Jason deCaires Taylor's underwater exhibition in Grenada in the West Indies has attracted a lot of attention.
The artist says he seeks people who have a lot of character to pose for his sculptures.
The Un-Still Life uses the traditional tableaux as its inspiration but the living coral inhabiting the art means the work is constantly changing.
Fall from Grace is a lifesize sculpture of a man riding his bike - an activity more likely to be seen on land rather than under the sea.
The artworks can take weeks to complete on land before they are submerged to their final resting place.
The plain faces of the models begin to change colour and even shape as the marine life takes hold.
It is hoped that divers and snorkelers will keep away from natural coral reefs and instead be attracted by these with man-made originals.
Although humans models were used to create this Vicissitudes sculptures, they begin to look alien-like.
What are these?
