Ammonite (SciiFii)

The ammonites (Gaudryceras sp.) are a genus of cephalopods belonging to the family Gaudryceratidae that originally lived during the Cretaceous period, from Albian to Maastrichtian stages (105.3 to 66.043 Ma) as extinct species of Gaudryceras and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the world's oceans to help boost biodiversity. These cephalopods are fast-moving nektonic carnivores that primarily prey on small fish, squid, octopuses, snails, crustaceans, and sea urchins. The ammonites are small-to-medium-sized, depending on a species, ranging from 1 foot (0.3 meters) long in the smallest species to the largest species growing to be about 2.3 feet (0.7 meters) long. Like squid and octopuses, ammonites are prey for many oceanic predators such as sea otters, sharks, mosasaurs, whales, and among others, and are also economically important food sources for people due to an increasing demand for ammonite tentacles and eggs.
