Delphinus is one of the few constellations that actually looks like its namesake. When this distinctive asterism is viewed in a dark sky, it's easy to imagine it as a leaping Dolphin.

Equuleus, on the other hand, is a faint grouping that in no way resembles a horse of any size. It apparently gets its name due to the close proximity of Pegasus, The Winged Horse, which lies immediately to the east (left in this photograph).
