Aplexa hypnorum, or by the common name, the moss bladder snail, is a species of small air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Physidae, a family which are sometimes known as the bladder snails. As is true of all physids, the shell is sinistral, or left-handed. The species inhabits temporary water bodies and occurs in the Eurosiberian Boreo-temperate or possibly the Eurasian Boreo-temperate if East Siberia specimens are correctly identified. It may be Holarctic, again if North American specimens are correctly identified. Aplexa hypnorum shell and live animal, as shown by Henry Adams and Arthur Adams, 1858, as Bulinus hypnorum, a synonym.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Aplexa hypnorum has left across the world's sequence archives.

Where the DNA of Aplexa hypnorum was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
