01Narrative
The southern thorny skate (Amblyraja doellojuradoi) is a species of fish in the family Rajidae. It lives off the coast of Argentina and Uruguay (the southern tip of South America), and around the Falkland Islands in depths ranging from 51 to 642 m. Its maximum size is 69 cm. It lays oblong egg capsules with horn-like projections at the corners which are laid in sandy or muddy flats. The eggs measure 86.4 mm in length and 56.2 mm in width.

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 Amblyraja doellojuradoi has left across the world's sequence archives.

▸ drag or hover over the strip to read any position — letter and how much it varies
Violet ticks below the strip = positions where individuals differ; flat = the species' unchanging signature. 100% of positions are identical in every specimen.
Where individuals differ — all 3 variable positions, in barcode order
Each circle is a barcode variant; bigger = more specimens, colour = region. Lines join the most similar variants and the tick marks count the mutations between them — a tight cluster is one “dialect”, a long line a more divergent lineage. Click a circle to list its actual specimens.

Closest relatives by DNA barcode
The species whose COI barcode is most similar to this one — a quick “who is this most like”. The percentage is how much the barcode differs; it approximates, but is not, the full evolutionary tree.
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
