SAN ANTONIO – It’s a boy!
The San Antonio Zoo announced Tupi, the baby capybara, is a boy at a gender reveal on Wednesday morning.
A sign above Tupi’s habitat depicted the capybara on a boat and read: “Ahoy! It’s a boy!”
Tupi could be seen feasting on watermelon and other snacks with the other two capybaras inside the Capybara Habitat.
Tupi, pronounced “two-pee,” was born on Dec. 3, 2024, and is the first capybara to be born at the zoo since 2000.
Videos posted online have earned the baby capybara fans around the world.

Capybaras are the world’s largest rodent species. According to the San Diego Zoo, like many rodent species, capybaras lack visible signs to indicate its sex until they reach maturity.
