Though they resemble stingrays, they are generally harmless to humans.
Undulate Ray
Where to find it: Sandy seabeds of the British Isles
They’re often found buried in the sand, so you might not see one unless you’re diving or snorkelling in UK waters.

According to the WildlifeTrusts, undulate rays live on soft seabeds like sand and mud, where they can bury themselves underneath the sediment. Instead of teeth, they have crushing plate,s which help them to feed on their diet of crustaceans.
Although it is commonly called the undulate ray, it is actually a species of skate (sometimes known as the undulate skate). Skates and rays are closely related and look similar, but you can spot the difference by looking at the tail.
Skates have a short tail with small fins and no stinging capabilities, whereas rays have a long whip-like tail.

How to identify
The undulate ray is easily recognisable thanks to the dark wavy pattern on its back. Small spines run down the centre of the animal and along the whole tail.
Did you know?
The undulate skate lays eggs commonly called ‘mermaid’s purses’, which are made of keratin, the same material that makes our hair and nails.
You can find empty egg cases along the shore that have been brought in by the tide.
So the next time you’re walking along a British beach, make sure you keep a wise eye out for this ‘hypnotic’ spectacle!
