The bloody henry is a species of starfish found around most of the UK. It can be a bright reddish, orange or yellow in colour. It grows to around 10cm across, with a small number being up to half as large again. They have five slender arms and an extremely rough texture. The bloody henry is very common around much of the British Isles. It does not tend to be found in the inter-tidal zone and instead lives slightly further out to sea in deeper water. Their feed on plankton and other microscopic sea creatures.
Technically, there are actually two separate species (see scientific names above), but they are so similar – laboratory tests are needed to verify the differences – that they are almost always classed as a single species.
