The culprit follows extruded sand dunes like the seabed
A worm in the Red Sea bottom is the author of the long-winding, snake-like sand dunes in the video that cause a social network fever.
Sand dunes created by oak worms.
Diver Vital Bazarov spotted the zigzag- like sand dunes underneath while swimming in the Red Sea off Egypt in late September, according to IFL Science. In the video recorded by Bazarov, the special worm creates large rolls of sand on the seabed.
Attracted by the sight, the experienced diver swims closer and watches the oak worms (acorn worms) dig deep burrows that excrete the sand they have eaten before. Oak worms smoke seeds, filter and eat plant and animal debris, and then emit filtered sand into characteristic debris. "I have seen these settlements many times but have never witnessed the process of them being created," Bazarov said.
With debris eating properties under the ocean, oak worms are like a small plant that consumes organic matter. Oak worms are marine creatures that feed on sediments and debris in the ocean floor.
