20. Poseidon's Steed: The Story of Seahorses, From Myth to Reality by Helen ScalesIn this post's title, Philip Henry Gosse was discussing a pipefish he had collected at the Devonshire seacoast (western England) sometime between 1852 and 1854, but he could just as easily have been talking about their cousins, the seahorses. Seahorses have fascinated me since I was a child, so I was overjoyed to find this "little book" at my local library. In her opening chapter, Dr. Scales questions about the seahorses, also known as hippocampus, "Should we presume these odd-looking creatures were designed by a mischievous god who had some time on her hands?"
Seahorses have fascinated land-walkers from the earliest times, evidenced by their likenesses being found on Lydian jewelry, in Greek and Roman mythology, and on Pictish stone carvings. Scales's book, while only 193 pages of text, is crammed to the hilt with information about these intriguing little fish, including mythology; taxonomy, evolution, and relatives (pipefishes and pipehorses); traditional medicine (especially Chinese); the aquarium trade, starting with how aquariums came to be in the first place (Roman water gardens stocked with edible fish to assure guests will have a fresh meal); and conservation concerns. This book is easily read by the non-scientist and is thoroughly engaging. Included at the end of the book is a complete bibliography of the author's sources and an appendix with brief descriptions of all the known
Hippocampus species. Several plates are found in the middle of the book showing a few remarkable individuals as well as ghost pipefish and leafy and weedy seadragons.
In the epilogue, Scales points out that the oceans and the coral reefs are not dependent on seahorses to be healthy or to continue to function. Hippocampi are not keystone species, but they are an aesthetic wonder and an intrinsic joy for millions of people, regardless if they've been seen in person or not. Their loss would be felt if for no other reason than our grandchildren would listen incredulously as we described them:
Imagine what it would be like if all we had to tell our grandchildren were stories of a time when there used to be wonderful creatures called seahorses living wild in the oceans. They looked like miniature horses with rolling eyes and tiny monkeys' tails. It was the males that had babies -- no animals do that anymore -- and they changed color as if by magic and danced elegant dances every day with their faithful partners. If stories were all that were left of the seahorses, I don't suppose anyone would believe us.
