Oh and by the way, I ordered swordfish ... which eats the escolar (snake mackerel) and the oilfish. So do the fish do the same thing in the sea and spray amber oil everywhere??

This is so true and made me laugh - I'm still recovering from a BAD attack, and the smell is unbelievable too! Like a heavy mineral oil or strange flower perfume. It does stain your clothes and sanitary towels can't catch it all - it goes everywhere!!! It soaked through a folded towel in a split second! It isn't an allergy or intolerance to a type of food, it is caused by residues in the fish (you'd need to study the food chain) - look up Keriorrhoea if you want to know more. I thought something dreadful was happening and I might never recover!!! So much for a great holiday in Madeira!
