First of all we would like to apologize for the rather unfortunate photos of this new and completely different living deep sea anemone and hope to be able to deliver better pictures soon.
The special behavior, i.e. the extraordinary locomotion and the active catch of especially large prey depth could be documented with the help of many time-lapse photographs, Iosactis vagabunda moves actively on and under the sandy bottom and catches bottom-dwelling worms, which are up to 15 x times as large as the anemone itself.
It took the anemone almost an entire day to swallow its meal.
The scientists noticed another unusual behavior of the anemone that may even put it in potential danger, while feeding, a process that took 24 hours in the case of the documented giant worm, the had moved into a vertical-standing position that could be an invitation to a protein-rich two-course meal (anemone and worm) for potential predators.
Iosactis vagabunda can burrow underground and reappear in a completely different location. And it doesn't happen that fast - time-lapse footage showed that it took an anemone more than 22 hours to enter a hole and reappear a few inches away.
This previously unique anemone would be discovered and documented at great depths in the Porcupine Abyssal Plain in international waters adjacent to the Irish Continental Margin.
