Opalescent Eye of Toadie – Reflecting on refracted light

Here’s why I rave about our toadies’ amazing eyes when seen via facemask in shallow, sandy, near-shore areas. I see them mainly late, in summer and autumn, when they are at their most prolific.

Sunfish sightings in South Australia

Society member, Geoff Mower, recently sent us a message as follows: – “A few years ago I was travelling in New Zealand, and wandered in the late afternoon along Keri-Keri Beach, just north of Auckland.

I wrote an article about sighting a Numbfish, Hypnos monopterygium, at Semaphore Beach in our November 1991 newsletter (No.172).
