Egg wrack is a common wrack seaweed which grows on sheltered rocky shores, around the mid shore zone. It has long, leathery strap-like fronds with egg-shaped air bladders along the lengths. Egg wrack is a long-lived species, with individuals growing slowly for decades. They do not cope well on exposed shores (those with strong wave action), but they flourish on very sheltered shores to the extent of dominating these environments. The dense masses of Egg wrack provide shelter for many species on rocky shores - lift the fronds out of the way and see what is hiding underneath (but make sure you put them back again afterwards!).
