Did you ever hear about “Ambergris”? 😀
This picture underneath looks like a weird rock for you? Well…strictly speaking, this mysterious, waxy substance has relatively little to do with common rocks. It is “Ambergris” or grey Amber (Ambra grisea), with other words the vomit of Sperm Whales (Physeter macrocephalus). It is built in the intertestines of Sperm Whales and can be found floating in the ocean or is washed up to the shorelines. The exact cause of the formation of this substance has not yet been fully investigated.
Squid and Octopus are on the menu for Sperm Whales. As they have very sharp beaks, the Whales can not digest them. The Amber could function as a shield or a way to protect from the beaks of squids. The substance binds the beaks and helps getting rid of these problematic remains of their meals (see picture above, right).
When the Amber is still fresh, it has a marine, fecal, not so nice odor. Nevertheless, with age it develops a scent, which is said to be sweet and earthy and is highly valued in perfume industries. As the supply is very irregular and it is rarely found, high-quality ambergris can be sold for up to $20.000/ per kilogram (Golds price: $44.000/ per kilogram). So always keep your eyes open while taking a walk at the beach… maybe you will find a piece of the precious substance in front of the coast of São Miguel and get some extra money for your vacation on the Azores 😉
Maybe the digesting problem of the beaks has something to do with our recent discoveries of headless Seven-arm Octopusses (Haliphron atlanticus). If you want to have some more information on the topic, you can read about it in one of our previous blog posts here 😀
