Fresh calls have been made for "environmentally friendly moorings" to be used off the Dorset coast in a bid to increase seahorse population.
The appeal by the Seahorse Trust comes after about 50 short-snouted seahorses were discovered recently off Bournemouth, which it described as "absolutely incredible".
In total, 20 were sighted off Dorset last year.
Trial moorings at Studland Bay were put on hold in 2013.
