Forget about the front crawl; this strange creature is performing the front crab!
The rare and mysterious orangutan crab was observed swimming just off the Indonesian island of Lembeh.
The tiny creature looks unusual as it kicks off from the seafloor and flails its legs to propel itself through the water.
Atsushi Sadaki, 59, a business design consultant who has been scuba diving for 20 years, captured the footage.
“It’s an orangutan crab, which is uncommon.”
“I’ve seen a few, but this is the first time I’ve seen one swimming.
When I was diving at night, I discovered it.
“I have to say I found it very funny. It made me laugh.”
