Elassomatidae, or Pygmy Sunfish, belong to the order Elassomatiformes. Elassomatidae are known collectively as Pygmy Sunfishes, but are not true sunfishes, which are members of family Centrarchidae. Some researchers believe they are related to sticklebacks and pipefishes (order Syngnathiformes) rather than Perciformes.
