Akiflora

The Akiflora is a helpful, gentle creature. It has no wings and prefers to hop around areas. The thing is that it gets eaten on purpose. When a larger creature swallows one, that Akiflora will use its special flower on its back to respirate, digest, circulate, etc to support their host. Since they mate for life and require a warm and cozy environment, they stay inside the host creature, often for life.
