Anemone is the largest of the common sea anemones
found around the British Isles inhabitating the shallow seas all around
the coast and occasionally found on rocky shores during the colder months
of the year. Despite its large size and spectacular colours it is often
overlooked between the tides, its tentacles covered
in gravel. It is an Arctic species intolerant of
temperatures in excess of 22°C.

Hamblett, you can imagine how a crab could blunder into the sea anemone
and be eaten.

Diet includes crab, mussels.
diet of the Dahlia Anemone
is known to include large crabs and mussels in
their shells. The mussels are smashed off the rocks by the waves and fall
down into rock gullies where these anemones may congregate. Its method
of feeding on crabs is unclear. I am still unsure whether the crabs blunder
into the tentacles and get swallowed up dead or alive. Aquarium
study sheds no further light on the capture. One spider crab species the
observed to live amongst the blunt tentacles of this sea
anemone for over a year before being swallowed up over night.
Worldwide, Arctic and temperate, below 22° C.
