This is a reconstruction of a Carcharodon Megalodon jaw that hangs on the wall at The Deep, Hull. The name Megalodon means “big tooth” in Ancient Greek. The C. Megalodon is regarded as one of the largest and most powerful predators in vertebrate history, fossil records suggest that the shark could reach up to 18m. There is some debate among scientists as to whether C. Megalodon is a close relation of the Great White or a separate genus.
These are Aurelia aurita – also called moon jellyfish, common jellyfish or saucer jellyfish. The species in the Aurelia genus are so closely related that is impossible to tell them apart without genetic sampling (lucky for me, the aquarium had a name plaque). Apparently one of the best ways to identify Aurelia is by their four horseshoe-shaped gonads. The jellyfish can be found showing off their lucky gonads along the eastern Atlantic coast of Northern Europe and the western Atlantic coast of North America in New England and Eastern Canada. In general they are an inshore genus that can be found in estuaries and harbours.
The Deep is a public aquarium and centre for marine research. The aquarium tanks total 2,500,000 litres of water and the centre has seven different species of shark.
