Fluorescent sea squirts could help cancer research
Scientists are hoping fluorescent anemones that live off the east coast of Scotland will have a role to play in cancer research.
Proteins extracted from fluorescent jellyfish are already being used to track cancer cells.
Researchers in St Abbs are investigating whether the fluorescent sea squirts will be also able to light up microscopic cellular activity that would otherwise be invisible to the human eye.
A team from the BBC Two programme Britain's Secret Seas was given special permission to do a night dive and see the anemones that live there.
Britain's Secret Seas continues on Sunday, 15 May on BBC Two at 2000 BST.
