Venus Williams comments on Coco Gauff's picture from her day off at Adelaide Zoo

Coco Gauff put her day off during the Adelaide International to good use, visiting the zoo. The American shared her adventure on social media, much to the delight of tennis fans, including former World No. 1 Venus Williams.

Adelaide Zoo is the second oldest zoo in Australia, housing more than 3000 animals including 300 native and exotic species such as kangaroos and quokkas.

Gauff competed in Adelaide in 2021 as well, where she progressed as far as the semifinals before losing to Belinda Bencic. However, the COVID protocols last time around did not allow her to spend much time sight-seeing.

Speaking to journalists during her visit, Gauff said she was looking forward to spotting some "cool animals" and enjoying her time at the zoo.

"We are at the Adelaide zoo and I am hoping to meet some cool animals here," Coco said. "Last year, we did not do that much so I am glad to be out today and do something fun."

World No. 30 Karen Khachanov was spotted alongside Gauff. The pair visited various enclosures and were accompanied by zoo officials who gave them a formal tour of the place.

The American took to Instagram to share pictures she took to celebrate the occasion, evidently happy to be relaxing in the company of the zoo's inhabitants.

"Swipe left to see the monkey smiling for my selfie 😁🐵🤳🏾," Coco captioned her post on Instagram.

The post caught Venus Williams' eye, who agreed with Gauff's sentiment.

"He is def smiling! 😂😂👏", Venus commented on Instagram.

The 17-year-old also posted an Instagram story of Khachanov playing with a monkey. Gauff made no attempt to hide her laughter as the monkey outwitted the Russian to grab his stick.

"The monkey is 1-0 up on Karen Khachanov," Coco captioned the video on Instagram.
