The new photos, which were taken secretly at a Chinese quarantine facility, show that the most recent "shipment" of babies was no exception.
Joyce Poole, co-founder of Kenya-based advocacy group Elephant Voices, told National Geographic that the photos show the latest babies with a number of injuries.
Poole says the elephants - many as young as four - have protruding cheekbones, lackluster skin, a mottled complexion - which signifies poor condition - and abrasions.
She speculates that the wounds may have been inflicted by people, or by infighting among the elephants, or during their journey from Zimbabwe to China. Or indeed by a combination of all three.
Many of the injuries "are consistent with bullhook wounds," Poole says, which are sometimes used in transporting and disciplining elephants. (Bullhooks are poker-like, metal instruments traditionally used to "train" elephants.)
The baby elephants are currently living in concrete enclosures and are visibly emaciated.
