01Narrative

Amphiduros fuscescens is een borstelworm uit de familie Hesionidae. Het lichaam van de worm bestaat uit een kop, een cilindrisch, gesegmenteerd lichaam en een staartstukje. De kop bestaat uit een prostomium en een peristomium en draagt gepaarde aanhangsels. Amphiduros fuscescens werd in 1875 voor het eerst wetenschappelijk beschreven door Marenzeller.

05DNA & barcoding9 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 Amphiduros fuscescens has left across the world's sequence archives.

09Environmental DNA7 detections

Where the DNA of Amphiduros fuscescens 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.
