The Glasshead Barreleye (Rhynchohyalus natalensis) has "bidirectional eyes” and can see images using their two, primary eyes. Using a curved, mirror-like lens and retna below each primary eye, they can also see bioluminescence below them. Gulf of Mexico, 2017

Today's fish is the Scaleless Dragonfish (Bathophilus nigerrimus)! They have a fearsome mouth, but their jaws are very weak, and they rely on skewering prey with their fangs.

Today's fish is the Giant Sea Bass (Stereolepis gigas)! These giants are apex predators of the kelp forest, reaching a reported 562lbs, and living 75yrs! Like many other big fish, they're endangered, and there's currently a population of 500 in CA.

Glaucus atlanticus, the blue sea dragon, drifts on the ocean’s currents, floating upside down at the surface, which provides camouflage from flying and swimming predators.
It preys almost exclusively on the venomous Portuguese man-of-war, which it can eat without being harmed. – at Nevada, USA

This is the 23rd known specimen of the "Deceitful Dreamer" (Lophodolos indicus). The name, according to fishbase, comes from "describing a deceitful little fish that beguiles its prey with a baited illicium." The inset to the lower right is a close up of the esca or "lure."

There are about 3,000 known species of nudibranchs, but some scientists think we’ve only discovered about half the earth’s population. Nudibranchs live in almost all areas of the ocean—most being benthic, traveling on or near the sea floor. – at Nevada, USA

Viperfish (Chauliodus sp.) are deep water predators. The teeth of these fishes pierce and hold prey. The teeth are so enormous that the largest of them don’t fit into their mouths.

Fun Fact Friday: The Pacific spiny lumpsucker, Eumicrotremus orbis, has fused pelvic fins that form a suction cup. This allows them to attach to algae and cling on to objects in fast moving water. They also might be the cutest fish ever! 1/2
