DAHLIA ANEMONE

Scientific name: Urticina felina

What to look for:

Colouring and appearance: Variable in colour, between grey-white to blues and greens to magenta, and sometimes oranges and yellows. Up to 150+ tentacles and with a debris-covered warty column.
Size: Up to 10 to 15 cm across
Where: Lower shore and sublittoral zone 

Dahlia AnemoneOccasionally you may be lucky enough to find a rock pool full of this pretty, if rather squat anemone, but more usually you will find it nestled singly beneath seaweed and other debris. You can tell it apart from similar anemones by the banded pattern of markings on the tentacles. They live on a diet of small fish and crustaceans, which they capture and immobilise using the stinging cells in their tentacles.

Did you know...?

...The column (verruca) is usually covered in bits of seashells and stones, making this anemone look something like a small mound of gravel when the tentacles are retracted.
