RACE OF LIFE (EP. 12)
RACE OF LIFE (EP. 13)
EP. 13. In this episode we explore the Race of Life on a small scale but no less competive or cruel for all that. Insects burrow through the ground, hop and sing in the trees, and dart and dance in the air. They come in many different colors and shapes. There are many reasons why insects are so successful at surviving. Their ability to survive in all kinds of temperatures and environments. A strong, hard but flexible shell called an exoskeleton covers their soft organs and is resistant to chemicals, water and physical impact. Their wings give them the option of flying away from dangerous situations or toward food or mates. In this episode: Dragonflies hover like helicopters over ponds and lakes, then suddenly dart away, pursuing prey or other dragonflies. The monarch butterfly goes through a miraculous metamorphosis, changing from an egg to a hungry caterpillar to a quiet pupa and emerging as a beautiful winged adult. The praying mantis is master of disguise. Its green body, wings and legs merge into the green, leafy background so carefully it seems to be part of the grass. Perched at an angle, with its spiny forelegs raised in a prayerlike pose, the mantis sits in still rigidness - until another insect such as a fly comes too near and is suddenly captured and devoured. Ants, like bees, hornets and wasps, are social insects and live together in colonies in many-chambered nests. Whatever it takes, to stay in the race.

EP. 12. The ocean can be an unforgiving place. Animals living in the sea have to deal constantly with finding food, and protecting themselves from predators. There are many ways of hiding, defending, and feeding, and every different technique has advantages for different animals. For example, some animals use camouflage to escape detection or to sneak up on their prey, while other animals have coloration which intentionally makes them stand out. Some creatures hide from predators, while others stay in groups, out in the open, relying on safety in numbers. Some animals have dangerous spines or venom for protection, but even the most venomous creatures must sometimes be wary of predators. Different animals have taken advantage of different food sources, some feeding at the top of the food chain, and others at the bottom. Protecting themselves underwater is also a matter of invention and reinvention, and aquatic animals deploy an array of strategies just to stay alive. They have quite the toolbox to dip into – Evolutionary strategms such as colour and camouflage, toxins and teeth! Nudibrancs, clown fish, squid, octopus and orca whales are just some of the wonderful winners in the underwater race of life. Underwater footage shot in the wild, demonstrates vividly how these ocean creatures have evolved to survive by adapting to their environment.
