Morphology
The compound is descriptive and literal: a 'kangaroo rat' is a type of rat with kangaroo-like jumping adaptations, so a learner who knows 'kangaroo' and 'rat' can infer it refers to a small, hopping rodent. This is a straightforward, non-idiomatic naming pattern found across languages and thus immediately comprehensible to B1 learners.
Etymology
Kangaroo rat comes from early observers who saw a small animal that looked like a rat but moved and carried its young in a pouch like a kangaroo. So the name helps you picture a tiny, hopping marsupial.
