My hobby is fishing. Carassius cuvieri, originally native to Lake Biwa, has been introduced across Japan for recreational fishing. Despite being a domestic invasive species, it has a surprisingly charming face. #Fishing #FreshwaterFish #FishPhotography #Nature #Biodiversity #Japan #InvasiveSpecies

That’s an interesting idea! I know flies don’t usually prey on land snails, so perhaps you mean a kind of parasitic relationship? I’ve never actually seen flies attacking snails in the field, but defense against other animals could be possible.

Mollusc_Lab @naturaearchive.bsky.social · 07/10/2025

That’s great to hear! Michael Shea’s work is fantastic — I’d love to see him join Bluesky too. I also study the evolution and taxonomy of land snails, but there are still so many mysteries to uncover.

110

Mollusc_Lab @naturaearchive.bsky.social · 06/10/2025

Absolutely! Hairs can really enhance concealment — your backyard examples make a lot of sense.

110

Mollusc_Lab @naturaearchive.bsky.social · 06/10/2025

That’s an excellent point — camouflage seems quite plausible, especially considering visually oriented predators like Pitta. The possibility that debris could adhere to the bristles and enhance concealment is fascinating.

210

Mollusc_Lab @naturaearchive.bsky.social · 06/10/2025

That makes sense. Some Aegista species actually have hair-like structures on their shells, so dew collection might be a possible function. I’ve also wondered whether it could help with camouflage or microclimate regulation on the shell surface.

120

Mollusc_Lab @naturaearchive.bsky.social · 06/10/2025

Thank you for your interest. The function of the bristles remains unknown. If anyone knows more, I’d love to hear your thoughts — even hypotheses are welcome. Personally, I suspect it may relate to humidity or predator defense, but there’s no clear evidence yet.

Although minute in size, they represent remarkable taxonomic and ecological diversity. Some species are widespread, while others may be highly localized or even undescribed. For malacologists, such micro-snails offer valuable insight into biodiversity, biogeography, and conservation.
