We recently went on a wonderful dive trip in Cenderawasih Bay. Which is in Western Papua, Indonesia.
This was filmed at the Fisheries jetty at Biak. Biak is an island in the North at the “entrance” to Cenderawasih Bay, which in it’s turn lies on the Eastern side of West Papua.
The worm is about 500cm long and the Goby about 3 cm long. Really a David and Goliath situation.
The Worm must have been scavenging in the Goby nest. The Goby moved extremely fast. Even in slow motion, it’s still too fast to see.
The worm seems to be of the Syllis sp.in the Syllidae family.
The Goby looks like a Shrimpgoby, but it is very difficult to identify it accurately. But, it is extremely fast. It would be interesting to know what happened in the following hours to the 2 creatures.
