Scotland's famous Loch Ness monster could possibly be a large eel, scientists announced last week. The scientists made the announcement after they completed a study of genetic material from the Loch's cold waters. The scientists said their DNA results ruled out the presence of large animals such as dinosaurs. But there was a lot of eel DNA in the water, said Neil Gemmell, a geneticist from the University of Otago in New Zealand. Eels are long, bony fish that look like snakes. They are usually thin and have soft skin. The international team of scientists collected water samples of what they are calling environmental DNA, or eDNA. Scientists have also used eDNA sampling as a tool to study sea life like whales and sharks. The Reuters news agency describes how eDNA works: Whenever a creature moves through its environment, it leaves behind very small amounts of DNA from skin, scales, hair and waste. Scientists can capture the DNA, then try to identify the order of the genetic information. They can identify an animal by comparing the captured DNA to large computer databases. The most famous picture of the Loch Ness monster was taken in 1934. It shows a head on a long neck coming out of the water. There have been many unsuccessful attempts to find the Loch Ness monster. In 2003, the British Broadcasting Corporation paid for scientific research that used sonar beams and satellites to study the full length of the loch. The most recent attempt was three years ago. An unmanned vehicle found a creature, but not the one it was looking for. The discovery was, in fact, a model used in the 1970 film "The Private Life of Sherlock Holmes." It sank nearly 50 years ago.
