green on a red column) spots all over the column of this anemone. The similar
species Actinia equina can have green stripes and dotted lines,
so there can be confusion between the species as the dividing line is not
clearly demarked by appearance.

pale tentacles which is frequently seen in wild specimens. It has a reddish-brown
column with a full array of green spots.

Anemone, Actinia equina,
collected on Worthing Beach
on 18 April 2011 and
recorded immediately below,
now developed into an immediately recognisable as a "strawberry
type" Actinia fragacea, but not a bright
crimson as a "classic"
specimen: the column is dark brown spotted with small green spots, the
tentacles were now a light crimson.
large plain green specimen of the Beadlet
Anemone, Actinia equina,
collected on Worthing Beach
on 18 April 2011 suddenly
diminished in a manner seen before in the Actinia
anemones. The green specimen with a basal diameter of approximately
60 mm and a larger tentacle span shrivelled up into a smaller version that
looked as though it might be dying, and the tentacles became thinner than
those of the Snakelocks Anemones, Anemonia
viridis, and the oral disc disappeared
from view covered by the partially retracted tentacles. On 20
May 2011, I noted that sea anemone had returned
to its normal appearance. On 21 May 2011 I
noticed that its column was covered in spots which were pronounced enough
to be nearer in appearance to the designated species Actinia
fragacea. Its spots were distinct light
green but the background colour of the column became brown rather than
red. It was slightly smaller with a basal diameter of about 50 mm. Intermediate
forms or Actinia
green lines and spots are known to occur occasionally. This anemone has
tentacles whereas the usual "strawberry
type" has crimson or red tentacles

late February 2003 I was fortunate enough, and rather pleasantly surprised,
to find a rather large strawberry anemone (a green variant of around
10 cm crown diameter) underneath a relatively small, unanchored flat piece
of rock, at the mid-tide level of the shore near Rock-a-Nore Road, Hastings.
I removed the anemone and placed it in my marine aquarium following an
overnight period of thermal acclimation to its new surroundings (warming-up
rate of around 1 degree C per hour) to room temperature with aeration in
a bucket. Since then the anemone has settled in well to aquarium life.
15 April 2003, one day following a complete change of the water in the
tank, the above strawberry anemone started spewing out beige-coloured lumps
and strings of particulate material from its "mouth" which quickly broke
up and was dispersed by the water flow circulating in the tank. I siphoned
off some of this material for closer examination with a x10 hand lens
which revealed what looked like white/beige-coloured eggs - perfectly uniform
and spherical in shape. After 3 hours of ejecting this material the
water in the 60 x 30 x 30 cm tank had turned a cloudy milky colour. Within
24 hours it started to smell (the type of smell you get if you leave an
unaerated bucket of natural seawater for a day or two) and within 48 hours
I had to carry out a complete change of the aquarium water.
the above event the strawberry shrunk temporarily in size. Now the 18 April
(3 days later), the above strawberry seems to have regained its former
size, following refeeding, and seems to be fit and well.

I collected 6 Strawberry
Anemones today at Falmouth Gyllingvase Beach, Cornwall. They are
prolific at mid-low water mark but only on the one set of rocks on the
north/west side of the beach, they do not appear at all on the rocks on
the opposite side. Simon
found very healthy specimens at Freshwater Bay on the Isle off Wight (butI
could find them nowhere else on the island) in 1997
found a small number at Carlion Bay, St Austell, Cornwall in September
of them was the smallest that I have ever seen, with a base of well under
1 cm. It looked plump and healthy, and was in a rock crevice with
a large specimen, so I assumed it to be young.
kept a specimen of the "strawberry" Beadlet
Actinia fragacea from
the NE Atlantic Ocean that lived for 10 years (without showing any sign
of reproducing) and it may have lived much longer. I got the specimens
muddled up when transferring them to another tank.

Anemone that appears to be developing the strawberry pattern when it
was previously all brown. This is my first observation of this in over
