Recorded distribution in Britain and IrelandBifurcaria bifurcata is a southern species found on the Atlantic coast of France, Spain and Portugal and extending to the south and west coasts of England and the west coast of Ireland where it is sometimes common. It is absent from Scotland.
HabitatBifurcaria bifurcata is usually found in rock pools on the middle and lower shore, particularly on exposed beaches. It also forms a low water zone in some locations in south-west England and west Ireland.
- Sterile tips to fronds are rounded and slightly enlarged.
- Air bladders, if present, are small.
- Unlike the other fucoids, Bifurcaria bifurcata has no disc-like holdfast.
Bifurcaria bifurcata is perennial and hermaphroditic.
