European seahorses, once plentiful in the shallow lagoons of the Ria Formosa in Portugal, suffered a dramatic decline a few years ago. On the Costa Brava sightings by scuba divers are infrequent, but last year research dive volunteers were lucky enough to find a pair of the species Hippocampus guttulatus.
This has prompted us to plan a full population survey in a sheltered bay where the seagrass habitat is threatened by seasonal pleasure boat anchoring. We want to find out how many there are and which environment they prefer - since those that we encountered were, suprisingly, on sand.
We seek dive volunteers to join Kenna Eco Diving as research divers this summer to assist with the seahorse survey and other marine conservation research.

One of the key species that we are monitoring for the Silmar Project is Hippocampus guttulatus, the Long-snouted seahorse, which has become increasingly rare in the Mediterranean over the past decade. Last August (2013) a volunteer found an intact skeleton of a Long-snouted seahorse.
Then, in October, we came across not just one, but two Long-snouted seahorses! They turned out to be a male and a female. They weren't in the seagrass, as we would have expected, but out in the open on the sand, with only some algae for cover.
