Seahorses are one of the most endearing, mystical, and beloved marine animals. Their strange shapes, vastly different appearances, and unique locomotion have mystified humans for centuries. To this day, however, our base of knowledge surrounding these amazing creatures is still relatively limited and we are just now really beginning to understand the depths of their existence. We have partnered with Project Seahorse on the 4ocean Seahorse Bracelet to help shine a light on the issues surrounding seahorses and to move the needle forward on science and conservation for generations to come.
Found throughout most of the world's oceans, seahorses are ambassadors for the ecosystems they inhabit and stand as flagship species for many marine ocean conservation issues that not only affect them but all the other species that surround them.
Unfortunately, the data we do have around seahorses does not paint the most positive outlook for their future. Currently, 42 seahorse species are included on the IUCN Red List; of those, 14 are listed as "vulnerable" or worse. And 17 are listed as "data deficient," which means we don't know enough about those species to determine their conservation status.
The threats seahorses face are many. Overfishing, destruction of habitat, bycatch, and ocean plastic pollution are all things that are having devastating impacts on many species of seahorses.
Seahorses have been used in Traditional Chinese Medicine going back millennia and are believed to treat everything from asthma to ED. While there is no scientific evidence backed by clinical trials, this belief is fueling a demand that undoubtedly is harming the sustainability of wild populations. Hong Kong is the epicenter of the global seahorse trade but most of the actual seahorses themselves come from places like Thailand, Philippines, Indonesia, and Vietnam –– all of which have export bans in place.
A recent research study conducted in early 2019 by the University of British Columbia, in conjunction with Project Seahorse, states that up to 98% of seahorses found in the global trade came from countries that already have bans! So even though all species of seahorse are listed in CITES Appendix II and are supposed to be regulated sustainably to keep wild stocks from being depleted, this revelation has exposed the fact that neither imports or exports are being enforced under the trade bans. And that means seahorse populations are still facing immense and unregulated pressure on their populations. This is a tragic way for millions upon millions of seahorses to die each year.
Destruction of Habitat and Bycatch
Every year vast swaths of ocean seabed are destroyed by the harmful fishing practice of bottom trawling for shrimp and other species. Using this method, a boat or boats drag a large weighted net along the seafloor and seahorses are indiscriminately caught up in the nets as bycatch. Hundreds of pounds of bycatch, including seahorses, can be pulled up on a single trawl. For every kilogram of shrimp caught by trawlers, as much as 10 kilograms of other marine life are caught as bycatch. Even if the trade of seahorses was stopped, this fishing would still continue and either way, these seahorses would end up dying.
Setting aside larger areas of ocean and greater enforcement of fishing exclusion zones are two things that could help with the fishing situation. Additionally, making sure that you don't eat shrimp that has been bottom trawled is the best way for you to make a difference for seahorses.
As we all know, ocean plastic pollution is becoming more and more of a problem. This is part of a growing trend especially in shallow seas surrounding human populations and cities where seahorses thrive. Plastic can suffocate the seafloor where seahorses live and push them out of their normal habitats. Unfortunately, they have sometimes even been seen clinging to this pollution as their home.
They can also mistake tiny microplastics for prey and ingest them accidentally causing internal damage to their fragile digestive systems. Seahorses sometimes only have milliseconds to suck up their prey and can eat as many as 3,000 crustaceans each day. Inevitably some of what they ingest is likely plastic.
At the end of the day, it is up to us to protect the habitats and ecosystems that these animals call home. The survival of seahorses depends on us and we must be determined to resolve their future. If not, we may lose many seahorse species forever.

Founded in 1996 by Dr. Amanda Vincent and Dr. Heather Koldewey, Project Seahorse aims to secure a world where marine ecosystems are healthy and well-managed. Their focus on saving seahorses, securing the world's shallow seas, and training conservationists to continue this important work is what they're all about. Check out some more of the great work they are doing inside.
From plastic rain to the world's largest beach cleanup to an ambitious plan to phase out single-use plastics, we've scoured the headlines for the newest and most noteworthy stories related to the ocean plastic crisis. Let's take a look inside.
Located about 40 miles south of San Franciso on California's central coast, Monterey Bay is home to one of the cutest and most iconic marine mammal species in the Pacific Ocean: the southern sea otter. Although this species is listed as "threatened," Monterey Bay continues to be one of their strongholds and much of the sea otters' success there can be attributed to the diligent work of our partner, the Monterey Bay Aquarium. Read on to learn more about their important work and to see more of these adorable creatures.
