As the early morning light filters its way down into the shallow depths where this little creature lives amongst weeds and rocks, the male is on the lookout for its mate. Hidden from prying eyes, the enigmatic, almost shy seahorse looks out from its ocean hideaway assured that it’s cryptic camouflage will hide it from even the most determined predator.

I have spent the last 42 years studying seahorses around the world, and yet, I still find them to be one of the most extraordinary creatures to dwell in the ocean. In 2000 I set up The Seahorse Trust, not just to look at seahorses but also the marine world as a whole. It was founded by my wife Maxine Garrick-Maidment and myself after we co-designed and built two public aquaria, including our own in Exeter, Devon in the south of England, which we closed to join the team at the National Marine Aquarium in Plymouth, UK. Funding for the Trust’s work comes from donations, grants and a membership and seahorse adoption scheme.

Key to the success of The Seahorse Trust is our partnership approach and with this in mind we set up the Seahorse Alliance to bring together like minded organisations and projects all over the world. We now have links to 33 countries worldwide and are starting a new project in Jordan, in the autumn of 2019. Currently, we’re partnered with projects in Bermuda, Malta, Peru and Spain that are recording data. This is crucial due to the fact that information about these creatures is relatively scarce. For example, of the five species of pygmy seahorses currently on the IUCN Red List of Threatened Species, four are categorised as Data Deficient.

Maxine and I think it is important to look at the natural world as a whole and not just individual species. With this in mind, the Trust advises and runs a number of projects in the UK and abroad looking at the habitats seahorses live in, the various species that live there and the problems facing them. Predominantly, the problems they face are human-related – habitat loss, trade for curios, pollution, overfishing, bycatch and rising water temperatures all play their part. Of the few statistics that are available, one particularly shocking figure is that of the wild population of the Knysna Seahorse. It’s primary habitat, the Knysna estuary in South Africa, is a body of water heavily-used by humans. This species, that went from vulnerable status to endangered in 2000, is inferred to have declined by at least 50% in the past 10 years.

They are truly unique in the animal kingdom. Each and every morning the male seahorse patiently waits in his small territory for his partner – many species are seasonally monogamous – to arrive after sending out a chemical message of pheromones. By pumping his brood pouch, the pheromones seep into the water, drifting on the current and let the female know the male is waiting to start their shimmering courtship display that will reinforce the pairs’ bond for the breeding season.
