Keen naturalist Hannah Stitfall is joined by wildlife film researcher Dom Davies to review another programme from the LIVING WORLD archive. The subject today is Spined Loach - a fish you might never heard of because, whilst locally they are abundant, they are classified as a rare protected species and are only found in a handful of places in the UK. Also known as the Spotted Weather Loach because of their ability to detect changes in atmospheric or barometric pressure brought about by changes in the weather, they half bury themselves in fine organic sediment at the bottom of rivers or lakes during the day and then at night sieve the sediment, eating small shrimps and ejecting the mud and sand through their gills. As Hannah and Dom discover, these little fish also have some amazing survival techniques which enable them to survive low oxygen levels, whilst the spines which protrude from under their eyes are thought to help ward off predators.
