01Narrative

Apterichtus flavicaudus, variously known as the orange snake eel, sharpnose sand eel or sharpnose snake eel, is a species of snake eel native to the Indian Ocean from the Seychelles to Hawaii in the Pacific Ocean. It can be found at depths of from 7 to being particularly common in shallow coastal waters with sandy substrates in near vicinity to reefs. This species can reach a length of 80 cm TL.

05DNA & barcoding1 specimens

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 Apterichtus flavicaudus has left across the world's sequence archives.

Where the DNA of Apterichtus flavicaudus 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.
