Pictured: Sea cucumber, North Sulawesi, Indonesia, Pacific Ocean
This spiky sea-cucumber looks like a giant slug, but it is in fact collected by divers to sell as a delicacy believed to have many health benefits.
The huge marine animal is around 1m long and uses its spiked tentacles to feed.
A villager, known locally as a 'sea gypsy,' can be seen collecting sea cucumbers in a netted bag as he walks 30m underwater on the sea bed.
The sea cucumbers are then dried, usually by the villagers who find them, on the sand for preservation before they are sold.
Sea cucumbers are seen as a delicacy of high value throughout east and southeast Asia, particularly in China
These particular sea cucumbers were found around islands in the Pacific and Indian Oceans, which photographer Franco Banfi visited.
