01Narrative

Anthopleura hermaphroditica, also known as the small brown sea anemone, is a small anemone about 10 mm wide in diameter and very brown in colour. It is native to the waters around Chile and New Zealand. The brownish tinge of its outer surface makes it much harder to distinguish and find unlike some of the other sea anemones. This particular class of anemone can be seen under water as a small brown ring in soft fine sediment and slightly submerged. This brown anemone has quite a high tolerance to changes in salinity and to a high concentration of organic matter in the water.

05DNA & barcoding2 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 Anthopleura hermaphroditica has left across the world's sequence archives.

09Environmental DNA1 detections

Where the DNA of Anthopleura hermaphroditica 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.
