If we enlarged a spider to the size of a human being, the web it weaves would be around 150 meters high. That is the same height as a 50-storey skyscraper.
Each eye of a dragonfly contains about 30,000 lenses.
The housefly's eye is composed of 6,000 hexagonally arranged eye structures.
A falcon maintains absolute balance while diving for its prey at a speed of 384 km/h.
Honeybees, wasps and flies flap their wings 200 to 400 times per second. This rate goes up to 1,000 in sandflies and some 1mm long parasites.
The albatross has a wingspan of 3 meters.
The body temperature of a sparrow can rise to as much as 48°C due to its fast metabolism.
A mother bird understands whether her chicks need food or not from the colours of their gapes.
The Misumena varia species of crab spiders can assume different colours ranging from yellow to white, depending on the flower on which they land.
Some insect species protect themselves from their enemies by means of group camouflage.
Most of the life forms that emerged all of a sudden in the Cambrian Period had complex systems like eyes, gills, circulatory system, and advanced physiological structures no different from their modern counterparts .
Spider silk is thinner than human hair, lighter than cotton and stronger than steel, and is recognized as the strongest material in the world.
The sleeping dolphin uses the right and left hemispheres of its brain alternatively. This system prevents the death of the creature during its sleep under water.
The penguins live in a place where the temperature falls to -400C (-40oF).
Spider silk has a tensile force of 150,000 kilograms per square meter.
If a rope, 30 centimeters in diameter, were made out of spider silk, it could bear the weight of 150 cars.
When giraffes bend down, the valves in their neck vessels are shut down and they prevent excess blood from flowing to the brain.
The bombardier beetle can store hydrogen peroxide and hydroquinone in its body to squirt towards the enemy to protect itself in moments of danger.
The jumping spider's eyes can see independently from each other, which helps the animal perceive objects more rapidly.
The heat-detectors located in the facial cavities at the anterior of the rattlesnake's head are so sensitive as to perceive a temperature increase of 1/300 in the heat of the setting.
The heat receptors of the gnat are sensitive enough to detect heat differences as small as 1/1,000o C.
The gnat has nearly one hundred eyes.
A special liquid is secreted in the gnat’s body which neutralizes the enzyme that causes the clotting of blood of the creature it has stung.
The camel can survive without food and water for eight days at a temperature of 50°C.
The camel increases its internal temperature to 41°C and as such keeps water loss to a minimum in the extreme hot climates of the desert daytime.
Camels can consume up to 130 liters of water, which is around one third of their body weight, in almost 10 minutes.
Although a humped camel can take in 30-50 kilograms of food in a day, in tough conditions it is able to live up to one month with only 2 kg of grass a day.
Although a humped camel can take in 30-50 kilograms of food in a day, in tough conditions it is able to live up to one month with only 2 kg of grass a day.
Desert camels are not affected by high temperatures up to 50°C, and double-humped Bactrian camels can survive in very low temperatures down to -50°C.
