It was discovered by French astronomer, Stephane Javelle on November 25, 1897^[3] and is probably gravitationally bound to IC 5338, the brightest cluster galaxy in Abell 2626. According to SIMBAD, IC 5337 is considered an emission-line galaxy.^[4]

IC 5337 is a jellyfish galaxy, mainly due to ram pressure.^[5][6][7] Star-forming gas are thrown about, as the galaxy penetrates through the thin gas layer and causing them to drip from the galaxy's disc, giving it its unique appearance of a cosmic jellyfish.^[5] It has a stellar mass of 3.2 × 10¹¹ M_⊙^[8] and contains an active galactic nucleus likely trigged by accretion of matter into its supermassive black hole.^[9]

In addition, IC 5337 also shows an X-ray source.^[10]
