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.

Hairy snail, slime mould, slugs, springtail, under a log

When wet weather forces a change of plan, sometimes the only thing for it is to head to the woods and turn over some logs, because there’s never nothing to see under a log!

Two slugs, possibly even the same species despite their obvious colour differences.

Eggs? Those on the left might well be slug or snail eggs but the ones on the right were much smaller and seemed caught up in a web or perhaps just strands of slime. I didn’t poke them – didn’t want to disturb them – so I’m not sure of their texture.

200116 5 slime

A slime mould, though not as much slime as I was hoping for. Possibly one of the Trichia species, perhaps Trichia persimilis.

200116 8 springtail

A springtail, probably one of the Entomobrya species but I really needed a photo of its upper side to be able to confirm its identification.

200116 7 hairy snails

Hairy snails (Trochulus hispidus), I believe, as the only other hairy snail has a more conical shell. It always seems odd to me for a snail to have hairs … but odd is good, interesting, never boring!

When the rain finally abated mid afternoon, I went to vote and then headed down to the seaside, to clear my head with some fresh air. The tide was out so I couldn’t resist having a brief fossick along the beach. It’s a stony shore and there are never many shells to be found but I did find a few nestled amongst the stones.

Wales is once again living up to its reputation for being a wet country, a fact about which I may not be particularly happy but the slugs are once again / still loving it.

191018 Black slug (1)

I know Wales has a reputation for being a wet country but the past couple of weeks have been much wetter than any I’ve known in my four years here. Still, it’s good weather for slugs, which is why this large and colourful beastie was to be found sliding its way across my path today. It was about 3 inches long and I presume, despite its colour – they vary a lot, that it’s a Black slug (Arion ater agg.), a species that can only be positively identified by examination of its genitals. I’m not going there!

#365DaysWild, beach fossick, beachcombing, fossilised seashell, fossils, Penarth Head, seashell

As part of this morning’s local meander, I went for a beachcomb at the base of the cliffs at Penarth Head – not too close to those cliffs as they’re continually shedding small stones and occasional larger boulders but it’s safe enough nearer the water’s edge when the tide’s going out. I didn’t linger long as people arrived to run their dogs, sending sand and stones everywhere. However, I did find this little beauty before they arrived – a fossilised seashell I think.

p.s. My fab Facebook friend Mark says that the only ‘Jurassic bivalve with that pattern in my books is something called Oxytoma inequivalvis’, so now we have a name. Thanks, Mark.

The weather was back to grey and drizzly again today so I donned my wet weather gear and headed to Cogan Wood to spend part of day 5 of my #7DaysofWildChristmas challenge turning over a few rotten logs and branches. And what did I find lurking there?

Woodlice; snails both long and rotund; earthworms; luscious balls of orange slime; tiny globular balls that looked like the eggs of something or other; pale little lumps of White or Crystal brain fungi; slugs brown and black; a stripey legged Harvestman; miniscule white mushrooms adorned with drops of water; a young centipede or millipede – I can never be quite sure which is which; dark little cup fungi, black with olive rims (Catinella olivacea) – very pleased with that find; and various other things, the photographs of which were either out of focus or too grainy due to the poor light conditions in the woodland. There’s nothing quite like getting wild and muddy – it was fun!

Aliens at the seaside

barnacle, barnacle as aliens, beachcombing, finds at the seaside

During a bimble along my local beach on Thursday, I found these little molluscs clinging on for dear life to a piece of seaweed. Initially, I assumed they were some kind of barnacle, but then I looked closer.

And saw their ‘faces’!

I wonder if this is where the idea for the movie Aliens came from?

170702 Square-bashing SS9073 (1)

A few days ago I posted about my square-bashing adventure near Llanbeder, in Gwent. Hilary and I have now also square-bashed another under-biodiversity-recorded 1-km square, this time near St Brides Major in Glamorgan.

170702 Square-bashing SS9073 (2)

As the seagull flies we were within a kilometre of the sea and the geological substrate was very different, so the habitats we surveyed were more diverse. One public path led us down a heavily wooded driveway to an old house, another ran between the edge of that same woodland and fields sown with cereal crops (and there the hogweed was flowering which greatly improved my insect tally), and the third took us over paddocks of rough unimproved grassland, with patches of low rushes, all bordered by a wild old hedgerow.

Interestingly, this time Hilary’s plant list was about 20% lower than that from our previous square (though she still had around 80 species), whereas my list of everything else was about the same percentage higher (at around 100 species of insects, fungi and lichens, molluscs, etc).
