Ocean Sanctuaries, San Diego’s newest ocean-related nonprofit currently has two citizen science shark monitoring programs which allow local divers to document their encounters with various species of shark.
You can log encounters with Sevengill Sharks here: http://oceansanctuaries.vm-host.net/sevengillshark/submit.jsp
Any non-Sevengill shark species can be logged here (with National Geographic’s ‘Fieldscope’ citizen science tool): http://sharksofsandiego.fieldscope.org/v3
At least one photograph must accompany each encounter logged.

Silent Reef Keepers: The Fight to Save the Caribbean Reef Shark
The Kingdom of the Netherlands will ask for increased protection for the Caribbean reef shark during next month’s Conference of Parties for the Cartagena Convention (COPs) on Aruba. Caribbean reef sharks play a critical role in maintaining a healthy reef ecosystem and building resilience within the oceans. This increased protection is critical for ensuring a sustainable future for this iconic species.
The Caribbean Sea is renowned for its crystal-clear waters, vibrant coral reefs, and a dazzling array of marine life. Among the charismatic inhabitants of this underwater paradise is the Caribbean Reef Shark (Carcharhinus perezii), a species that plays a crucial role in maintaining the health of coral reef ecosystems. In the Dutch Caribbean, these apex predators face mounting threats, but there is hope on the horizon. At the upcoming Conference of Parties for the Cartagena Convention (COPs), the Kingdom of the Netherlands will seek increased protection for these magnificent creatures by listing this species on Annex III of the SPAW Protocol. Annex III includes plant and animal species which require additional protection to ensure this species is able to adequately recover their populations in the Wider Caribbean Region.
Caribbean reef sharks thrive in warm, tropical waters of the Caribbean region, with a distribution range that stretches from Florida to Brazil. This species is one of the most encountered reef shark species throughout the whole Caribbean Sea. Growing up to 3m (9.8ft) in length, this shark is one of the largest apex predators in the reef ecosystem and is at the top of the marine food web, having only a few natural predators.
In addition to being of great economic value, as shark diving is a major draw for divers from around the world, this species is also critical for maintaining balance within the reef ecosystem. Their presence helps regulate the population of smaller prey species, which in turn, prevents overgrazing on seagrass beds and coral reefs and eliminates sick or weak fish from the population. This balance is essential for maintaining the health and diversity of the entire coral reef.
Despite their ecological and economic significance, Caribbean reef sharks in the Caribbean face numerous threats that have led to a population reduction estimated to be between 50–79% over the past 29 years. In the (Dutch) Caribbean this is mainly caused by:
Habitat Degradation: The degradation of coral reefs and seagrass beds due to climate change, pollution, and coastal development has a direct impact on the availability of prey for these sharks. Loss of habitat reduces their ability to find food and shelter.
Overfishing: Overfishing poses one of the most immediate threats to Caribbean reef sharks. They are often caught incidentally in commercial fisheries, where fishermen are targeting other species, or intentionally, where they are sought after for their fins, used in shark fin soup.
A Call for Increased Protection
There are different organizations and individuals working to protect sharks and their habitats in the Dutch Caribbean. A significant milestone was the establishment of protected areas such as the Yarari Marine Mammal and Shark Sanctuary between Bonaire, Saba and St. Eustatius. Another milestone was in 2019 when the Dutch government adopted an International Shark Strategy. The strategy sets out which protective and management actions for sharks and rays are to be taken by the government in all seas and oceans where the Netherlands has influence (including the Dutch Caribbean). Additional efforts are still needed to create more marine protected areas, enhance enforcement, reduce pollution in the ocean, and promote sustainable fishing practices. These species know no (political) boundaries and their protection requires broadscale conservation efforts within the Dutch Caribbean and beyond.
The Caribbean reef shark is a species of paramount importance to the (Dutch) Caribbean’s coral reefs. With the extra protection being requested during the next COPS meeting in Aruba, there is hope that this species will have a healthy future. By recognizing their ecological significance and the challenges they face, we can work together to ensure a brighter future for the Caribbean Reef Shark in the Dutch Caribbean and beyond.

Dive Pirates Foundation nominated for DEMA’s Community Champion Award, asking for DEMA Members to vote now!
Dive Pirates Foundation is proud to announce it has been nominated for DEMA’s 2023 Diving Community Champions award. The Foundation is asking all DEMA members to support the crew and vote to recognize the great efforts achieved in 2023!
Specifically, DPF is being recognized for this year’s “Find Your Inner Treasure” effort, which brought the world of scuba diving to 6 adults living with disabilities. Through this effort, the recipients – 5 of whom are military veterans – were equipped fully and trained by their local dive shops before enjoying a week-long dive trip to Cayman Brac Beach Resort. While at the resort, DPF provided additional volunteer instructors and adaptive buddies for all participants to dive adaptively alongside industry professionals and returning adaptive divers alike. For many of the new divers, these dives were their first open water diving experiences. By the end of the week, all new divers had completed more than a dozen open water dives, with some also earning their open water diver certification.
However, Dive Pirates’ “Find Your Inner Treasure” effort also provides something much more than a scuba diving trip: freedom. The new divers frequently used this word to describe the feeling of scuba diving, with many expressing that they thought diving was unattainable for them with their disability. For them, this trip was much more than a vacation. It was a confidence boost and validation of their ability.
New participants also found themselves welcomed into the Dive Pirates family and the dive community at large. Throughout the trip, DPF provided its participants new and old with fun events at the resort in order to build camaraderie and to promote a welcoming, inclusive environment for the 6 new divers. With the new members eager to return for future dives, as well as 8 past recipients, one stowaway adaptive diver, and other divers making this their vacation volunteer effort resulting in 64 travelers, 2023 marked another successful year for the Dive Pirates Foundation.
Now, DPF needs you to vote so they can be recognized for their amazing work! Voting closes October 12, 2023, at 4:00 pm US Pacific Time. DEMA members can vote for DPF here.
The Dive Pirates Foundation a 501(c)3 organization, positively impacts the lives of its recipients; injured military, first responders, law enforcement and others with mobile disabilities, by welcoming them into adaptive scuba diving which fosters accomplishment, self-worth and community. The Foundation trains, equips and conducts dive trips year-round to calm, warm-water locations for the safety of those with spinal cord injuries, networking with facilities willing to empower all participants with compassion and adaptation for a positive experience diving, team building and networking.
