs and larvae from the NE Pacific."

About climate change

Jeff Leis also stated “Psychrolutids are cold-water fishes, found either at high latitudes, or in deep water. As such, I would expect that they would be adversely affected by the increasing ocean temperatures brought about by climate change. But, I am not aware of any studies that address this issue in psychrolutids.”

Mr Blobby is again famous. Check out the new Museum post for background about his interview on the Center for Future of Museums blog.

If you think Mr Blobby is beautiful, you should check out some of his neighbours in the deepsea fishes gallery

Hi Lynda and Michael.  Yes, it was great to see Mr Blobby adding to his fame on the Gruen Transfer last night.  Mind you, he is not from Tasmania or endangered, but that would have stood in the way of a fun story.  Either way I enjoyed watching 'The Pitch'.

Hi Mark, Hi Telio, Mr Blobby got a mention (and a picture) on the Gruen Transfer this evening - love to see his fame spreading into the world of advertising/comedy!

Hi Teilo, Thank you for your comment. You are not alone. I think the whole world loves Mr Blobby! I have added a few more details about the family to the page.
