01Narrative

Holopneustes inflatus, the pink sea urchin or sea grass sea urchin is a species of sea urchin of the family Temnopleuridae. Pink Sea Urchins are found in southern Australia, in New South Wales, Victoria, South Australia, Western Australia and Tasmania. The habitat is inter-tidal rocky areas and coastal waters up to a depth of 75 metres. Often seen amongst kelp. A small and delicate urchin, food is a variety of plants and dead animals. The test diameter is up to 5 centimetres, usually brightly coloured and finely tuberculated. Spines are less than 5 millimetres long. Spines may be orange, dark red, pink or yellowish.

05DNA & barcoding1 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 Holopneustes inflatus has left across the world's sequence archives.

09Environmental DNA9 detections

Where the DNA of Holopneustes inflatus 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.
