This is similar to be an Aussie lol, we wear shorts and t shirts in the winter lol. This guy is great, it doesn’t snow in Sydney so i drove a few hours to see some very light snow and it only snows there every few years so it was exciting lol.
That would be “Mud Eel” (Heterenchelyidae). Was popular in the St-Lawrence Bassin and seasonally caught when the tides would go down (circa 1920 to ’40s, IIRC). Fish family.
