moult

As lobsters grow, they moult their hard exoskeletons—often eating them—which means that they can reach astonishing sizes.

It begins: 'Moult vaut mieux pleure-chante que ne fait chante-pleure.'

The larvae moult three times, and after each moulting appear yellow, soon changing to a black.

They were all young ones, waiting for the completion of their second moult before taking to the sea.

A few of the larger chicks had commenced to moult, the change of plumage being observed on the flippers.

Plants do not flower or shed their leaves, nor do birds moult, pair, or breed simultaneously.
