Here's why:
* Memory Research in Kangaroos: Research on kangaroo memory is limited, and there isn't enough evidence to definitively claim they have exceptionally sharp memories.
* Other Animals with Remarkable Memory: Animals like elephants, dolphins, crows, and even some species of fish have been shown to have exceptional memory capabilities, often exceeding human memory in specific areas.
It's important to avoid generalizing about animal intelligence and memory. Each species has unique cognitive abilities, and more research is needed to understand the nuances of kangaroo memory.
