Rabid bats usually lose their ability to fly, and rarely become aggressive. [49] Careless handling of bats is the main cause of rabies transmission. Since 2000, all the five human rabies cases contracted domestically in Canada were acquired from bats. [50] Fewer than 2% of bats in Canada are rabid, 95% of which are big brown bats.

Bats learn to avoid the harmful moths, but similarly avoid other species such as some pyralid moths that produce such warning sounds as well. Acoustic mimicry complexes, both Batesian and Müllerian, may be widespread in the ...

Vampire bats and Eulipotyphla are the only mammals so far observed to produce toxic saliva. These species have significantly enlarged and granular submaxillary salivary glands from which the toxic saliva is produced. [12] The Cuban solenodon (Atopogale cubana) and Hispaniolan solenodon (Solenodon paradoxus) look similar to large shrews.
