A walk of snails

On days when I don’t feel like getting my hands dirty in the leaf litter, and I’m walking in that direction, I’ve increasingly been turning my attention to one of my local parks, as I find all manner of creatures on the park’s roadside railings (as witnessed by my recent posts: Vapourer cocoon and eggs, 2 January, and Lesser thorn-tipped longhorn beetle, 4 January). Snails are also frequent finds; presumably they don’t mind the exposed conditions and the frequent rain, and I guess they find the surface of the railings easy to slide along. So far, I’ve found four species there …

Oh, and if you’re wondering about the title of this blog, apparently ‘walk’ is the correct, if somewhat ironic collective noun for snails.

Strawberry snail

Though I failed to get a clear photo of the underside of this snail, I’m fairly sure it’s a Strawberry snail (Trochulus striolatus) as it shows the ‘coarse growth ridges running across each whorl’ and had the deep umbilicus typical of this species. It also looked very attractive sitting on the blossom, though it seemed an odd place for a snail to be.

Life on a seepage

On one side of a local railway station there is a huge stone embankment, perhaps 50 feet tall, that was probably constructed in the 1880s (the platforms were opened in 1888). I walked along the path next to this embankment a couple of days ago and couldn’t help but notice several areas where moisture was seeping from between the stone blocks. When I looked more closely at these seepages, I was amazed by how much life they were supporting – an intriguing habitat in miniature.

As well as a variety of mosses and lichens, I found four miniscule springtails, which I think are Monobella grassei, a new species for me, though my identification hasn’t yet been validated.

There was also a stunning little snail, covered in grooves that are actually growth lines. Again, its identity has yet to be confirmed, but I think this is probably a Two-toothed door snail (Clausilia bidentata). The Naturespot website reports that it can often be found hiding in cracks in rocks and that it ’emerges in damp weather and at night and climbs high up on bare surfaces to graze on algae and lichens’, which is exactly what this one was doing.

Tricksy snails

Snails are much more difficult to identify than you might imagine, especially when you don’t – as I didn’t – examine all the relevant parts of the shell that help with identification. The opening of the shell, for example, often holds key features. In this particular case, I was happy just to watch this tiny creature going about its daily life.

And now for something completely different….

I don’t often look at molluscs but these banded beauties caught my eye when I was walking across the Cardiff Bay Barrage earlier this week. I’m fairly sure they’re Cernuella virgata, Striped or Banded snails.

The presence of dark-on-light spiralling bands on their shells is one defining feature, as is their semi-spherical, rather than flat, shape, and the small open umbilicus. And they’re usually found on coastal sites, particularly in calcareous grassland, which fits the Barrage location.

I’ve noticed snails cwtched up together many times in the past but I’d never observed the nitty gritty of what they were actually doing until I saw this pair. Because they’d pulled slightly apart, it was possible to see their ‘apparatus’ in action.

And what about the tiny white spike on the snail at left? Is that one of the love darts that snails stab their mates with? I don’t know enough about snails to be sure but, for more on this point, you can read about the sharp end of snail sex on the National Geographic website here.

At a snail’s pace

I had no intention of sliding down the slippery slope of snail identification but I’ve found a few in recent weeks and couldn’t not try to ID them. And then a friend, who has given up on that ‘too hard’ process, gifted me his guide book. Luckily, there is also a good ‘Slugs and Snails of the British Isles’ group of very helpful folks on Facebook, though you do have to know which bits of the snail to photograph for them to be able to help. So, these little snails are hopefully correctly identified as follows:

170326 snail Aegopinella nitidula

Smooth glass snail (Aegopinella nitidula)
Also known as the Clear glass snail or Waxy glass snail, this little land mollusc can be found munching away on plant matter all year round in gardens and hedgerows, rough grassland, waste ground and woodlands throughout much of Britain. It only grows to around 10mm so is quite little.

170326 snail Discus rotundatus

Rounded snail (Discus rotundatus)
At between 5 and 7mm across, the Rounded or Discus snail (I think that second name suits it very well) is also rather small. Its shell is quite flat but tightly coiled, with up to 6 whorls, and its upper surface is densely ribbed. It’s another very common snail (I obviously haven’t been looking very hard as this was my first sighting) and is especially partial to sheltered damp spots under logs, amongst leaf litter, beneath stones and rubble. Apparently it feeds on detritus (I’m never quite sure what that means!) and fungi.

170326 snail Monacha cantiana (1)

Kentish snail (Monacha cantiana)
It may be named the Kentish snail but this is actually an introduced species. According to the German website Animal Base, it was ‘introduced to Great Britain with farmers in late Roman times and spread mainly in the mediaeval period, occupying a compact area covering S and E England, and still continues spreading (isolated sites in Wales, W central England and Scotland)’. The slight hairiness of my little friend (see photo above right) is because it’s a juvenile – those hairs will rub off as it grows to its full size of around 16mm.
