The white-winged vampire bat is a small bat that feeds on blood. It lives from Mexico to northern Argentina, and also on the islands of Trinidad and Margarita Island. Its pale wing edges make it easy to tell apart from some of its relatives.1

Često se miješa s: It is often confused with the common vampire bat. The white-winged vampire bat has a smooth outer edge on its tragus (the small flap in front of the ear), while the common vampire bat's is serrated. Its thumb is also much shorter, and it has 22 teeth, compared with 20 in the common vampire bat.1

Otrovna snaga

Ugrizi

Otrov izlazi kroz očnjake ili zube kad ugrize.

Što radi njegov otrov kad ugrize ili ubode?

Its saliva contains plasminogen activators, which quickly dissolve the clots that form in the host's blood while it feeds. It also contains platelet aggregation inhibitors and other anticoagulants, which stop blood from clotting. These compounds work especially well on birds.1

Koliko je opasno za ljude?

Opasnost za ljude: BlagoKao ubod pčele ili slabije. Uglavnom bezopasno za ljude.

It can transmit rabies, but this appears to be relatively uncommon. The only reports of rabies transmission from this species come from Trinidad.1

Što radi kad se uplaši?

When disturbed, it produces a foul-smelling odour from cup-shaped scent glands in its mouth, which may help deter predators.1

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

In captivity, each bat drinks about 16 ml of defibrinated cow or chicken blood per day, and they should be kept in social colonies with dominance hierarchies.1

It is the only bat species in the world with 22 teeth, although older individuals sometimes lose the last upper molars.1

Its brain is large for its body size, which may be because its hunting needs careful planning and stealth.1

It is not as good as the common vampire bat at walking on all fours, but it is quite good at climbing branches.1

It roosts with many other bat species, including the common vampire bat.1
