As mammals, bats have a "hand" very similar to ours. The
of the fingers are elongated, and between them, as well as between the arm and the leg, a membrane has been created, called
, which allows it to perform an active flight.
Bats have great
but simply do not use (only) this sense to move in the most complete darkness. The adaptation to the night flight has produced the development of a complex system of
based on the emission and reception of ultrasound.
The species of bats that we can find in Europe are
and hunt exclusively during the
, when their preferred preys are plentiful. In winter, the strictest season, bats get into a condition of
, minimizing their vital functions and using the fat reserves, stored during the season.
In Europe there are 45 species of bats, each with precise ecological needs. If we wanted to classify them according to the type of
most used during the year, we could divide them into: those that use
(phytophilous), buildings (
) or caves and
(troglophilic).
