A pathologist from the University of Las Palmas in the Spanish Canary Islands found ambergris (also known as whale vomit or 'floating gold') worth €500,000 (around ₹4.5 crore) inside the colon of a beached sperm whale. "What I took out was a stone about 50-60 cm in diameter and weighing 9.5 kg," said Antonio Fernandez Rodriguez.
