Wild Wednesday – Spiny squat lobster
The spectacular spiny squat lobster, scientific name, Galathea strigose, also known as the spinous squat lobster, lives along the UK coast, with confirmed sightings and records along the seabed and rockpools of the Sussex coast and the English Channel.
Beneath the waves along our coastline lies a world that many of us rarely see but it's just as rich and fascinating as the wildlife on land. One of the more unusual residents of our local shores is this colourful and eye-catching crustacean found around rocky seabeds and reefs.
A hidden coastal character
Despite the name, the spiny squat lobster isn't a true lobster at all. It belongs to a group of crustaceans more closely related to crabs.
With its bright red shell, flashes of blue markings, long antennae and spiny legs, it's hard to miss - if you're lucky enough to spot one. These creatures are usually found tucked among rocks, crevices and seaweed, where they blend into the textures of the seabed.
While they aren't typically visible from the shore, they're a familiar sight for divers exploring reefs and underwater habitats in the English Channel.
Their presence is a great indicator of healthy marine ecosystems, particularly where there is plenty of shelter and food.
What do they eat?
These fascinating creatures are scavengers and opportunistic feeders, dining on small marine animals, dead organic matter, algae and detritus.
They play an important role in keeping the marine environment clean by recycling nutrients on the seabed.
Why are they so hard to spot?
Spiny squat lobsters are:
- nocturnal or crevice-dwelling, often hiding during the day
- experts at camouflage, blending into rocky surroundings
- quick to retreat if disturbed
Even experienced divers can pass them by without noticing.
Did you know?
- spiny squat lobsters have long claws and antennae to sense their surroundings
- they are often found in groups, sheltering together in rocky crevices
- some species can even produce bright colour patterns to communicate or deter predators
Next time you're enjoying a walk along Arun's coastline, remember there's a hidden world just beneath the surface. Creatures like the spiny squat lobster are part of what makes our marine environment so special.
