Sea pigs are marine animals around 15 cm long that live about 1,000 metres down on the deep sea floor. They are scotoplanes (sea cucumbers) and their 'legs' are actually elongated feet which are used to push food into their mouths. The apparent antennae on the front of the head are also feet, used to tread the deep sea water. They feed on deep ocean mud and thrive on the organic material present there. The sea pigs are not considered as a threat to humans and they are not an endangered species.
