There is considerable difference of opinion regarding the identity of the four Ilyodon “species.” Some authors believe them to be valid species in their own right, while others consider them all to be subspecies of I. furcidens. Generally speaking, I. furcidens and I. xantusi (Xantus’ Ilyodon) are believed to be very similar to each other—possibly variants of the single species, I. furcidens. Similarly, I. lennoni (Lennon’s Ilyodon) and I. whitei could be variants of I. whitei (White’s Ilyodon). All have similar behavior characteristics and aquarium requirements.
