Activities in Zanzibar

If you’re a new diver, "Will a shark bite me?" is likely one of the first questions that crosses your mind. It's a common fear, often fueled by movies and the media. But the reality is, sharks are often misunderstood. Most shark species are shy, cautious, and simply uninterested in humans. In fact, you're far more likely to be struck by lightning or injured by a falling coconut than to experience a shark bite!

Sharks and their crucial role in ocean ecosystems

Sharks are apex predators, playing a vital role in maintaining marine ecosystem balance. By regulating the populations of other species, sharks help keep ocean life healthy and stable. Encountering one while diving is often a peaceful and awe-inspiring experience, with many divers considering it a privilege to witness these majestic creatures in their natural habitat.
However, it’s important to remember: sharks do have a mouth full of teeth! Always respect their space and follow safety guidelines underwater. After all, we’re the visitors in their world. With a good dose of respect for their environment, a dive with sharks is truly one of the most beautiful experiences a person can have.

The real threat to sharks

While sharks are often feared, humans are the biggest threat to their survival. An estimated 100 million sharks are killed every year due to overfishing, bycatch, and the demand for shark fins. This has pushed many species to the brink of extinction, with one-third of all shark species now considered threatened, and some populations declining by as much as 90% in recent decades.
Sharks are crucial for maintaining marine biodiversity. Without them, prey species can multiply uncontrollably, causing damage to coral reefs and seagrass beds, ultimately disrupting the entire marine food chain. Protecting sharks is not just about saving a species—it’s about preserving the health of the entire ocean.

Sharks aren’t interested in you – They’re interested in their prey

Humans often see the world from a human-centric perspective, assuming animals are just as focused on us as we are on them. With so many species in the ocean — fish, rays, turtles — it’s almost absurd to think that sharks specifically target humans.
Sharks have been around for millions of years, evolved to hunt fish, seals, and squid, not humans. Most shark "attacks" are cases of mistaken identity. Sharks, curious by nature, often test unfamiliar objects like divers with their mouths. However, sharks don’t see humans as a food source — they’re not interested in our lean, bony bodies.
The myth of sharks hunting humans has been perpetuated by movies and the media, fueling unnecessary fear. It's a reminder of how humans tend to place themselves at the center of every story — even in the vast, mysterious ocean. Instead of fearing sharks, we should admire their role in maintaining marine ecosystem balance.

Why we must protect sharks

Sharks are not mindless killers — they are essential to the health of our oceans. Without sharks, marine ecosystems would face collapse. Protecting them goes beyond saving a species; it’s about safeguarding the delicate balance of life beneath the waves.

Sharks in Zanzibar

Zanzibar may not be known for large pelagic species, but its dive sites offer incredible encounters with diverse marine life. Mnemba Atoll, located off the northeast coast, is a must-see for divers. While large pelagic species are rare, the crystal-clear waters here are home to a range of fish species, including white-tip reef sharks and stingrays. The visibility is excellent, making it ideal for divers of all levels.
For a quieter, more intimate dive experience, Tumbatu Island offers a hidden gem with coral bommies, sandy patches, and abundant small marine life. Although it’s not known for large pelagic species, rays and colorful reef fish make it a unique dive spot.
At One Ocean Dive Center, we organize trips to both dive sites around Mnemba Atoll, Stone Town, Kendwa, and Tumbatu, offering divers the chance to explore Zanzibar’s underwater treasures.
