Brosmophycis
The Red brotula is a species of viviparous brotula found along the North American Pacific coast from Alaska to Baja California. This fish is often displayed in public aquariums. This species grows to a length of 46 centimetres (18 in) TL. The red brotula is the only known member of its genus.
No picture of Brosmophycis was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Brosmophycis, or no answer at all. This entry cannot say which.

Time the record covers
At least 47 million years on record.
The record covers at least 48.07 Mya to 774 ka. No occurrence read is dated outside 56 Mya to 129 ka.
33 occurrences of Brosmophycis on record, most of them in the Oligocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
33 occurrences- Eocene27%
- Oligocene46%
- Miocene12%
- Pliocene9%
- Pleistocene6%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 30 sites for Brosmophycis, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 33 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
