Liopleurodon (SciiFii)

Liopleurodon hesperos (name meaning "western smooth-sided teeth") is a species of marine reptile belonging to the Pliosauroidea, a clade of short-necked plesiosaurs, that originally lived in the European seas during the Callovian stage of the Middle Jurassic Period (c. 164 to 155 mya) as an extinct species, Liopleurodon ferox, and the genus itself was once extinct, but has since been brought back from extinction by SciiFii. Liopleurodon hesperos was originally planned to be included in Cretaceous Park located in Sacramento, California, but the shipping containments that had Liopleurodon hesperos was accidentally toppled over by another boat that rammed the boat, puncturing the transport tanks containing 13 Liopleurodon hesperos, which fell into the sea off the coasts of California. Ever since that event, the population of Liopleurodon hesperos had greatly increased from just 13 to more than 1,500 Liopleurodon hesperos living in the coastal and deep seas off the Californian, Oregon, Washington, British Columbia, and Pacific Mexican coastlines. Liopleurodon hesperos is a large animal, growing on average to be up to 6.4 metres (21 feet) in length, about that size of a killer whale (Orcinus orca) and the extinct Liopleurodon ferox. As a an apex predator, Liopleurodon hesperos primarily preys on other marine reptiles, squid, crustaceans, trilobites, sea scorpions, and fish, although it can occasionally feed on unwary seabirds and small sea-going pterosaurs, and it can also scavenge on carrion of various marine animals. Despite its size and fearsome-looking appearance, Liopleurodon hesperos does not prey on marine nor terrestrial mammals, and is a very active, playful animal in a manner similar to large dolphins such as killer whales, although is less intelligent due to its less brain power. Liopleurodon hesperos is generally solitary and prefers to live alone throughout its life except during the breeding seasons. The gestation period of Liopleurodon hesperos lasts around nine months and gives birth to either single or two babies at a time, which are cared for by their mothers for more than three years until they are subadults, and they are fully grown by the fourth year. Liopleurodon hesperos can live to be around 50 years in the wild, although it can live longer in captivity, with individuals reported to live around 70 years. Unlike (most) modern-styled cetaceans, Liopleurodon hesperos is extremely tolerant to life in captivity and has low stress if properly cared for, making it a suitable animal for aquarium parks and a good replacement for killer whales in captivity, due to its adaptability to life in captivity and remain very docile, friendly, and playful towards humans and other sapient species. The conservation status of Liopleurodon hesperos is Vulnerable due to some pollution and persecution, however, thanks to the conservationists, Liopleurodon hesperos is a protected species and the population trend of Liopleurodon hesperos is increasing.
