A diving guide has formed special bond with a colossal Sperm whale which allows him to swim alongside him.
Swimming with a Sperm whale - A dive guide, Mr Armour is able to invite other snorkelers and divers along to share the experience of swimming with Scar the male Sperm whale.
Spectacular images taken last weekend near the Caribbean island Dominica show just how close Andrew Armour, a diving guide, is able to get to Scar, a 10-year-old male.
In one picture a large group of 'socialising' whales come together while in another they arrive in a perfectly formed procession.
The images show how over the course of a decade, Scar became comfortable enough with Mr Armour to allow him to stroke and gracefully swim alongside the 32-foot mammal.
Mr Armour, 45, from Dominica, said: "Our bond began in 2000 when my wife Rhona found him injured out at sea when he was just a calf. We think he might have been attacked by pilot whales but we are not sure.
"His head and dorsal fin were injured and he came to our boat, perhaps seeking some comfort. The most we could do was pet him and his injuries left him with some scarring.
"From then on he and another young female would approach us whenever they saw our boat. We could even call him over.
"Now he recognises me when I am swimming. I feel like he even knows my voice. I can get very close with him because we trust each other. I even clean lice off him and he lets me do it.
"Other whales in the area don't tend to stay in the same place when humans are around but Scar seeks interaction and seems to enjoy being petted."
Mr Armour is now able to invite other snorkelers and divers along to share the experience of swimming with Scar.
Last week he took underwater photographers Eric Cheng, 34, from San Francisco, California, and Tony Wu, 42, from Tokyo, Japan, to witness his amazing encounters with Scar and other sperm whales in his pod.
"When Tony and I first encountered Scar we had to continuously move out of the way to prevent the large whale from rubbing up against us," said Mr Cheng.
"Soon enough, we overcame the worry that is natural when confronting one of the world's largest carnivores in its native environment.
"We stroked and scratched Scar, who twitched and rolled over repeatedly in what appeared to be enjoyment.
"It's dangerous to anthropomorphise animals - even intelligent ones - but it was absolutely clear in this case that Scar wanted the interaction."
Dominica is a small, volcanic island in the southern Caribbean and is less than two hours by plane from San Juan, Puerto Rico.
Sperm whales live in the waters around the island all year round.
