Leedsichthys

Leedsichthys is a massive "giant of the ocean" ranges from 13.5 to 27.6 meters in length and lived during the Mid Jurassic. It is a bony fish and its full name is Leedsichthys problematicus and could be killed by the long- living shark Hybodus. It is actually the biggest marine creature specified, but a strange creature was heard from the ocean depths, and was probably 200 meters long. It lived in Leeds, UK, an area where a pest named Liopleurodon lived. This creature's name means 'Leeds,' 'fish,' and was named in 1889.
