Behaviour and ecology
Smeringurus mesaensis is fossorial and solitary, though young will aggregate shortly after dispersing from their mother. Females of this species are typically larger than males,[4] with males traveling to find females during mating season.[5] They are nocturnal creatures, active between 9 p.m. and 3 a.m., accounting for their daytime invisibility.[6]
