Frequently Asked Questions

Nereus Expedition is a science-driven dive initiative focused on ethical marine exploration. We curate expeditions that blend underwater adventure with education, conservation, and storytelling.

Our trips combine meaningful wildlife encounters, scientific collaboration, and community partnerships — all while maintaining the highest standards of marine ethics.

Each journey highlights a specific ecological or behavioral focus — ranging from fish migration patterns to reef health assessments. We work closely with marine scientists and conservationists to bring purpose to each dive.

Our expeditions offer encounters with a wide variety of marine species — from tiger sharks and manta rays to reef fish, turtles, whale sharks and thresher sharks, depending on the location.

While nature is unpredictable, we work with experts and local guides to maximize chances of encounters. We believe every dive, sighting or not, adds to the bigger journey — however for tiger sharks in Fuvahmulah (Maldives), yes, we do guarantee the experience.

Not always. Each expedition has its own requirements. Some are open to Open Water divers, while others may need advanced certification and experience with deep or drift diving.

We work with trusted dive centers, experienced guides, and maintain a strict focus on dive planning, briefings, and surface support. Your safety will never be compromised.

We follow strict codes of conduct to avoid harassment or manipulation of marine animals. Interactions are guided by necessity, respect, and scientific rationale — not for entertainment or social media.

Sharks are naturally curious, not aggressive. Following the guide's instructions and respecting the sharks ensures a safe and rewarding encounter.

Nereus was founded by Mohd. Maroof, a cybersecurity professional-turned ocean advocate, whose personal journey from the shorelines of Mumbai to the deep sea shaped the mission of the company: to bring science and soul into diving. He leads all the expeditions.

Once you book, we'll guide you through everything — gear, physical readiness, environmental briefings, and how to mentally and ethically prepare for an immersive dive experience.
