[Note Guidelines] Photographer's Note
The Beadlet Anemone, Actinia equina, is a very common sea anemone, abundant on intertidal rocky shores in Europe. The species can tolerate exposed and sheltered situations. In this case, the coast is very exposed, where the North Sea and byfjorden (the city fjord) meet

On the 22th July, the wind was moderate with an incoming tide. The shallow sloping rocky shore on Tungenes, with differential erosion and relatively minimal tidal movement, creates many small crevasses, ideal for sea anemones, barnacles, whelks and seaweeds such as Enteromorpha linza and Corallina (shown here) etc.

The tentacles of anemones contain stinging organs called cnida of which the nematocysts are the most important. The tentacles will extend in an active search for small prey, plankton, organic remains etc. The nematocyets are capable of firing a poisoned barb to paralyse small organisms. The food is then dispatched down the tubular gullet, the opening can be seen here, and any remains will be expelled through the 'mouth'.

According to Wikipedia the anemone displays 192 tentacles, arranged in six circles. I didn't count them!

The colours that I noticed were orange, deep red and a pale brown, which may be different species.

Hello Amelia,
WOW !.... this is not common in TN! ... see anemones in natural state, directly photographed on the rocky shores of northern sea! ... an exotic picture of you hand to TN! ... good job!
The coloration is overwhelming, ligths and textures are very well recorded, and the diversity of elements produces enough visual interest. I like the fact that the water surface canbe viewed, and the snail outside. Good job, really innovative and interesting.
TFS, Regards, Jesús

Hello Amelia,
For me as not living close to the sea this colorful Anemone looks quite exotic and very interesting. Sharpness is good and the colors seem natural. The composition could eventually be improved. I didn't know that there is a precise number of tentacles! I wouldn't count either :-)
Have a nice evening

Hej Amalia,
Another lovely shoreline photo that I've overlooked! Having grown up in Stockholm I miss the rocks as down here in the south there are only long sandy beaches (with lots and lots of people at the moment)! These Anemonies are so beautiful and very well captured! Fabulous colours and well composed too!
Many thanks and cheers, Ulla

Halloo Amelia,
First of all a belated welcome to TrekNature. I hope you will enjoy this site as much as I do and post many, many photos. Judging from your portfolio so far, you do not need to worry about competing with other members: your photos are truly GREAT!

In any case, as a member wrote not long ago: this is not a photo saloon competition but learning about nature - and to start with - this image is truly a revelation!

I never realised - having seen coral reefs in the Indian Ocean - that in the north (cold sea) the sea life is so colourful.

The colours are absolutely stunning and the photo so rich in sharp details, and I add your work to my favorites.

How deep (shallow) was the water approximately? I am amazed, that the waves/tide did not obscure the shore life!

Have a nice evening
Warm Greetings from South Africa
Ingrid
