Sal Island Sharks, Sea Turtles & Diving Guide
Sal Island Marine Life Guide: Sharks, Sea Turtles & Diving
The Reality of Shark Bay (Baía dos Tubarões)
Shark Bay is one of Sal's most talked-about experiences, and also one of the most misunderstood. Many visitors arrive expecting something far more dramatic than what actually happens. Here's what a visit really involves.
Setting Expectations: What You Will (and Won't) Do
The Reality. At Shark Bay, you stand knee-deep in shallow tidal water and watch juvenile Lemon Sharks swim around your legs. The sharks are young, mostly less than a metre long, and move through the clear water in small groups. It's a calm, quiet, and genuinely special wildlife encounter, not an adrenaline sport.
What It Is NOT. A visit to Shark Bay does not involve open-ocean swimming, deep-water diving, or iron cage diving with Great Whites. If you've seen dramatic shark-diving footage from other parts of the world, set those images aside. The magic here lies in how close and natural the encounter feels, not in its danger.
Why Lemon Sharks Gather Here
A Natural Shark Nursery. Shark Bay's shallow, warm, rocky bays serve as a nursery for young Lemon Sharks. The shallow water protects the juveniles from larger ocean predators, including adult sharks, while they grow. As they mature, the sharks move out into deeper water, and new generations take their place.
Essential Practicalities & Gear
Mandatory Water Shoes. The seabed consists of sharp volcanic rock and is home to sea urchins, so protective footwear is essential. Water shoes or Crocs can be rented at the site for €2.00 – €3.00, or you can bring your own.
Tidal Timing. Visiting during low tide generally offers the best water clarity and the closest encounters with the sharks, since the calm, shallow water makes them easier to see. Organized tours plan their stop around the day's conditions, and if you're visiting independently, it's worth checking the tide times before you go.
Responsible & Ethical Shark Watching
The sharks at Shark Bay are wild animals in their natural nursery. How visitors behave directly affects their wellbeing, and whether this unique experience will still be possible for future visitors.
Do Not Touch or Feed
Hands Off. Touching, picking up, or feeding the sharks is strictly prohibited. Handling stresses the animals, can damage their skin, and changes their natural behavior. Feeding teaches them to associate humans with food, which is harmful for both sharks and visitors. Watch, photograph, and enjoy, but keep your hands to yourself.
Footwear & Walking Etiquette
Move Slowly and Carefully. Walk slowly through the water to avoid stepping on sharp rocks and sea urchins or disturbing the seabed. Sudden movements and splashing scare the sharks away, while calm, patient visitors are usually rewarded with the closest encounters.
Supporting Local Guides
Choose Official Guides. Working with official local guides helps protect both visitors and wildlife. Guides monitor visitor safety, make sure the rules are respected, and share knowledge about the sharks and their habitat. Your visit also supports the local community that looks after the site.
Turtle Conservation & Night Tours
Every summer, Sal's beaches become one of the most important nesting grounds in the Atlantic for Loggerhead sea turtles. Watching a turtle nest or hatchlings reach the sea is an unforgettable experience, and one that comes with a real responsibility to protect them.
Nesting Season (July to October)
Turtles Coming Ashore. Between July and October, female Loggerhead turtles (Caretta caretta) come ashore at night to lay their eggs on Sal's protected beaches, such as the Costa da Fragata and Kite Beach area. Each female digs a nest in the sand, lays her eggs, covers them carefully, and returns to the ocean. The same turtle may return several times during a season to lay more nests.
Hatching Season (September to December)
Baby Turtles Heading to the Sea. Around two months after the eggs are laid, the hatchlings emerge from their nests, usually at night, and make their way across the sand to the ocean. It's a fragile journey, and only a small number of hatchlings survive to adulthood, which makes every protected nest important.
Strict Turtle Protection Rules
Red Light Only. On night tours, white flashlights, phone torches, and camera flashes are not allowed. Bright light disorients nesting females and can lead hatchlings away from the sea. Guides use red light, which is far less disruptive to the turtles.
Keep Your Distance. Never touch adult turtles or hatchlings, and keep a respectful distance at all times. Disturbed females may abandon their nesting attempt and return to the sea without laying eggs.
Book Certified Conservation Guides. Book turtle tours exclusively through certified conservation guides, such as those working with Project Biodiversity. Certified tours follow strict protocols, limit group sizes, and help fund local conservation efforts, with prices typically around €25.00 – €35.00 per person.
Snorkeling & Scuba Diving in Sal
Below the surface, Sal's volcanic coastline creates a world of caves, rock formations, and shipwrecks. Whether you snorkel from the beach or dive deeper, there's plenty to discover.
Top Snorkeling Spots
Santa Maria Bay Pier (Pontão). The area around the pier and the shallow reef zones in Santa Maria Bay are the easiest snorkeling spots on the island, reachable straight from the beach. Fish gather around the pier's pillars and nearby rocks. Keep an eye out for boats and fishermen working around the pier.
Calheta Funda and Murdeira Bay. For calm marine life observation, head to Calheta Funda and Murdeira Bay on the west coast. Their sheltered water and rocky seabeds attract a wide variety of fish. Water shoes are recommended for the rocky entries.
Popular Scuba Diving Sites
Shipwrecks. The Santo Antão wreck in Santa Maria Bay is a popular shallow dive, teeming with fish that have made the wreck their home. Its location close to Santa Maria makes it an easy boat dive from the town's dive centers.
Volcanic Caves & Overhangs. Sal's volcanic origins have created dramatic underwater landscapes. Cave dives around Buracona and Regona, and the deep reef pinnacles of Tchuclassa, offer caves, overhangs, and rock formations for more experienced divers.
Expected Marine Species
What You Might See. Divers and snorkelers can expect to see stingrays, moray eels, nurse sharks, and trumpetfish, with occasional sightings of manta rays. Between March and May, humpback whales pass offshore on their seasonal migration, and lucky visitors may spot them from boats or even from the coast.
Frequently Asked Questions (FAQ)
Quick answers to the marine life questions visitors ask most often.
Are Lemon Sharks dangerous to humans in Shark Bay?
The sharks at Shark Bay are juvenile Lemon Sharks, generally shy and not considered a threat to calm visitors in these shallow nursery conditions. Treat them with respect as wild animals: don't touch, chase, or feed them, move slowly, and follow the instructions of guides and site staff. The bigger practical risk is the sharp volcanic seabed, which is why water shoes are mandatory.
Can I go turtle watching on my own without a guide?
No, you shouldn't. Sea turtles are protected by law in Cape Verde, and independent visits to nesting beaches at night can disturb nesting females and endanger hatchlings, especially if lights are used. Certified conservation guides know how to observe turtles safely and legally, and your tour fee helps fund their protection. If you come across a turtle or hatchlings by chance, keep your distance, turn off all lights, and report it to a local conservation organization.
Is Sal Island good for snorkeling directly from the main beach?
Yes, reasonably so. The area around the pier (Pontão) and the shallow reef zones in Santa Maria Bay can be reached directly from the main beach and offer a good variety of fish. For clearer water and richer marine life, however, Calheta Funda and Murdeira Bay are better choices, and boat snorkeling trips reach additional sites.
Do I need a diving license to explore the shipwrecks in Santa Maria?
It depends on the wreck and depth. Certified divers can join guided wreck dives with any dive center. If you don't have a license, you can try a Discover Scuba Diving experience (around €115.00), which includes pool training and a supervised open-water dive with an instructor. Some centers include shallow sites in these introductory dives, while deeper wrecks and cave dives require certification. Ask your dive center which sites are available for your level.
