The Heptile
A very unique Blish breaks uncharted ground in the Lichen Forest
235 MYH. By numbers, Blish officially known as Ichthyopterans make up the most numerous terrestrial species by numbers with several thousand species outranking the Terra Squids by the number of living representatives.
However, most of these Ichthyopterans fly under the radar as most of these warm-blooded volant Actinopterygians retain a variation of the same basic body plan that vaguely looks like an AI-generated Pterosaur.
Of course, there are some Blish that break this trend. Flightless Blish of the Cryptoland Islands or the Rapducken on the mainland that resemble Maniraptor dinosaurs and marine species that resembled Icthtyosaurs funnily enough.
