Sea Creature or Entrails?

From DSN, it’s everybody’s game of science, trivia, and fun! Contestants are you ready to play…



I’m your host Dr. M and let me introduce our first video trivia question brought to you by Neatorama. In the video below we witness a container full of water with a pulsing series of tubes!  Our team of DSN crack experts found this information associated with the video

Found on April the 19th, 2011 @Kiel, Germany during works at the docks by empoyees of the port. The thing was captured and then brought to the IFM-Geomar-Institute, it is unclear what it is. Suggestions are welcome.

Contestants are you ready to answer? Is it wormy sea creature from the great depths or just entrails?

The answer is……..entrails. What you see in the video is actually freshly removed intestine, likely from a pig, the webbing in between is actually the mesentery, a double layer of membrane that contains blood vessels, lymph vessels, and nerves and connects the two parts of the small intestine. It is not a pulsing sea creature from the deep.


Congratulations to all those contestants who answered correctly in this episode of everyone’s favorite game!

He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.

  1. It’s obviously entrails, but why is it pulsing? It looks like there’s something in there with it, maybe a fish or something, but it’s really hard to tell.

    1. It’s the peristalsis of the intestines. It must be really, really fresh….
