Anchoa hepsetus, commonly known as the broad-striped anchovy, is a species of ray-finned fish in the family Engraulidae. It grows to be about 15 cm (6 in) long. The broad-striped anchovy is found in the west Atlantic along the North American coast from Nova Scotia and the Maine coast scarcely, and abundantly from the Chesapeake bay to the West Indies and Uruguay. It is found most commonly in shoals along coastal waters, as deep as 73 m (40 fathoms) although mostly found water more shallow than this. The broad-striped anchovy spawns in spring. Their eggs are pelagic and hatch within 48 hours at regular spring temperatures. At young ages, it eats copepods, but as the fish ages, its diet begins to consist of other small crustaceans, molluscs, and worm larvae. It is an important food staple for large commercial fishes, such as the American seatrout. It is commonly eaten by birds. It is elongate with large eyes and protuberant snout, large mouth and underslung jaw. Its anal fin is quite short and its front fin lies beneath the end of the dorsal fin. It is grey-green with black dots, but its notable feature is its silvery stripe from head to tail.

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 Anchoa hepsetus 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. 94% of positions are identical in every specimen.
Where individuals differ — all 41 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~3.02 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.

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.
