Trying to put some order around my photographs I was contemplating what the world must look like through some of the extraordinary eyes that the creatures have. The Molluscs, which include cuttlefish, squid and octopus all have variations on a curved slit. With a highly developed nervous system this aperture shape must detect motion in a direction that is aligned to a rapid strike, or maybe it is spot the outline of a predator passing nearby?
The tassel-snouted flathead peers through what look like a system of branching roots, while the Eastern Fiddler ray has rounded lobes on the iris.
Each has evolved for a specific purpose and yet quite beautiful to behold.
