The eyespot cuttlefish (Sepia lycidas) is a medium-large cuttlefish inhabiting the Eastern continent. Unlike other cuttlefish of the area, it isn't very well adapted to hot climates and as such, its range is limited closer to the coasts of the continent away from the scorching deserts. It is a visually impressive cuttlefish with vibrant blues and greens, as well as unique eye-like stripe patterns across the body. Although poorly equipped for the deserts, its territory reaches further north than that of any other cuttlefish in the area.

The glitter squid (Sepioteuthis lessoniana) is a type of reef squid that inhabits the Eastern continent, and one of the only two squid species on the eastern coast. Compared to the western reef squid, the glitter squid has bolder and more defined iridescent stripes across its body, but its visual displays are slightly less elaborate. It is an extremely numerous and widespread squid in its area.

The eastern squid (Todarodes pacificus) is the most numerous squid species of the Eastern continent. It is a highly social species that inhabits the coasts and Northeastern territories of the continent, not doing well in desert environments but having high population density in the colder climates. In coastal areas, the species is credited for the invention and rapid improvement of oceanic fishing, with something about 70% of their diet consisting of oceanic fish.
