The blue-spotted jawfish (Opistognathus rosenblatti) is a species of jawfish native to the Gulf of California.

Every morning, it rebuilds the burrow entrance.

With the exception of the blue-spotted jawfish O. rosenblatti, [2] Jawfishes are mouthbrooders, meaning their eggs hatch in their mouths, where the newborn fry are protected from predators. The gestation period varies between species. Gold-specs jawfish (Opistognathus randalli) typically keep their clutch of eggs for 8–10 days before hatching.
The yellowhead jawfish (Opistognathus aurifrons) is a species of jawfish native to coral reefs in the Caribbean Sea. It is found at depths of from 3 to 40 metres (9.8 to 131.2 ft). The head and upper body are a light, but brilliant, yellow color slowly fading to a pearlescent blue hue. It can reach a length of 10 centimetres (3.9 in) TL. [2]

Inside the gland cells, blue-green light is produced via the same chemical reaction found in other stomiids, which is then absorbed by a protein that fluoresces in a broad red band. This light is then reflected out through the photophore aperture, where it passes through a brown filter, yielding a far-red light with a maximum absorbance at 708 ...
