It is hard to guess what a Proboscis bat weights. But we have the answer:
An adult Proboscis bat (Rhynchonycteris naso) on average weights 4 grams (0.01 lbs).
The Proboscis bat is from the family Emballonuridae (genus: Rhynchonycteris). It is usually born with about 1 grams (0 lbs). When reaching adult age, they grow up to 4.2 cm (0′ 2″). Normally, Proboscis bats can have babies 2 times a year.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The proboscis bat (Rhynchonycteris naso) is a bat species from South and Central America. Other common names include Long-nosed proboscis bat, sharp-nosed bat, Brazilian long-nosed bat and river bat in English, and murciélago narizón in Spanish. It is monotypic within its genus.This species is in the family Emballonuridae, the sac-winged or sheath-tailed bats. Like most bats, it is nocturnal. It is found from southern Mexico to Belize, Peru, Bolivia and Brazil, as well as in Trinidad.
