01Narrative

Holothuria (Semperothuria) cinerascens is a species of sea cucumber in the family Holothuriidae. The sea cucumber is widely distributed in the Pacific and Indian oceans, being found from the Red Sea to Madagascar and from Japan to Australia. It was first described by Brandt in 1835.

05DNA & barcoding14 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 Holothuria cinerascens has left across the world's sequence archives.

Variant network

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.

Where the DNA of Holothuria cinerascens 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.
