Odd though it may seem to those of us who lead more pedestrian lives, primarily landbound, there are those for whom shark watching is a regular activity, and for some a passion verging on addiction.
This is a book about that tribe and the sharks they watch; how to do it well, how to do it safely and where to do it. It all seems quite remarkable to me.
Austin Gallagher is eminently qualified to lead us on this quest. He is a distinguished shark biologist as well as being a keen diver, motivated by the pursuit of scientific truth while not denying the thrill of intimate association with ancient creatures, where lethal encounters are always a possibility. Unlikely and rare, yes, but the threat is always present - and on their terms.
Vigilance and respect are the cardinal rules of diving with sharks. What starts out as a routine dive in a familiar location can rapidly become dangerous; it is vital to know when it's time to get out of the water.
The safety of the shark is paramount, no less than the health and well-being of the diver. You wish to go home and have dinner, not become one!
The first sections of the book provide you with a wealth of information about the origins of these top ocean predators, their lifestyles and locations, shark photography and the ways that you need to act to ensure a safe outcome for both shark and human. The pages are gloriously illustrated and reveal scenes that most of us will never observe first hand.
The species accounts are masterfully done, with text on the left, and a picture, identification keys, a range map, notes on distribution and hot spots on the right.
Were I a diver, I would find the location directory immensely useful. It is a gazetteer of diving locations around the world, organized by continent.
Sadly, as is the case with all organisms on Earth the future is uncertain. There are success stories in Marine Protected Areas (MPAs), but recovery of these ancient creatures is slow. We must cling to hope, but optimism does not deny facts, and we are changing the oceans in ways that have far-reaching and long-lasting consequences. We continue to assault the seas with staggering amounts of garbage, they are heating up, becoming more acidic and currents that regulate the temperature of the Earth are in danger of being disrupted.
I was on the Island of Eleuthera in The Bahamas in February, and the sharks there have tested positive for drugs, including cocaine and painkillers. How are other marine organisms affected? What does this signal for humans? We are not immune from the havoc being wreaked on the oceans. Sharks are consumed by humans around the world and bioaccumulation of toxins is a real threat.
The book illustrates magnificently the glory of ocean life, and the joy to be derived from diving with top predators. Let's hope we can come to our senses - and soon - to make sure we do not lose it.
Or is it already too late?

Sharks are beautiful creatures. And essential to aquatic life.
ReplyDeleteHumans kill them without reason, it's sad....
Thanks David for sahring this interesting book !
Have a lovely weekend !

We chop off their fins and toss them back into the ocean. Sheer cruelty in addition to profligacy. All for a bowl of soup.
DeleteDon't think I am adventurous enough to do a shark diving...still, this can be quite helpful for those who are interested in learning more about sharks.
ReplyDelete...an activity that is foreign to me.
ReplyDeleteTo most of us, Tom.
DeleteI'm with you. It's strange (perhaps not the right now) to think that there are people who are shark watchers. But I bet they are very impressive to see. Especially those bigger and maybe more ferocious than sand sharks. I do feel bad for sharks though as they are really misaligned creatures. Happy new month David. Hope it's a great birding month for you as all the summer avians come back. hugs-Erika
ReplyDeleteI need the facts about sharks, the authentic knowledge and the ideas too. I watched a Steven Spielger movie once many years ago. It was enough to convince me that I would never do that again.
ReplyDeleteAustin Gallagher's "instructions" for sharks was interesting to read for me.
You can only get to know them with the right knowledge and care.
I hope that it is never too late to do anything, to start or continue.
This seems like a wonderful book to me, David.
ReplyDeleteMankind is destroying all life on Earth through the way we live these days, including the sharks and other fish species swimming in the oceans.
All the best, Irma
There are many publications about sharks, and I'm certain they rarely disappoint. This one definitely looks very good. Also, pretty clever of the publisher to put examples of how the descriptions actually look on the back cover.
ReplyDeleteThis one is filled with practical advice.
DeleteIt's absolutely crazy that sharks test positive for cocaine! The oceans have become a garbage dump, and I hope that sharks survive in the future too.
ReplyDeleteHugs and kisses, Marit
Crazy, yes. Surprising, no. It is tragic, Marit.
DeleteSharks have been much maligned. Thanks to books and posts like this one, we can see their true worth. Thanks for another great book review.
ReplyDeleteIn the 1970's we did do deep sea fishing and got a shark along with a Marlin, and some Mahi Mahi. The only fish we did not eat was the shark, but there were other locals that asked for the meat.
ReplyDeleteI didn't know much about them at the time, but they are fascinating creatures.
Our oceans are in peril as well as the aquatic life in it.
I'm fascinated with sharks. As with so many other water/ocean dwellers humans have destroyed their habitat and now we have sharks that test for cocaine!!!! My heart breaks for everything on earth. Thank you for sharing this book.
ReplyDeleteI've only seen a shark in the wild once. It was in the Gulf of Mexico as it swam alongside the boat I was in. I'm not even sure of which variety it was but it was definitely an exciting moment of viewing. Sharks are fascinating creatures and they fulfill an important role in the environment.
ReplyDeleteSo we're more of a threat to them than they are to us? well, I forgive them for the nightmares they gave me in my childhood, jaja
ReplyDeleteHappy New Month of May!

That would be a very interesting book to have. I'm amazed that sharks have tested positive for drug! Hard to believe for me.
ReplyDeleteI remember swimming with very small sharks at Lord Howe - it was a remarkable experience, and those sharks were small!
ReplyDeleteHope all is well.
Cheers - Stewart M - Melbourne
I have never been in the water with them but have seen them in several parts of the world. They inspire respect!
DeleteI rather read about a shark than swim alongside it.
ReplyDeleteI am not a great fan of the water, sharks or no sharks.
DeleteSharks are wonderful and interesting. Me and my daughter watched a show about them and afterwards she wanted a pet shark!!! I got her a stuffed toy shark. :-D
ReplyDeleteI'm in the "too late" gang. We've really messed up our home and it's only gonna get worse. :-(
Sharks are extraordinary animals, and myths are being demolished the more is discovered about them. Respect is paramount when engaging with wild animals wherever they are to be encountered. Experts should be respected and their advice followed. Personally, their films and discoveries are more than enough for me.
ReplyDeleteI would never have thought that sharks would test positive for drugs.
ReplyDeleteNor did any of us, but with the amount of junk we are dumping into the oceans it hardly comes as a surprise.
DeleteI've never much been into sharks, except to be aware if ocean swimming. Jaws has that effect on a person!
ReplyDeleteI waver between thinking we can fix things and thinking it's too late. Sometimes I think it would be better if we humans kill ourselves off; I hope that doesn't result in killing everything else off, too.
ReplyDeleteThere's the ever-present threat of nuclear war, the climate crisis and now the possibility that AI will exceed our intelligence and manipulate us, so I think there is a good chance we will not survive for too much longer.
DeleteThis is not a bird, but very interesting. just kidding!
ReplyDeleteLooks like a must-have book for shark lovers or anyone who is fascinated by oceans and the creatures that inhabit them.
ReplyDeleteWe have Marine Protected Areas here, but the current administration makes it very difficult to keep them protected. I have a rather pessimistic outlook on the future and would answer your concluding question with a "yes, I think it's already too late" (and hope that I am wrong). Big hugs, my friend - Carola
ReplyDeleteSounds like a good read. The only sharks I have seen were on nature shows. I find it incredible that sharks have tested positive for drugs.
ReplyDeleteDear David,
ReplyDeleteBeneath the waves where shadows glide,
Ancient hunters rule the tide;
With awe and caution, hearts must meet
Those silent fins in oceans deep.
For beauty swims where danger stays,
A fragile world in troubled days …
May wisdom rise as swiftly as fear,
So sharks, and seas, remain with us here.
John
PS What a great post and book review.
Your love of nature and knowledge
of science makes your blog one of my
best-ever finds in the blogosphere. And
thank you for your kind words on my blog.
Best regards to you!
Cocaine and painkillers in sharks? Good grief. The book sounds good though I wouldn't want any part of swimming with them. Have a grand one, David.
ReplyDeleteKuten Kirk kirjoitti, luen mieluummin haista kuin uin niiden kanssa. Kiitos David kirjan esittelystä, se on varmasti mielenkiintoinen ja herättelevä teos.
ReplyDeleteEs apasionante el mundo de los tiburones y muy interesante este libro que explica su localización y la manera de tratar con ellos en el caso de ser buceador buscador de esos extraordinarios animales.
ReplyDeleteCom dices, David, el mar está tan contaminado que el futuro se presenta incierto, no sólo para los tiburones, sino para toda la fauna y vida marina.
Un libro más que interesante a tener en cuenta. Gracias por la reseña.
Muchos besos y feliz semana.
