Frilled Shark

A pair of Frilled Sharks in-game.

The Frilled Shark is a 6 Star Marine animal that must be cloned back by using Gene resources on certain maps. It is available in Wildlife Zoo Deluxe (The US release of WP2 and Marine World); However, it is unknown if it is also in the original Marine World expansion pack. The Frilled Shark is easy to keep and only needs to eat fish and swim, but can take forever to breed. When purchasing it as an adult due to a glitch, it costs $500,000.
