I’ve recently received a copy of Jim Abernethy’s book ‘Sharks - Up Close’ which is simply superb. Many of us that have had the great privilege of seeing and photographing sharks know what magnificent creatures they are, but the plight of their plummeting numbers worldwide is not well known. Sharks’ role in keeping marine ecosystems in balance is critical to the health of the oceans but relentless overfishing threatens their very existence. The photograph above of Scalloped Hammerheads was taken in the waters of the northernmost Galapagos islands, Wolf and Darwin. When I look through my shark photographs now, I treasure the moment and wonder are they still there.
