Today’s special animal friend is the longnose gar, Lepisosteus osseus. These big, cool fish are found in fresh and brackish water habitats throughout the eastern and midwestern United States, through Texas and up into New Mexico, where they live in the Pecos River and its tributaries. Longnose gar are often described as “primitive fish,” which is quite a slur, in my opinion, or “prehistoric” fish, which is just dumb. They have a spiral valve intestine, which does what an intestine should – digestion – and a highly vascularized swim bladder that allows them to breathe from the water and from the atmosphere. Hah.

Longnose gar eat other fish. They are ambush predators, hovering in the water looking sufficiently like a stick to fool their prey, and then Zip! SNAP! Munch munch, with their many, sharp, conical teeth.

A typical, adult longnose gar is at least 3 feet long, and individuals my grow to 6 feet and weigh 55 lbs. Their lifespan in the wild is more than 20 years. One captive specimen reached 39 years. They are a popular sport fish and show up on programs like “River Monsters.” (Warning: local news personalities making fish jokes in the following video.)

In addition to standard, line-and hook fishing, bowhunting for gar is popular, and some people on YouTube will show you how to prepare and cook them. Meanwhile, let’s talk about scales. Gar have ganoid scales, which are like a kind of crystal armor. Seriously. Ganoine, the key component, is an inorganic bone salt formed from apatite crystals. The serrated scales hook together for great flexibility and strength. This will be on the Aquatics test.

Longnose gar are a species of Least Concern. Their most significant vulnerability is that females begin laying eggs at 6 years old or older. Overfishing of younger females can significantly reduce the population in a particular habitat. Spawning occurs in spring/summer, and the eggs are deposited on rocky bottoms or ledges. They have an adhesive, toxic coating on them, and they hatch in about a week. The fry lurk in vegetation during their first summer, growing fast.

Past infancy, longnose gar have few natural predators. In coastal habitats, they may be snapped up by ospreys.

The UK Daily Mail has a piece about the LA bus stop décor.

It is supposed to be just the thing for the safety of "women and gender minorities," who, I guess, are supposed to climb to the top for their safety? There's a picture of the item and some women and/or gender minorities involved in the design. (I wonder what gender is indicated by the wearing of a mask below one's nose ...)
