Slug sperm!
@markwill93 is studying whether invasive species of Arion slugs have longer sperm than their native relatives, using our SEM. If so, they're more likely to ‘win’ during competition with native slugs, causing rapid genetic dilution of native slug species #microscopy

@SchwanckTanja @UoABioSci @TheFSBI @saveourseas @nature_scot @marinescotland @GenSocUK Well done Tanja! I like how this comes under the topic of 'Skateboarding' on twitter 😂

Read my new article published in Science Direct, which explains the issues surrounding invasive large arionid slugs and gives the background for much of my PhD project. #Slug #Science https://t.co/F4qdyXhZvz

More baby slugs. This time Limax cinereoniger. #Slug #Invertebrate

@fonthintrelpine Yes! Those ones exactly. You can buy them as finely ground or just grind them up yourself with a motar and pestle. It is much easier for the slug to ingest when they are well ground. I normally dust a thin layer on the lid of their enclosures.

Often misidentified as Arion rufus or Arion ater, this is actually the Spanish slug Arion vulgaris, one of the top 100 worst invasive species in Europe. #Slugs #Molluscs #InverteFest #Scotland

My colleague @SoilandGas is doing a twexperiment for a talk on #SciComm for our department @UoABioSci later this week 😊! Please give him a second of your time and show him how far tweets reach if you can! 😁 (🏴󠁧󠁢󠁳󠁣󠁴󠁿 + 🏴󠁧󠁢󠁥󠁮󠁧󠁿 depending on my mood 😉)

The 'Spanish stealth slug', Arion flagellus, mid copulation. First reported in Spain in the 1800s, these highly fecund hermaphroditic slugs have become a common occurrence throughout the UK. Their arrival threatens the persistence of native slug species. #Slug #Mollusc #Arion
