Najin, one of the last two northern white rhinos on the plant, is mother to Fatu, and the daughter of Sudan.
She's a cool, calm, sociable lady who likes to be around her daughter and Tauwa, their southern white rhino companion.
She gets very excited by water and rain. Due to deformities in her hind legs, however, she can't run as fast as she'd like to keep up with the other two.
She loves food and can occasionally be a little naughty, earning her the moniker Naughty Najin. She is photographed here with Zacharia Mutui.
Fatu, one of the last two northern white rhinos on the planet, is daughter to Najin, and the granddaughter of Sudan.
Fatu is crazy about water and the rain. Her head picks up, her ears are pricked and she runs off with her southern white rhino best friend Tauwa to the mud pits to wallow. She loves being in standing water.
She sleeps beside her best friend Tauwa. While the friendship is adorable, occasionally her mother, Najin, has to nudge the two girls back in line with her horn when they get a little too rambunctious.
Baraka is a blind, black rhino. He is Ol Pejeta's official rhino ambassador. He is friendly and loving, especially towards women.
Because he is blind, his senses of hearing and smell are stronger that those of black rhinos in the wild.
He's not a morning person, and often refuses to wake up when his rangers call him. He dedicates half of his day to sleeping and the other half to eating.
One of his favorite pastimes is escaping from his 100-acre enclosure to mark his territory outside the boundary fence, then sneaking back as if no one has noticed.
As a model for conservation and a beacon of hope for critically endangered wildlife species, Ol Pejeta's mission to conserve biodiversity for future generations requires significant financial resources. Learn more about their work and all the ways you can get involved by visiting their website.
Zacharia and I both would like to express how grateful we are that you are spending time with this story and that you care as much as we do about these hulking, ancient, gentle giants. Thank you for being a part of this.
