Frilled Sharks have existed for around 280 million years, making them one of the oldest surviving species of fish on the planet. They are found in all major oceans, but are most commonly found in deep water areas near the coast. This ancient species has a long and interesting history, and is known by many different names including “living fossil”, “sea serpent”, and “dragonfish”. They get their name from their unique frill-like fin that runs along the back of their body. This fin is used to stabilize themselves while swimming and also acts as a sort of camouflage, making them blend in with their surroundings.
