This is a Yellow-Spotted Flatworm (Thysanozoon nigropapillosum). It is a species of polyclad flatworms belonging to the family Pseudocerotidae. We spotted this lovely creature while diving off the coast of Fiji.
Our dive guide referred to this enchanting invertebrate as a Yellow-Spotted Flatworm. However, it is also referred to as Gold-Speckled Flatworm, Yellow Papillae Flatworm, Yellow-Spotted Polyclad Flatworm and a few other names. A few years ago, I was diving in the Red Sea and the dive guides there referred to it as a Gold-Speckled Flatworm.
The day I filmed this clip, visibility was not that great underwater. There was a tropical storm heading towards the island. The storm was pushing sediment into the bay, which slightly reduced visibility. Thankfully, the storm changed direction and went back out to sea.
Thanks for visiting today!
What a pretty little creature with it’s delicate frill and polka dots!
