Sandeels (Credit Mark Thomas)
The gravel and sandy plains of Markham’s Triangle provide a home to thousands of sandeels, which burrow in the sediment to escape predators, such as harbour porpoise.
The sandeels here form a key food source for grey and harbour seals as well as harbour porpoise, regularly spotted passing through the area.
Located 137km offshore from the Yorkshire coast, the seafloor ranges from 30-50 metres in depth making it a relatively shallow area. The seafloor consists of both coarse sediment and sand, interspersed with small patches of rock and gravels. This supports many creatures that burrow within or camouflage against the sediment, such as polychaete worms and bivalve molluscs. The sandeels here form a key food source for grey and harbour seals as well as harbour porpoises, regularly spotted passing through the area.
