Megalograptus (SciiFii)

The greater sea scorpion (Megalograptus serket), or simply sea scorpion, is a species of large sea-going Eurypterid (a group of arthropods more closely related to horseshoe crabs than terrestrial scorpions) that originally lived in the oceans during the Last Ordovician Period as an extinct species of Megalograptus and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern Indian, Atlantic, and Pacific Ocean to help boost biodiversity. The greater sea scorpion is a rather large arthropod, growing to be around 78 cm (31 in) in length. It is one of the best known sea scorpion species, due to its long appendages on the front of its body with many of the spines, which are used to rake through the sediment to find prey. Like all other sea scorpions, the greater sea scorpion is a carnivore, mainly feeding on trilobites, fish, small horseshoe crabs, mollusks, crustaceans, and other animals smaller than itself. Unlike terrestrial scorpions and just like most other sea scorpions, the greater sea scorpion lacks a stinger and instead has paddle-like legs and a fluke at the end of its tail for swimming through the water. It not only has arthropod lungs like most other arthropods, including most other sea scorpions, but also gills so it could spend most or its entire life underwater, except during breeding seasons (when female greater sea scorpions come onto the shore to reproduce en massenin a manner similar to horseshoe crabs) or if there are dead animals washed up on beaches, where greater sea scorpions can scavenge on the remains. The conservation status of the greater sea scorpion is Least Concern due to successful conservation efforts, the greater sea scorpion's wide range, and its tolerance to most of the human activities, including being able to adapt to life in the coastal cities, suburbs, and public beaches.
