Hirola vs Topi: common questions
Are the hirola and topi closely related?
Yes, both species belong to the same broader antelope subfamily, Alcelaphinae, and share a similar overall build and horn shape, despite their dramatically different conservation status today.
Why is the hirola so much more endangered than the topi?
The hirola is restricted to a narrow range along the Kenya-Somalia border and has collapsed to fewer than 500 individuals due to disease, drought, and habitat loss, while the topi remains widespread and numerous across much of sub-Saharan Africa.
What makes the hirola taxonomically unique compared to the topi?
The hirola is the sole surviving member of its genus, Beatragus, meaning its extinction would end an entire evolutionary lineage, while the topi belongs to a genus, Damaliscus, that includes several other living species.
