The Pelican´s foot shell is usually found dug down a few centimetres in the bottom sediment. Here, the large outer lip acts as a protective covering for the cavity that the shell has dug for itself with its long and thin foot. On each side of the outer lip, the shell has bored a canal up to the sediment surface to enable ventilation of its cavity. Through these canals the shell is also able to stick out its trunk to get food which is composed of decomposed plant material and microalgae. |
