About
A very common seaweed, Channelled Wrack grows around the high water mark on sheltered, rocky shores. Living on the upper shore, it is very tolerant of desiccation and can survive for up to eight days out of the water. In fact, if it is fully submerged for too long, it may die. Channelled Wrack can live for up to four years.
How to identify
A smallish brown 'wrack' seaweed, Channelled Wrack can be recognised by the obvious 'channels' that its frond form - produced by their sides being rolled in. Lighter-coloured, bumpy, v-shaped swellings at the ends of the fronds are its reproductive structures.
Where to find it
Common on rocky shores all around our coasts.

How can people help
Seaweeds provide a vital link in the food chain for many of our rarer species. Our seas and coastline are in need of protection if we are to keep our marine wildlife healthy. The Wildlife Trusts are working with fishermen, researchers, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives. This work has recently had a massive boost with the passing of the Marine Bill, promising sustainable development of the UK's marine environment. Do your bit for our Living Seas by supporting your local Wildlife Trust.
