Gloiopeltis furcata, commonly known as glueweed, jelly moss and fukuro-funori (Japan), is a marine alga that is widely distributed in the North Pacific Ocean, along the shorelines of China, Taiwan, Korea, Japan, and the Pacific shores of Russia; and from the Aleutian Islands south to Baja California. G. furcata has long been utilized as a food source in Asia, where it is also used as a sizing material in silk and other textiles. G. furcata is also a raw material for textile binders. Studies show that extracts of G. furcata inhibit the growth of several human cancer cell lines, and can significantly lower blood glucose levels. G. furcatas thallus is reddish brown to golden yellow, up to 5 cm (2 in) tall. The plant appears black when dry. The cylindrical branches are smooth. The basal crust is perennial, and produces a new crop of branches every year.Gloiopeltis furcata at Seaweeds of Alaska Gloiopeltis furcata inhabits the mid to high intertidal zone of rocky coasts where it grows abundantly, on the tops and sides of rocks and rocky ledges. G. furcata is very similar to Gloiopeltis tenax and Gloiopeltis complanata. The three species are grown, harvested, and often used interchangeably. G. furcata is commercially harvested in China and Japan.Gloiopeltis furcata at Seaweed Industry Association

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 Gloiopeltis furcata has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
Besides the big genome in the nucleus, cells carry a small, circular loop of DNA inside the cell's energy factories — the mitochondria. It is inherited almost only from the mother and is a leftover from ancient bacteria that moved into the cell. The mitochondrial markers above (ND*, COX, CYTB…) are read from exactly this loop. Outer ring = one strand, inner ring = the other.
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.
At a glance
When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard periods (Jurassic, Cretaceous…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. The dashed rules marked ✦ are the five great mass extinctions. 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.

Where the DNA of Gloiopeltis furcata 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.
Signal

How strong is each trace?
Modelled climatemodelled
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.
