Strawberry-Ness

Strawberry anemone with tentacles retracted

For me rock-pooling transcends age and maturity. I get as much joy and excitement poking under rocks and in crevices as I did as a kid. In contrast I often find sandy beaches boring. Rocky seashores provide opportunities for startling discoveries and a glimpse into life under water. There was the time I came across a dogfish trapped in a rock pool and another when I first discovered blue-rayed limpets adorning kelp like miniature landing strips for alien sea craft.

Last week I was indulging in such activity at Ness beach near Shaldon, a hidden treasure only accessible by an original smugglers tunnel cut through the cliff (Smuggler’s Britain, 2013). The red cliffs enclose a mainly shingle beach, but at either end are large areas of rocky seashore. It was amongst these rocks that I found a real treasure clinging limply – A Strawberry anemone (Actinia fragacea), a large relative of the commoner Beadlet anemone (Actinia equina). These fruity creatures, strawberry red flecked with pip like greeny-yellow spots, can grow up to 10cm long (excluding tentacles). These are primitive carnivorous animals using stinging cells in their tentacles to capture prey (including small fish) that then pass the food into a simple stomach (Oakley, 2010).

Like its namesake this anemone enjoys a warm climate, being a southern species  present in the Channel as far east as Brighton, but is expected to respond to climate change in UK waters (Kendall, et al., 2004) – it otherwise commonly occurs in Mediterranean and West Africa. So as global temperatures rise we are likely to see more of these gems smuggling onto our rocky shores - happy hunting.

Windless anemones

Over the last few weeks our local Devon woodlands have sprung to life with the white starlight flowers of Wood Anemone (Anemone nemorosa), carpeting the open floors. I’ve also recently been to the beach a couple of times and I have become curious about the marine namesakes, such as the Snakelocks Anemone (Anemonia viridis) pictured above. What is the commonality of the name, ‘anemone’?

Looking up in the dictionary, 'Anemo’ is Greek for wind, which I could have guessed from knowing that an anemometer is an instrument to measure wind. The Shorter Oxford Dictionary (1952) defines ‘Anemone’ as “daughter of the wind” and the Wood Anemone as “the wind-flower”. Other sources state that the wind God, 'Anemos' sent Anemones early to herald his early coming in spring - the Wood Anemone is certainly one of our earliest flowering plants. However there does not seem to be any evidence that wind plays much of a part in the life history of this plant. They spread mainly via underground rhizomes as long-lived clonal groups, and pollination is via insects (Stehlik and Holderegger, 2000). An alternative name is ‘Smell Fox”, which is explained by the musky smell of the leaves (Woodlands.co.uk, 2012) – a bit a blunt and ‘to the point’ of a name, but at least more descriptively accurate.

The link with sea anemones seems more straightforward – these sea creatures resemble flowers with their brightly coloured spreading tentacles – hence the Strawberry Anemone (Actinia fragacea) which is reddish with flecks like pips on a strawberry. Indeed, until modern times many believed that sea anemones were actually plant species. However the resemblance of the large variety of sea anemones does not seem particularly reminiscent of plant anemone species – many look more like colourful sunflowers or daisies.

So, in pedantic summary the anemones don’t have much in common with wind, and sea anemones don’t look any more like anemones than many other flower genera. This should not however stop us admiring the wonderful beauty of anemones, plant or animal.
