Dwarf white shark (SciiFii)

The dwarf white shark (Nanocarcharacles vulgaris) is a species of small mackerel shark that originally did not exist, but has since been created by SciiFii and introduced throughout the world's oceans to help boost biodiversity. Despite its tiny size, the closest living relative of the dwarf white shark is the much more famous great white shark (Carcharodon carcharias). As its name suggests, the dwarf white shark is the world's smallest mackerel shark, growing to be up to 20–25 centimeters (7.9–9.8 inches), and with typical adult sizes ranging from 10–15 centimeters (3.9–5.9 inches). The other distinguishing characteristics of the dwarf white shark includee a slimmer body, slightly more elongated dorsal and pectoral fins, and smaller, more rounded teeth. Like other mackerel sharks, it has an anal fin, five gill slits, eyes without nictitating membranes, and a mouth extending behind the eyes. Due to its small size, it posses no danger towards living mammals, birds, or most reptiles or amphibians, but it can feed on other fish, crustaceans, worms, snails, small amphibians, and, unlike most sharks, commercial fish food. The dwarf white shark is non-migratory, and is able to tolerate pure freshwater and completely still waters, unlike most sharks, making it a very suitable aquarium pet, compared with its close relatives. The dwarf white shark tolerates members of its species extremely well, and up to around 15 individuals can be placed in a large household aquarium. The dwarf white shark is a very fast and frequent breeder and, in just 2.5 months after mating, can give live birth of up to around 30 tiny young at a time and, unlike most sharks, are not cannibalistic. The young of dwarf white sharks can reach sexual maturity at just 1 year and the species can live to be around 70 years. The conservation status of the dwarf white shark is Least Concern due to successful conservation efforts, the dwarf white shark's wide range and its tolerance to many of the human activities.
