[2] Males also possess scent glands on the throat that secrete a viscous greasy fluid with a strong odour.

[2] The Sinaloan mastiff bat is found in western Mexico from Sinaloa southwards, in the Yucatán Peninsula, across Central America and Trinidad, and from northern Colombia across to The Guianas.

[1] Two subspecies are recognised: As much as 78% of the Sinaloan mastiff bat's diet consists of moths, although they also eat significant quantities of beetles and bugs, along with some other flying insects.

[2] Although they sometimes roost in caves,[3] they are more commonly found resting in palm trees or in cracks or cavities in artificial structures.

Weaning occurs at six to eight weeks of age, and females reach sexual maturity in their first year.
