01Narrative

Aeginura grimaldii is a species of deep sea hydrozoan of the family Aeginidae. It is found in the north-eastern Atlantic Ocean, Pacific Ocean, and the Arctic Ocean. It has a depth range of 660-1200m deep. Live specimens are bright reddish in color, with pale tentacles, and a light red globous capsule dome containing the dark colored red body. It usually measures no more than 4.5cm from the peak of the bell to the end of the tentacles.

05DNA & barcoding6 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 Aeginura grimaldii has left across the world's sequence archives.

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.
