The bandtooth conger (Ariosoma balearicum), also known as the Baleares conger or the Balearic conger,Common names for Ariosoma balaericum at www.fishbase.org. is an eel in the family Congridae (conger/garden eels).Ariosoma balearicum at www.fishbase.org. It was described by François Étienne Delaroche in 1809, originally under the genus Muraena.Delaroche, F. E., 1809 [ref. 17380] Suite du mémoire sur les espèces de poissons observées à Iviça. Observations sur quelques-uns des poissons indiqués dans le précédent tableau et descriptions des espèces nouvelles ou peu connues. Annales du Muséum d'Histoire Naturelle, Paris v. 13: 313-361, Pls. 20-25. It is a subtropical, marine eel which is known from the western and eastern Atlantic and the western Indian Ocean, including North Carolina, USA; the northern Gulf of Mexico, northern South America, Canada, Portugal, Angola, the Mediterranean, and the Red Sea. It inhabits reefs and littoral shelves, and burrows into sand and mud. It dwells at a depth range of 1–732 meters, but most frequently between 20–100 m. Males can reach a maximum total length of 35 cm, but more commonly reach a TL of 25 cm The bandtooth conger is of minor interest to fisheries.

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 Ariosoma balearicum 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. 96% of positions are identical in every specimen.
Where individuals differ — all 27 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.

07Deep time~24.2 Ma lineage
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin24.2 Ma TimeTree
When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

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.
