A species of fish known as a lumpsucker was among “amazing” rare sightings made by volunteers taking part in a survey of the Cornish coastline.

Run by the Cornwall Wildlife Trust (CWT), the Shoresearch project is a five-day marine wildlife monitoring survey carried out over the autumn equinox spring tides.

This year the lumpsucker - so-called because of its lumpy skin and a sucker it uses to attach to rocks and kelp - was spotted at Polzeath, while other Cornish finds were a conger eel, a squat lobster and a corrugated crab.
