Grasshoppers have open circulatory systems, with most of the body fluid filling body cavities and appendages.

The one closed organ, the dorsal vessel, extends from the head through the thorax to the hind end.

The chemical reactions throughout their nervous system slowly destroys itself when in contact with Columbian bananas[citation needed].

Females lay up to 3,000 eggs in one or more silk egg sacs, which maintain a fairly constant humidity level.


Baby spiders pass all their larval stages inside the egg and hatch as spiderlings, very small and sexually immature but similar in shape to adults.


Some spiders care for their young, for example a wolf spider's brood cling to rough bristles on the mother's back, and females of some species respond to the "begging" behaviour of their young by giving them their prey, provided it is no longer struggling, or even regurgitate food.

Like other arthropods, spiders have to molt in order to grow as their cuticles ("skins") cannot stretch.

Amorphophallus is a large genus of some 170 tropical and subtropical tuberous herbaceous plants from the Arum family.

Once the spathe opens, pollination must happen the same day. The inflorescence, in many species, emits a scent of decaying flesh, in order to attract insects. Through a number of ingenious insect traps, pollinating insects are kept inside the spathe to deposit pollen on the female flowers, these stay receptive for only one day, while the male flowers are still closed. These open the next day, but by then female flowers are no longer receptive and so self pollination is avoided. The male flowers shower the trapped insects with pollen. Once the insects escape, they can then pollinate another flower.

is an insect of the order Lepidoptera. Like all Lepidoptera, they are notable for their unusual life cycle with a larval caterpillar stage, an inactive pupal stage, and a spectacular metamorphosis into a familiar and colourful winged adult form.

They are important economically as one of the major agents of pollination.

They are nested within the evolutionary tree of moths. Their origins may date back to the Cretaceous Period, ending 65 million years ago.

are notable for their hunting abilities. They are exclusively predatory, and their diet usually consists of living insects, including flies and aphids; larger species have been known to prey on small lizards, frogs, birds, snakes, and even rodents.

Prey are caught and held securely with grasping, spiked forelegs ("raptorial legs"); the first thoracic segment, the prothorax, is commonly elongated and flexibly articulated, allowing for greater range of movement of the front limbs while the remainder of the body remains more or less immobile.

The articulation of the head is also remarkably flexible, permitting nearly 300 degrees of movement in some species, allowing for a great range of vision (their compound eyes have a large binocular field of vision) without having to move the remainder of the body.

is a species of crab spider with holarctic distribution.

The color change is made possible by secreting a liquid yellow pigment into the outer cell layer of the body. On a white base, this pigment is transported into lower layers, so that inner glands, filled with white guanine, become visible. If the spider dwells longer on a white plant, the yellow pigment is often excreted.

They have been placed into an ancient group of insects termed the Paleoptera, which also contains the dragonflies and damselflies.

The adults are short-lived, from a few hours to a few days depending on the species.

In most species, the males' front legs are unusually long, for use in locating and grasping females during mid-air mating.

are semi-aquatic rodents native to North America and Europe. They are the only living members of the family Castoridae, which contains a single genus, Castor.

when startled or frightened, it will rapidly dive while forcefully slapping the water with its broad tail. This creates a loud 'slap', audible over large distances above and below water. This noise serves as a warning to other beavers in the area.

In herbalism it is used to treat kidney and bladder problems, gastro-enteritis, and prostate and urinary infections. Externally it is used for chilblains and wounds.

This plant also has a very high diploid number - 216 (108 pairs of chromosomes) - which is roughly 5 times bigger then human diploid number (46).

are a diverse group of more than 12,000 species, with a higher diversity in the tropics. They are known for their highly organized colonies and nests, which sometimes consist of millions of individuals. Individuals are divided into sub-fertile, and more commonly sterile, females ("workers", "soldiers", and other castes), fertile males ("drones"), and fertile females ("queens").

C
is the place where two lines of different dimensions meet at an angle, and a convex C* of intersecting walls is generally thought to be the least beneficial position to be in a life-or-death situation. From this notion was born the verb to C*, which is used to mean "To back (another person or animal) into a C*" and usually also carries a connotation of foul play.

ranging in size from 1 cm to 8 cm, they have eight eyes arranged in three rows.
Because they depend on camouflage for protection, they do not have the flashy appearance of some other kinds of spiders.

Their method of hunting is to run down their prey. They are robust and agile hunters that rely on good eyesight.

is a phrase which is shorthand for a concept relating to competition for survival or predominance. Originally applied by Herbert Spencer in his Principles of Biology of 1864, Spencer drew parallels to his ideas of economics with Charles Darwin's theories of evolution by what Darwin termed natural selection.
