👉 Ichthyosiform, also known as fish-shaped or fish-like, is a type of mollusk that has three pairs of eyes and two pairs of legs. These eyes are arranged in an X pattern on the surface of the shell, while the legs are attached to the sides of the shell rather than the back. Ichthyosiforms are found in many different species, including some marine animals such as fish and sea urchins, but they also occur in freshwater environments where they can survive
