Andy Torbet joins the growing ranks of seagrass advocates , doing his bit to help look after one of our most secretive sea creatures

In this column I recently wrote about my work as an Ambassador for The SeaLife Trust and my visit to The Cornish Seal Sanctuary . The Trust supports a long list of projects and other organisations , and recently I was fortunate enough to visit one such scheme seeking to protect an often-overlooked marine habitat , and one surprising creature that relies on it .

I confess that when I began diving , and for much of my underwater career , I overlooked the meadows of seagrass . As a zoologist

Examining seagrass roots
Chris Brown of Sea Life UK ( left ) explains how traditional anchors scour the seabed and seagrass habitat by initial academic training , I sought the bigger animal species and left the grass to the botanists .
Whereas coral reefs are often thought of as the rainforests of the sea due to their rich biodiversity , from a globally-important carboncycle point of view seagrass has far more in common with the great jungles than the reefs .
In fact , an area of seagrass will absorb 35 times more carbon than the same size area of rainforest . Although it only represents 0.2 % of the ocean floor , it accounts for 10 % of total oceanic carbon sequestration . But that ’ s not all . Seagrass fields also prevent coastal erosion and provide important nursery grounds for a wide variety of fish and invertebrate species , as well as being home to some very rare creatures . And it was the latter I had come to see . The seahorse .
Few people in the UK are even aware that we have native seahorse species around our shores . Our Spiny and Short Snouted Seahorses are under threat from habitat loss
