01Narrative

Asterina gibbosa is a pentagonal shape with five short arms and a diameter up to 6 cm. The tiny, blunt-armed cushion star ranges in color from greenish-gray, yellowish-green, to reddish-brown. The asteroids are considered a slow moving species with the cushion star being the slowest among all, moving approximately 2.5 cm per minute. The cushion star resembles its given name since the body appears to be inflated like a pillow cushion, emphasizing it small size and blunt arms. The class that the cushion star belongs to, Crinoidea , has retained an upwardly-directed mouth. The cushion star has a body consisting of a tiny central disk to carry the main organs. The mouth of the cushion star is located in the center of the underside. Located on the underside of each arm are grooves that lead to the center that contain hundreds of tube-feet.

05DNA & barcoding8 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 Asterina gibbosa has left across the world's sequence archives.

06Genome at a glanceGoaT

The complete instruction manual Asterina gibbosa carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.

Genome sizehow big the whole instruction manual is

Genome size≈421 386 862 bp assembly estimate

Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).

Sequencing statusassembly quality — how far to trust these numbers

Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

Where the DNA of Asterina gibbosa 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.
