01Narrative

Neverita duplicata, common name the shark eye, is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails. In 2006, a paper was published which made it clear that a second, very similar, species with a smaller range of distribution also lives in part of the range inhabited by Neverita duplicata. The second species had previously been considered to be simply a form of N. duplicata, but it is now recognized as Neverita delessertiana.Huelsken, T. et al. (2006) Neverita delessertiana (Recluz in Chenu, 1843): a naticid species (Gastropoda: Caenogastropoda) distinct from Neverita duplicata (Say, 1822) based on molecular data, morphological characters, and geographical distribution. Zootaxa, 1-25. PDF.

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 Neverita duplicata has left across the world's sequence archives.

09Environmental DNA5 detections

Where the DNA of Neverita duplicata 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
