What is the mating behavior of the Mexican burrowing toad?

• A. Calls for a mate after heavy rains.
• B. Mates with a loud drumming display.
• C. Mates after drought.
• D. Mates with multiple partners in a season.

Answer: (A)

Heavy rainfall acts as the cue for mating in the Mexican burrowing toad. These toads spend most of the year underground, but after rains they emerge to use temporary pools that form as breeding sites. Males call to attract females from the water, advertising themselves so females can choose a mate, and eggs are laid in those ephemeral pools. This rainfall-triggered emergence and vocal advertisement is the key pattern, whereas drought conditions wouldn’t provide the water needed for eggs and tadpoles, and a loud drumming display isn’t the characteristic mating signal for this species. Mating with multiple partners can occur in many amphibians, but the distinctive, correct behavior here is the call after heavy rains to reproduce.
