Co-occurrence patterns of introduced terrestrial flatworms in metropolitan France revealed by citizen science - Biological Invasions Terrestrial flatworms are a group of successful carnivorous invaders that have been introduced to many regions outside their native range. In France, six different species have been recorded in significant numbers over the past 20 years, with a recent increase in observations. These include predators of earthworms, gastropods and soil arthropods. Their presence raises concerns about their potential to disturb communities of soil-dwelling organisms. Here, we aimed to describe patterns of co-occurrence between these species in France, using a national inventory of alien flatworms coupled with estimates of potential co-occurrence derived from ecological niche models trained at the global scale. We showed that, although alien predatory flatworms are relatively widespread in France, they co-occur less frequently than expected simply based on each species’ respective environmental suitability, i.e., they tend to be found alone and not in association with other alien flatworm species. However, ecological niche models indicate a high potential for more frequent co-occurrences in the future. We hypothesize that their limited dispersal ability and their relatively recent introduction has confined most species close to their introduction sites. However, if they eventually fill out their potential range, predators of different taxonomic groups will co-occur more frequently, leading to greater predation pressure in invaded ecosystems. Our conclusions shed light on the current and future co-occurrence patterns of alien predatory flatworms in France. Understanding how they translate in the field in terms of predation and competitive interactions will be crucial for predicting the impact of flatworm invasion on soil ecosystems.

All has already been said. It's just a closeup of the head, also against a black background, but I did a poor job at cleaning the glass.

Here's a closeup of the head with those flappy things and all the little eyes. If you know what the flaps are called and what function they serve, please let me know! :D

If you must call something slimy, let it be this, not frogs. Hammerhead worms, possibly invasive, absolutely lethal to earthworms, and they have no natural predators in the country.

A glossy black fat tubular Flatworm with a pair of longitudinal grey stripes on its back, and a pointed 'head end' that has tiny eye spots along its sides

A beautiful Parakontikia ventrolineata found in the garden, one of two species of Flatworm found this weekend.

Examples of characteristic traces or structures attributed to representatives of Platyhelminthes which can be preserved in the fossil record. (A) Modern marine polyclad producing a mucociliary trail (drawing based on Collins et al. 2000); (B) Modern planarian producing a mucociliary trail (drawing based on Pantin 1950); (C) Circlet of hooks attributed to monopisthocotylean neodermatans associated with Devonian gnathostome fish (drawing based on Upeniece 2001); (D-F) Igloo-shaped concretions attributed to gymnophallid trematodes in a fossil bivalve (drawing based on Rogers et al. 2018) and a modern bivalve (drawing based on Ituarte et al. 2005); (G, H) eggs attributed to eucestode neodermatans in a Permian coprolite (drawings based on Dentzien-Dias et al. 2013). Scale bars: A = 5.0 mm, D = 0.5 mm, G = 1.0 mm, H = 50 μm.

Stratigraphic occurrence of fossil evidence for particular orders of Platyhelminthes. Phylogeny follows Littlewood and Waeschenbach (2015) with the exception of Neodermata which follows Brabec et al. (2023). See Table 1 and text for further details of each find.

Kontikia ventrolineata - our handsome garden Flatworm showing its ventral stripe, and its row of eye spots all along the body. Love these little shapeshifting aliens.
