Senocular is most likely a word beloved of arachnologists who study the Sicarius hahni, known to its friends as the six-eyed sand spider. Very few others would have any real reason to use it, as senocular means possessing six eyes. Etymology, from Latin Seni (six each) + Oculus (eye).

“The Colonel beat the ground in futile impotence. The three cats had outsmarted him once again. He knew they would be just outside the perimeter regarding him. And there they were! Three motionless silhouettes in the night, a senocular statue with mocking lambent eyes.”
