The maned rat spreads the plant's poison on its fur and becomes poisonous.

Its name is the maned rat or crested rat.

Some rare species, such as the giant forest hog, suni, mountain bongo, and maned rat are found in the forest.

Lophiomyinae (Maned rat or crested rat)

These include the maned hamster, or crested hamster, which is really the maned rat (Lophiomys imhausi).

The East African maned rat (Lophiomys imhausi), an arboreal, porcupine-like rodent, has four digits on their hands and feet and a partially opposable thumb.

The maned rat or crested rat (Lophiomys imhausi) is a nocturnal, long-haired and bushy-tailed East African rodent that superficially resembles a porcupine.

The habitat of the maned rat ranges from nearly sea level, in Ethiopia and Somalia, to more typically the drier, highland forests and woodlands of Somalia, Ethiopia, South Sudan, Sudan, Tanzania, Uganda and Kenya.

One unusual case is the African crested rat.

Its name is the maned rat or crested rat.

The African crested rat is a large gray rodent that lives in (wait for it...) Africa.

And as imprecise, since readers should know the crested rat lives more precisely in East Africa, where this poisonous tree grows (which you mention.)

Bizarre rat reveals toxic trick The African crested rat applies toxins from a poisonous tree to its fur to foil predators, scientists report.

They found that the African crested rat chews the roots and bark of a highly toxic tree, and then smears the lethal mixture on its specially adapted fur.

But an in-depth study of the African crested rat shows that this display, as well as the morphology of the rat, is a highly evolved method to deter predators.

The maned rat or crested rat (Lophiomys imhausi) is a nocturnal, long-haired and bushy-tailed East African rodent that superficially resembles a porcupine.

Last week's issue of Proc B reports that the African crested rat chews bark from a particular plant, then smears the slimy paste onto specialized hairs that can deliver the toxin to a hungry predator's mouth.

The African crested rat (Lophiomys imhausi) is found in the north east of continent, and has long been thought to be poisonous: there have been several reports of domestic dogs that have dropped dead after trying to bite one.
