Venezualan specimens were collected in many different habitats, but mostly in moist, open areas of the forest (Nowak, 1997). One specimen was found in cavity in the ground (Murcielagos, 1982). Venezuelan samples were taken at up to 2240 m (Eisenberg, 1989).
Physical Description

56 to 58 mm
(2.20 to 2.28 in)
Sphaeronycteris toxophyllum has a total length of approximately 56-58 mm and a forearm length of about 40 mm. There is no external tail and the dorsum is cinnamon brown. The underparts are brownish white with individual hairs on the back whitish. The side of the face has fleshy outgrowths. A hornlike growth on the nose is larger on males than on females. Under the chin is a fold of skin that can be rolled over the face. The bat is similar in appearance to Centurio but with less extreme facial outgrowths and a third lower molar (Nowak, 1997).
Behavior
There is no literature regarding the behavior of this species.
Food Habits
Unknown food habits, but the stomach contents of an examined specimen resembled yellowish fruit pulp (Murcielagos, 1982).
Ecosystem Roles
Not much is known, but because they are frugivores it might be assumed that they disperse some fruit seeds.
