Janolus capensis, the Cape silvertip nudibranch,Gosliner, T.M. (1981). "The south African Janolidae (Mollusca, Nudibranchia) with the description of a new genus and two new species". Annals of the South African Museum, 86(1): 1-42. is a beautiful species of nudibranch, or sea slug. It is a marine gastropod mollusc in the family Proctonotidae. Apart from striking differences in the egg ribbons, individuals of this species are externally not distinguishable from the medallion silvertip nudibranch.

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 Antiopella capensis has left across the world's sequence archives.

09Environmental DNA9 detections
Where the DNA of Antiopella capensis 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.
