Forget front crawl – this weird creature is doing the front crab!
The rare and mysterious orangutan crab was filmed swimming just of the Indonesian island of Lembeh.
The small creature makes for a strange sight as it kicks off from the sea bed and waves its legs to propel it through the water.
The video was shot by Atsushi Sadaki, 59, a business design consultant who has been diving for 20 years.
He said: “It is an orangutan crab and they are rare.
“I have seen one or two before but this is the first time I have seen one swimming.
“I was diving at night when I saw it.
“I have to say I found it very funny. It made me laugh.”
