Today’s special animal friend is the Lookdown, Selene vomer, my favorite fish. Native to the western Atlantic and the Gulf of Mexico, the lookdown can live in salt or brackish water. It adapts to a variety of habitats, from Canada to Uruguay, rocky or sandy sea bottoms, in depths up to about 150 feet. Lookdowns are laterally compressed: tall in the vertical plane, very skinny in the horizontal plane. Their scales are shiny silver, sometimes with elegant silver-on-silver stripes.

They are usually less than a foot in length. The record is about 19 inches, and this specimen weighed over 4 lbs. They swim in shoals or schools, maintaining a neat formation and being all reflective. They eat smaller fish, crustaceans, and worms, usually from the bottom. They can make a grunting noise when they are threatened by expelling air from their swim bladder.

Lookdowns are a popular saltwater aquarium fish because they are so hardy and cool-looking. Due to their large size, they require a large aquarium. Only really committed home aquarists keep them, but they are ubiquitous in public aquariums. They can be bred in captivity.

Lookdowns are considered a “game fish.” Sport fishermen enjoy catching them, and you can cook and eat them if you feel you must. The “Catch, Clean, Cook” videos on this are long and hardly seem worth it. Lookdowns are a species of Least Concern.

Just because the ocean is super weird, here’s a Black Sea Nettle, which is a sea nettle that is black, not a nettle found in the Black Sea. These were filmed in the Pacific:

Good morning.

I'm not feeling quite conscious yet, so I'll leave it at that.
