01Narrative

Cavernularia obesa is a species of marine cnidarians in the family Veretillidae. Cavernularia obesa is widespread throughout the tropical waters of the Indo-Pacific area. It is a bioluminescent organism whose light-emitter is composed of 2-(p-hydroxyphenylacetamido)-3-benzyl-5-(p-hydroxyphenyl)pyrazine.The light-emitter in bioluminescence of the sea cactus Cavernularia obesa. Osamu Shimomura, Shoji Inoue and Toshio Goto, Chemistry Letters, Vol. 4 (1975) No. 3, pages 247-248

05DNA & barcoding3 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 Cavernularia obesa has left across the world's sequence archives.

06Genome at a glanceGoaT · NCBI

The complete instruction manual Cavernularia obesa 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≈436 256 191 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.

09Environmental DNA1 detections

Where the DNA of Cavernularia obesa 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
