Pika, camel, swallow, elephant or dolphin?
1. Pika is a tailless, egg-shaped, and short-legged mammal, related to rabbit, not rodent despite some similarities in their looks. Central Asia is one of pika’s primary residencies, in addition to China and Northern America.
2. Camels are nicknamed “ships of the desert” for its extraordinary ability to withdraw dehydration that is attributed to its body’s excellent adaptation to the extremely dry environment. Domestication of camels dated back to about 3,000 BCE around the Middle East and North Africa.
3. Swallows are often hailed as the “heralds of spring”. But they could travel up to thousands of miles before showing up on time in the vernal freshness of the land. Swallows make home at most parts of the world except for some remote islands and the coldest regions.
4. Elephant is the biggest land mammal on earth. Its characteristic trunk, boasting both strength and manoeuvrability, can undertake tasks from sucking water, picking up objects to sounding warnings or greetings to other elephants. And one of its tusks’ purposes is to protect the trunk, among others such as gathering food and digging to find water.
5. Dolphins are whales – toothed whales, to be more specific. Apart from being famously friendly and playful with humans, dolphins are also well-known for its intelligence. Bottlenose dolphins, for example, can recognizes themselves in the mirror, which indicates a degree of self-awareness, a capability that’s rarely discovered outside the world of higher primates.
