[1][2][3] Cubaris species have, on average, lower reproduction rates and longer lifespans than other genera of isopod.

[citation needed] Members of the genus Cubaris are well known for their ability to conglobate, or roll up into a ball, along with other genera such as Armadillidium.

[6] In recent years Cubaris has become a wastebasket taxon, resulting in many species being placed in the genus even when they do not necessarily fit the original description.

The hobby has expanded quickly in recent years, owed largely to Cubaris sp.

This undescribed Cubaris species garnered significant online attention, due to its face resembling that of a rubber ducky.
