Researchers have seen the interesting burrowing and feeding behaviour of a deep-sea anemone (Iosactis vagabunda) at the at the Porcupine Abyssal Simple (PAP), just about 5,000 metres deep within the Northeast Atlantic Ocean.
“We used time-lapse images to look at 18 folks over a duration of roughly 20 months at 8-hour periods, and one particular person over 2 weeks at 20-minute periods,” the scientists say within the new learn about, printed in Deep Sea Analysis Phase I: Oceanographic Analysis Papers.
The time-lapse pictures allowed the researchers to achieve insights into the species’ burrowing behaviour – one thing that’s now not imaginable thru nonetheless images.
“In each and every burrow transfer, the animal disappears from view by means of taking flight into its burrow, then a small mound seems a brief distance from the unique burrow,” says the learn about. “This mound grows and is damaged alongside the crest earlier than the animal emerges from the apex of the mound, tentacles first, and establishes itself within the new burrow with its disk flush with the sediment floor and tentacles prolonged.”
In addition they noticed the anemone plucking natural debris from the water with its tentacles and bringing them to its mouth to consume.
