Which gland of the cane toad produces poison?

a. parotoid gland

b. tympanic membrane

c. glottis

d. eustachian tubes

The correct option is: a. parotoid gland

Explanation:

Cane toads, also known as Bufo marinus or Rana marina Linnaeus, are the giant old species of the terrestrial true toads. The female cane toads are longer than the male cane toads.

The skin of the cane toad is highly toxic. An adult cane toad has large parotoid gland behind each eye, which secretes a milky-white toxic fluid called bufotoxin.
