Zooids in a sentence

Colonies of some classes have various types of non-feeding specialist zooids, some of which are hatcheries for fertilized eggs, and some classes also have special zooids for defense of the colony.

These zooids appear in various positions: some take the place of autozooids, some fit into small gaps between autozooids, and small avicularia may occur on the surfaces of other zooids.

The zooids are attached to one another and physiologically integrated to the extent that they are incapable of independent survival.

A colony's zooids are connected, enabling autozooids to share food with each other and with any non-feeding heterozooids.

A few species can creep very slowly by using spiny defensive zooids as legs.

Although those of many marine species are protandric, in other words function first as males and then as females, their colonies contain a combination of zooids that are in their male and female stages.

Although those of many marine species function first as males and then as females, their colonies always contain a combination of zooids that are in their male and female stages.

Although zooids are microscopic, colonies range in size from convert to over convert.

Autozooids supply nutrients to non-feeding zooids by channels that vary between classes.

Bryozoans form colonies consisting of clones called zooids that are typically about convert long.

Eggs and sperm are released into the coelom, and sperm exit into the water through pores in the tips of some of the tentacles, and then are captured by the feeding currents of zooids that are producing eggs.

Even though colonies of zooids grow through asexual reproduction, Bryozoans are hermaphrodites and colonies are started through sexual reproduction.

In all species the founder zooids then grow the new colonies by budding clones of themselves.

In colonies of some species, signals are transmitted between zooids through nerves that pass through pores in the body walls, and coordinate activities such as feeding and the retraction of lophophores.

In some cases this response is more belligerent if the opposition is smaller, which suggests that zooids on the edge of a colony can somehow sense the size of the opponent.

In some species the snapping zooids are mounted on a peduncle (stalk), their bird-like appearance responsible for the term – Charles Darwin described these as like "the head and beak of a vulture in miniature, seated on a neck and capable of movement".

In species with calcareous exoskeletons, these do not mineralize until the zooids are fully grown.

On the other hand, the founding polyp of a coral has a shape like that of its daughter polyps, and coral zooids have no coelom or lophophore.

Phoronids resemble bryozoan zooids but are convert long and, although they often grow in clumps, do not form colonies consisting of clones.

Some encrusting colonies may grow to over convert and contain about 2,000,000 zooids.
