01Narrative

Araeosoma thetidis is a species of sea urchin of the family Echinothuriidae. This species can be found in deep sea off Australia and New Zealand. A. thetidis was first scientifically described in 1909 by Hubert Lyman Clark.Kroh, A. (2010). Araeosoma thetidis (Hubert Lyman Clark, 1909). In: Kroh, A. & Mooi, R. (2010) World Echinoidea Database. at the World Register of Marine Species.

05DNA & barcoding7 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 Araeosoma thetidis has left across the world's sequence archives.

09Environmental DNA6 detections

Where the DNA of Araeosoma thetidis 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.
