There’s big reason to celebrate at the San Diego Zoo, as our young river hippo has just had his first birthday. It’s hard to believe, but little Adhama is a year old and now weighs a whopping 860 pounds (390 kilograms). To celebrate the occasion, Adhama and his mother, Funani, got to enjoy their favorite treat: watermelon! Of course, when you’re dealing with hippos, a couple of melons don’t last very long. Watch the fun below!
It’s been quite an exciting time. Adhama has enjoyed a lot of attention from his mother, his keepers, and even the media. After a video of the boisterous calf, titled “Baby Hippo Ballet” went viral, Adhama was seen on local and national television, in an article in our member magazine, ZOONOOZ, and in People magazine, where he was given a one-page spread.
It will still be several more years before Adhama is considered fully mature. In the meantime, Funani is more than happy to spend time with him and seems reluctant to cut the apron strings. As Adhama starts to show more independence, it is Funani who tends to rein him in. And whereas most hippo calves are fully weaned by six to eight months of age, Adhama can still be seen nursing occasionally.
He has met his father, Otis, through the safety of a closed gate with visual access to one another. Adult male hippos sometimes kill youngsters, and while Otis has not shown any signs of aggression toward his son, there are still no plans to put him with Funani and Adhama. Therefore, on Mondays, Wednesdays, and Fridays, Otis has his turn on exhibit.

Thank you for the update! The little fella certainly has grown. At what age will he start getting his tusks? Has he been getting any type of training yet? Great blog and vid. Thanks again!
Happy 1st birthday Adhama!!
You are soo cute!
See you soon at SDZ!
Love,
Seiko
How much did he weigh when he was born? (or when he was first weighed?)
Average hippo calves are between 50 and 100 lbs at birth. We did not get a weight on Adhama until he was about 6 months old. At that point, he was already 480 lbs. (220 kg.)
Thanks for the update Nate. I got to see Adhama last March during the panda convention and just fell in love with him. Hopefully he will be at the zoo for a couple of more years so I can see him again.
