The addition of nutrients may encourage the growth of ephemeral and epiphytic algae and therefore increase the food available to sea-urchin populations. It was the object of a specific fishery in Cornwall in the 1980s. Adults can repair non-lethal damage to the test and spines can be re-grown but most dredge impact is likely to be lethal. Isle of Wight Local Records Centre, 2017. The genus Echinus is derived from the Greek 'echinos' meaning 'a hedgehog'. The test may be relatively flat in shallow water but taller in deep water. Hyman, L.V., 1955. Echinoids move away from bright light and seek out crevices and / or cover themselves with debris such as shells and drift algae, the 'covering reaction' (see Boolootian (1966) for discussion).
