Gigitan

Apa kesan bisanya?

Its saliva contains a neurotoxic venom, which attacks the nerves. It delivers this venom at the base of the skull of its prey, and the venom paralyses prey even when the prey is larger than the shrew. Tests on field voles showed the venom is lethal at a minimum dose of 15 mg per kg of body weight.1

berguna untuk diketahui

Fakta

It is one of the few venomous mammals. Its venom comes from glands at the base of its lower front teeth, and grooves along the teeth channel the venom into the bite.1

Its teeth are tipped with red because of deposits of iron, which harden the enamel of the tips.1

It can dive up to two metres underwater and stay under for about twenty seconds before it must surface to breathe.1

Its short fur holds air, so its skin stays dry while it swims.1

It has a home range of about 500 square metres, but when foraging on land it can travel up to 3 km.1
