Boggling bioturbators, Batman. It’s a wild herd of holothurians. Run for yur lives! Elasipodid holothurians are a dominant component of the mobile invertebrate megafauna on the Porcupine Abyssal Plain, northeast Atlantic. They occur in high densities over large areas (Smith et al. 1997).
Yes, but, where are they going? They’re up to something, for sure, never found milling around.
The images above and left are lifted from the awesome Abyssal image galleries at Bogleech.com, a website by Jonathan Wojcik about insects, parasites, monsters and peculiar things of every sort. Go there to learn more. For holothurians in action (ie spilling their guts), stop by the Echinoblog.
