Of the eight species of marine turtles worldwide, five are reported to be found in the Philippines: the Green Turtle, Hawkbill, Leatherback, Olive Ridley, and Loggerhead.
The world's largest pearl was discovered by a Filipino diver in a giant Tridacna (mollusk) under the Palawan Sea in 1934. Known as the "Pearl of Lao-Tzu", the gem weighs 14 pounds and measures 9 1/2 inches long and 5 1/2 inches in diameter. As of May 1984, it was valued at US$42 million. It is believed to be 600 years old.
