The 27 Best Deep-Sea Species: #26 Pig Butt Worm

Pig Butt Worm, Chaetopterus pugaporcinus

This species bring a whole new meaning to butt face. It’s Latin name even means butt face.  I jest… it actually means resembling a pig’s rump. Chaetopterus is a polychaete and like other worms it has segments.  Some of the segments are just a little bit inflated.  But it’s not just it’s looks that puts this little fellow on our list.  It feeds by deploying a mucus cloud that traps material in the water.  Shaped like a butt and uses a mucus cloud to feed…enough said.

He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards.

  1. Ah, such diversity in naming conventions. Makes me wistful for my days doing real science . . . . . but why a pig butt? Could DSN have this creature as the first installment of a “Really creative sea creature renaming contest?”

  2. This has to be the coolest creature on the face of the earth! The Pig Butt Worm! Awesome! Love it! And here I thought the Sea Cucumber was funky lookin. *lmao*

  3. An inelegant name…perhaps popular culture is “dumbing down” a generation of biologists.

  4. Ha! Taxonomists have giving “inelegant” names to organisms since classification was founded. Linneaus himself would name the most ugly animals after people he disliked. I recommend taking a perusal through the Curiosities of Biological Nomenclature. Dumbing down and having sense of humor are entirely different magisteria here.

  5. woowwwww. i wonder waht kind of names they will have for other sae creatures in the future. pig butt worm?? they really went deep this time.. lol
