Which Mammal lays Eggs?

Fri, 16 May 2003 08:54:38 +0000

Mammals are creatures who give birth to their young ones as opposed to other animals who lay eggs. Birds, reptiles and insects lay eggs. But as with every other rule, this one has exceptions* too.

An exceptional exception

The duck-billed platypus of Australia walks out of fresh waters to build its nest on the ground. But it has retained its love of water and returns to streams and ponds to eat crayfish, snails, and shrimp. The most remarkable feature in the platypus is that although it is a mammal, it lays eggs!

The oldest living creature in the world will come as a surprise to you. Many of the animals in the seas, skies, and earth live long lives. Yet the oldest living creature in the world is an immortal jellyfish that has never died. Its family name is Turritopsis Dohrnii. It hails from a class of small animals that live mainly in saltwater.

The Dohrnii begin their life journey as larvae with a diameter of no more than 4 millimeters. The larvae have a tiny vase-shaped body with a mouth surrounded by tentacles. They come together and attach themselves to the ocean floor. Soon, they mature into jellyfish. Once they mature, they travel great distances and hunt other fish for food. The Dohrnii has currently spread across three continents by hitchhiking on the underside of cargo ships. Due to their tiny size, the countries they are invading are unaware that it is even happening.

Take a look around. Which insects do you see? A fly sitting on your computer screen, a mosquito buzzing in your ear just as you drop off to sleep, a butterfly flitting about in the garden outside, or how about the ants that made off with the remains of a dead moth?

Most of the insects we see around us have rather short lives. A few hours, a few days, that’s about how long most insects last. We don’t notice them dying out because they’re promptly replaced by a new bunch. Yet, some insects live comparatively really long lives.
