This incredibly rare footage shows a burrowing sea cucumber using its long tentacles to consume microscopic plankton.
The hungry sea cucumber seems to be reaching out to grab the plankton before cramming it into its mouth.
Diving instructor Carlos Summers, 36, took this video of the greedy sea cucumber as he dived in the Philippines, off the southwestern coats of the Cebu Island.
While sea cucumbers are common, Carlos reckons that seeing them feed like this is very unusual.
The ex-paratrooper said: “I was astonished when I first saw it – I was within a few minutes of my no decompression limit, at which time I have to begin to ascend for safety, so I wanted to get as much footage as possible.
“I had a lot of difficulty identifying this creature. I see sea cucumbers often and they are photogenic and easy to identify but this was the first I had ever seen burrowed and feeding in this manner.
“I have not seen this again since and I was surprised to learn that that it was a sea cucumber. They really are common and all the divers I know are used to seeing them on just about every dive but none of them had ever seen this.
“This is my passion. Diving is my therapy after having served in combat in Afghanistan and Iraq. It is a lifestyle and it is absolutely essential to my health, sanity and wellbeing.
“I am also committed to conservation and to showing people the amazing bounty of our planet before we’ve exploited it too much. I fear that if I have children, one day they will only be able to see this beauty in photos.”
