About
Twisted or 'Spiral' Wrack is a common 'wrack' seaweed that grows just below the high water mark on rocky shores. Living on the upper shore, it is very tolerant of desiccation and can survive out of the water for long periods, although not as long as Channelled Wrack. It can live for up to four years.
How to identify
Twisted Wrack is a pale olive-brown 'wrack' seaweed, recognised by the spirally twisting fronds with an obvious rib down the middle, and the yellowish, paired swollen tips which are the 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.
