The chigoe flea (Tunga penetrans) is a parasitic arthropod found in tropical climates, especially South America and the West Indies. At 1 mm long, the chigoe flea is the smallest known flea. Breeding female chigoes burrow into exposed skin and lay eggs, causing intense irritation. After this point, the skin lesion looks like a 5 to 10 mm white spot with a central black dot, which are the flea's exposed hind legs, respiratory spiracles and reproductive organs.

An illustration of Cochineal living on cactus. Cochineal is the name of both crimson or carmine dye and the cochineal insect (Dactylopius coccus), a scale insect in the suborder Sternorrhyncha, from which the dye is derived. This type of insect, a primarily sessile parasite, lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid which deters predation by other insects. Carminic acid can be extracted from the insect's body and eggs to make the dye. Cochineal is primarily used as a food colouring and for cosmetics.

Mackerel is a common name applied to a number of different species of fish, mostly, but not exclusively, from the family Scombridae. They occur in all tropical and temperate seas. Most live offshore in the oceanic environment but a few, like the Spanish mackerel (Scomberomorus maculatus), enter bays and can be caught near bridges and piers. Common features of mackerels are a slim, cylindrical shape (as opposed to the tunas which are deeper bodied) and numerous finlets on the dorsal and ventral sides behind the dorsal and anal fins. The scales are extremely small, if present. The largest species called "mackerel" is the king mackerel (Scomberomorus cavalla) which can grow to 66 inches (1.68 m). A female mackerel lays about 500,000 eggs at a time

Tetraodontidae is a family of primarily marine and estuarine fish. The family includes many familiar species which are variously called puffers, balloonfish, blowfish, bubblefish, globefish, swellfish, toadfish, and toadies. They are morphologically similar to the closely related porcupinefish, which have large conspicuous spines (unlike the small, almost sandpaper-like spines of Tetraodontidae). The scientific name, Tetraodontidae, refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the shells of crustaceans and mollusks, and red worms, their natural prey. Puffer Fish are the second most poisonous vertebrate in the world, the first being a Golden Poison Frog. The skin and certain internal organs of many Tetraodontidae are highly toxic to humans, but nevertheless the meat of some species is considered a delicacy in both Japan (as fugu) and Korea (as bok-uh). If one is caught while fishing, it is recommended that thick gloves are worn to avoid poisoning and getting bitten when removing the hook.

An illustration of the larva of a common flea. Flea larvae emerge from the eggs to feed on any available organic material such as dead insects, feces and vegetable matter. They are blind and avoid sunlight, keeping to dark places like sand, cracks and crevices, and bedding. Given an adequate supply of food, larvae should pupate within 1-2 weeks. After going through three larval stages they spin a silken cocoon.

An illustration of a common flea. Once the flea reaches adulthood its primary goal is to find blood - adult fleas must feed on blood in order to reproduce. Adult fleas only have around a week to find food once they emerge, though they can survive two months to a year between meals. A flea population is unevenly distributed, with 50 percent eggs, 35 percent larvae, 10 percent pupae and 5 percent adults. Their total life cycle can take as little as two weeks, but may be lengthened to many months if conditions are unfavorable. Female fleas can lay 500 or more eggs over their life, allowing for phenomenal growth rates.

The pea crab is a small crab in the family Pinnotheridae that lives symbiotically in oysters, clams, mussels and other species of bivalves. The crab is usually about the size of a pea but can grow as large as a small walnut. It is also commonly known as the oyster crab. Females have a large tail flap that is used to cover eggs attached to the bodies when they are breeding, adding to the spherical appearance.

The sponges or poriferans (from Latin porus "pore" and ferre "to bear") are animals of the phylum Porifera. Their bodies consist of an outer thin layer of cells, the pinacoderm and an inner mass of cells and skeletal elements, the choanoderm. Sponges do not have nervous, digestive or circulatory systems. Instead most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow.

Under certain circumstances some cells may store up food matters beome eggs, while others, known as sperm-cells, develop a flagellum. These reproductive cells separating from the colony they swim actively uniting with an egg. This union of two individuals in Vorticella results inthe power of division. The cells produced remain together, form a spere, and finally develop a Volvox colony.

Threadworm (Nematodes) or Roundworm is composed of many different species. In all the body is slender as in the "vinegar eel". This small worm, a millimeter or two in length, lives on the various forms of mold that grow in fermenting fruit juices. A tough cuticle surrounds the body, perserving its shape and at the same time protecting the delicate organs against the action of the acids in which it lives. In the treadworm the eggs develop within the body and the young are born with the form of the parent.

In the Trichina, a parasitic roundworm, the bodies of several animals, particularly the rat, are host for developing eggs. If the rat is eaten by a carnivorous animal, these excessively small young are liberated during the process of digestion and rapidly assume the adult condition in the alimentary canal, giving rise to young which pursue again the same course of development.

Bees are flying insects closely related to wasps and ants. Honey bees (or honeybees) are a subset of bees, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax. A colony generally contains one queen bee, a fertile female; seasonally up to a few thousand drone bees or fertile males; and a large seasonally variable population of sterile female worker bees. Eggs are laid singly in a cell in a wax honeycomb, produced and shaped by the worker bees. Larvae are initially fed with royal jelly produced by worker bees, later switching to honey and pollen.

Sacculina is a genus of barnacles that parasitize crabs. The female Sacculina larva finds a crab and walks on it until it finds a joint. It then molts, injecting its soft body into the crab while its shell falls off. The Sacculina grows in the crab, emerging as a sac, known as an externa, on the underside of the crab's rear thorax, where the crab's eggs would be incubated.

Ichneumon flies are solitary insects, and most are parasitoids—the larvae feeding on or in another insect which finally dies. As with all hymenopterans, ichneumons are closely related to ants and bees. The female finds a host and lays an egg on, near, or inside the host's body. Upon hatching, the larval ichneumon feeds either externally or internally, killing the host when they themselves are ready to pupate. The large ichneumon fly (Thakessa), with long flexable ovipositor, boring to deposit eggs.

An insect known as the pigeon horntail (Tremex columba) deposits its eggs, by means of a strong, piercing ovipositor, half an inch deep in the trunk wood of growing trees. Female uses ovipositor to bore through bark into wood, depositing 1 slender egg in each hole. Eggs are covered with fungal spores from a special pocket in female's abdomen. After depositing the last egg, the female often dies without removing its ovipositor from the wood. The dead female becomes food for some insectivorous animal.

"The first change in the parent-cell is that by which it becomes broken up into a mass of cells, each of which is just like itself. This process is called segmentation of the vitellus; each one of the numerous resulting cells is called a cleavage-cell. The nucleus of the parent-cell divides into two; each attracts its half of the yelk; the halves furrow apart and there are now two cleavage cells in place of the one parent-cell a furrow at right angles to the first, and redivision of the nuclei; results in four cleavage-cells. Radiating furrows intermediate to the first two bisect the four cells, and would render eight cells, were not these simultaneously doubled by a circular furrow which cleaves each, with the result of sixteen cleavage-cells. So the subdivision goes on until the parent-cell becomes a mass of cells. This particular kind of cleavage, by radiating and concentric furrowing, is called discoidal, and the resulting heap of little cells assumes the figure of a thin, flat, circular disc. Segmentation of the vitellus, in whatever manner it may go on, results in a mulberry-like mass of cleavage-cells; and the original cytula has become what is called a morula. This process is shown closely here." Elliot Coues, 1884

The Boat-billed Flycatcher, Megarynchus pitangua, is a passerine bird. It is a large tyrant flycatcher, the only member, monotypic, of the genus Megarynchus. It breeds in open woodland with some tall trees from Mexico south to Bolivia and Argentina, and on Trinidad. The nest, built by the female, is an open saucer of sticks. The typical clutch is two or three whitish eggs heavily blotched with brown. These are incubated mostly by the female for 17-18 days with a further 24 days to fledging.

The megapodes, also known as incubator birds or mound-builders, are stocky, medium-large chicken-like birds with small heads and large feet in the family Megapodiidae. Their name literally means large foot and is a reference to the heavy legs and feet typical of these terrestrial birds. All are browsers, all but the Malleefowl occupy wooded habitats, and most are brown or black colored. Megapodes are superprecocial, hatching from their eggs in the most mature condition of any birds. They hatch with open eyes, with bodily coordination and strength, with full wing feathers and downy body feathers, able to run, pursue prey, and, in some species, fly on the same day they hatch.

The Common Mudpuppy (Necturus maculosus) is a species of aquatic salamander found throughout the northeastern United States, and parts of Canada. Mudpuppies prefer shallow water with many places to hide, but have been found at depths of up to 90 feet. The mating season is late autumn, however eggs are not laid until late spring when 50 to 100 eggs are deposited in a nest cavity under a rock or other object. It takes 1 to 2 months for the eggs to hatch and 4 to 6 years for the young to reach maturity. Mudpuppies may live for up to 20 years.
