Living sharks for shark feeders.

[Paleoguy]

A similar idea as goat feeders, but bigger prey items for some of the aquatics and more diversity for the lagoon enclosures. Sharks could be prehistoric or generic looking. My preference would be ancient sharks. Scientists would have to go through the same process as bringing back the dinosaurs, aquatic, and flying reptiles. During the dig for particular aquatic reptiles, shark fossils could be found among them. Those fossils could be used to make a viable genome of an ancient shark, or another type of aquatic life. That aquatic life would make the basis to create a more accurate food source for the aquatic reptiles and would create a more accurate environment increasing the creature's comfort. The more options of marine life there are for the aquatic reptiles, the greater the ratings for the creatures in their enclosures.
