For today’s post we return to the New York City Subway 8th Avenue local (B and C trains) station at 81st-Museum of Natural History,this time for the amphibians.
My favorite of the amphibians is this brooding caecilian, curled round its eggs. These legless, short-tailed amphibians are found only in the tropics, and there is no real English vernacular name for them. (You can find a Sicilian in the subway, but I prefer Neapolitan.)
What appears to me to be a reed frog (Hyperolius sp.), an African tree frog of sorts, hangs on the wall next to a station identifying sign.
This looks like a ranid frog to me– a member of the family Ranidae, perhaps intended to be a Rana proper. Many species in this and related genera look much alike the world over. Note the nicely delineated tympanic membrane.
This generic frog (I won’t even try to name a family for it) is leaping out of the Signal Room. Interestingly, the subway workers here believe in free will, apparently of the libertarian sort. A scratched note on the door reads, “Use other door→ | or this one– up to you”.
These well-rendered salamanders provide detail enabling specific identification. On the left we have a Marbled Salamander (Ambystoma opacum), a species of eastern North America (including the New York area), and on the right we have a Fire Salamander (Salamandra salamandra), a species widely distributed in Europe. The American Tiger Salamander (Ambystoma tigrinum; found in the New York area) is also black with yellow markings, but the yellow markings (quite variable in both species) look more like Salamandra to me, and the evident parotoid glands at the back of the head (making it look wide) are conclusive. Ambystoma and Salamandra are similar in size and body shape, and are sort of continental ecological analogues.
The Coelacanth (Latimeria chalumnae) is one of the few surviving lobe-finned fishes, and as such is one of the tetrapods closest living relatives, and so is included here as an honorary amphibian. I don’t know why there is a question mark on its tail; in fact I never noticed it there before till just now.
Finally, we have a group of patently Paleozoic fish. The artist has rendered them neither strictly from above (as though we were looking down on them in the ‘water’ of the paving tile) nor from the side, but in a sort of twisted view, allowing us to see various aspects. The bottom four may be intended to be the same type of fish (I’m not sure what kind), but the top one (which seems to be more of an exclusively side view– see the partly opened mouth) looks like one of those strange Paleozoic sharks, with a spiny first dorsal fin, and a heterocercal tail. You can also see more clearly in this photo how the lighter brown granite-like stone is integrated with the darker paving tile.
There are other taxa represented in the tiles (e.g., ants), and other forms of art, including larger tiled murals, and casts of in-situ fossils projecting from the wall. Many of these works are depicted in a gallery at www.nycsubway.org, a subway fan/history site. Some of those depicted I’ve never seen in person, because I always exit the station at the south (Museum) end, not at the north (81st Street) end.
(Looking at one of the pictures in the gallery now, I see the undersea mosaic mural has a coelacanth-shaped gray silhouette in the otherwise colorful tiles; could the question mark noted above be related to the coealcanth’s absence here?)
