'Whale vomit' windfall could net Thai fisherman up to $1.2 million

Substance made by sperm whales is known as ambergris and can be sold for up to $40,000 a kilogram

A hard-up fisherman in Thailand is in line for a windfall of more than $1 million after finding a rare piece of expensive “whale vomit” on a beach.

Narong Phetcharaj was returning to shore when he saw a strange object in the surf at Niyom beach in southern Thailand’s Surat Thani province.

He found a large lump of a waxy mass called ambergris, which is French for grey amber.

The substance, which is regurgitated by sperm whales, can be sold for up to $40,000 a kilogram.

Mr Phetcharaj found a piece weighing about 30kg, which could be worth up to $1.2 million

The fisherman took the mass to experts at the Prince of Songkla University, who identified it as ambergris.

The substance is produced by sperm whales, which eat large quantities of cephalopods such as squid and cuttlefish and usually vomit out indigestible elements such as the beaks and pens.

Sometimes, these parts move into the whale's intestines and bind together, slowly becoming a solid mass which grows inside the huge mammal over many years.

The whale then vomits out the mass, which solidifies and floats on the surface of the ocean. It has a foul smell at first but after drying out, it develops a sweet and long-lasting fragrance, making it a sought-after ingredient in the perfume industry.

"None of the villagers has ever seen or touched a real whale ambergris before and that’s why everybody was happy," Mr Phetcharaj said.

"I'm so excited; I don’t know what to do. I plan to sell the ambergris as I’ve already received a certificate to prove that it's real.

"If I can get a good price, I'll retire from working as a fisherman and throw a party for my friends."

'I was out snorkelling when one of my colleagues told me there was a turtle under a ledge in a school of glass fish, about 10 metres down,' says Jan. 'When I dived down to look, the fish separated around the turtle perfectly. I said to her: ‘I think I just took the best photo I have ever taken’.'

Second place in Ocean Photographer of the Year, Henley Spiers: 'Diving amidst the barrage of gannets, I witness the violent synchronicity of these impressive seabirds as they embark on fishing dives,' says Spiers of this photo taken in the UK's Isle of Noss. 'They hit the water at 60 miles per hour (96kmh), an impact they can only withstand thanks to specially evolved air sacs in the head and chest. The bird’s agility transfers from air to sea where it also swims with incredible speed.'

Third place in Ocean Photographer of the Year, Matty Smith: 'A hawksbill turtle hatchling just 3.5cm long and a few minutes old takes its first swim,' says Smith of his photo taken in Lissenung Island, Papua New Guinea. 'It had emerged from an egg just minutes earlier with approximately 100 of its siblings. They quickly made their way into the ocean to disperse as rapidly as they could and avoid predation from birds and fish. I had to work quickly for this shot.'

The mystery of ambergris

The substance has been called the treasure of the sea and referred to as floating gold.

Its origin remained a mystery for years, with theories suggested it was hardened sea foam or the droppings of large birds.

However, it was not until large-scale whaling began in the 1800s that the discovered was made that the sperm whale was the material’s only producer.

Conflicting opinions still exist as to how ambergris emerges from the whale. Many believe that the whale regurgitates the mass – which is where the substance gets its nickname “whale vomit”. Some believe the whale pass the mass along with faecal matter, whereas others say the obstruction grows so large it eventually fatally ruptures the animal.
