Shark Species Guide
Sharks are some of the ocean’s most fascinating, misunderstood, and unforgettable animals. From the enormous Whale Shark to the unmistakable Great Hammerhead, the powerful Tiger Shark, the elusive Thresher Shark, and the reef-dwelling “walking” sharks of Raja Ampat, each species has its own behavior, habitat, personality, and story. For divers, learning to recognise these animals is part of what makes encountering them in the wild so rewarding.
At Bluewater Travel, sharks are a major part of the dive experiences we help travelers plan around the world. Our team has spent decades diving with sharks in the Galápagos, Socorro, the Bahamas, Fiji, South Africa, the Maldives, Indonesia, Australia, the Azores, and beyond. We know where particular species are most likely to be seen, when the best seasons occur, which destinations suit different experience levels, and which operators are committed to safe, responsible, and memorable encounters.
This Shark Species Guide introduces some of the world’s most iconic shark species, from famous bucket-list animals to smaller, lesser-known species that are just as remarkable. Whether you are dreaming of schooling hammerheads, a whale shark encounter, a tiger shark dive, or your first close look at reef sharks, this guide is a starting point for understanding the animals and planning the right dive adventure.

I develop and execute our SEO strategy, manage our content calendar and freelance writers, and make sure our destination guides, blogs and trip pages perform well in search while staying accurate and genuinely useful for divers.
Originally from the UK, I’ve spent much of my adult life living and working overseas, including Greece, Türkiye, Egypt, and across the Caribbean in Antigua, Margarita in Venezuela, Bonaire, Aruba, Curaçao, St Lucia and now Barbados. In my twenties and thirties I travelled as a professional watersports instructor and centre manager, running windsurfing, kitesurfing and sailing operations for hotels and specialist resorts before setting up and managing my own award‑winning watersports businesses in St Lucia and later in the UK.
Alongside this hands‑on watersports career I’ve held senior marketing roles for a variety of companies, from motorsport teams to outdoor activity centres and travel training providers. At Bluewater, I draw on this mix of practical experience and digital marketing know‑how to develop content that reflects real destinations, real dive conditions and real guest expectations. When I’m not working on the website, you’ll usually find me windsurfing, kitesurfing, diving or exploring new coastlines on a paddleboard or mountain bike.
