If you’ve ever seen spaghetti like mounds on the beach, those are a sign of lugworms. The worms themselves are very rarely seen in real life, but the signs that they are there are common!
Behaviour
Lugworms live in burrows in the sand both on the beach and in the sandy seabed. Their burrows are u-shaped and are formed by the lugworm swallowing sand and then excreting it out the other end, creating those spaghetti like piles of sand you may see along the shoreline, which are known as casts.
Size
12-20 cm in length.
Status
Common.
Distribution
All around Scotland’s shorelines.
