Rock gunnel
The rock gunnel (''Pholis gunnellus'') is an eel-like fish found in the intertidal and subtidal zones of the North Atlantic. It is one of two species of gunnel native to the Atlantic Ocean, the other being the banded gunnel. The rock gunnel is capable of remaining above the waterline at low tide and breathing air.
==Physical characteristics==
The rock gunnel is often mistaken for an eel due to its flattened, elongated body. Fully grown adults can reach 30 cm in length. A long dorsal fin spans the body from just behind the head, supported by soft spiny rays. Its anal fin begins roughly midway along the body. The head is rather small with its lower jaw protruding and mouth turned upwards. Coloration is highly variable, ranging from hues of yellow-green to brown to crimson. A row of 9-13 dark spots, each surrounded by a pale ring, lines the dorsal fin.
