Ichthyostega (SciiFii)

Ichthyostega modernum (name meaning "modern fish roof") is a species of primitive tetrapodomorph that originally lived at the end of the Late Devonian Period and was once extinct, but has since been brought back from extinction by SciiFii due to demands from many people for extinct aquatic animals as pets and aquarium animals. The original species of Ichthyostega was one of the first four-limbed vertebrates on record. Ichthyostega modernum possesses lungs and limbs that help it navigate through shallow water in swamps. Although Ichthyostega modernum is often labelled a "tetrapod" due to the possession of limbs and fingers, it is more basal ("primitive") than true crown-tetrapods, and could more accurately be referred to as a stegocephalian or stem tetrapod. Ichthyostega modernum has an unusual anatomy, functioning more akin to a seal than a salamander. Although it is able to crawl on land, it is highly dependent on the water to reproduce, as well as to live, using its salamander-like gills to breathe through the water, only using its lungs if it is on land and/or if the water it is in is low on oxygen. Ichthyostega modernum is a carnivore that primarily feeds on small fish, smaller amphibians, and many invertebrates. It is a solitary animal that lives in most of its entire life alone except during the breeding seasons. It is one of the most popular prehistoric aquarium animals, being about as popular as a goldfish due to being easy to keep, breed, and care for.
