The following cell structures can also be found in a typical animal eukaryotic cell: 1  Centrioles - help to organize the assembly of microtubules.â. 2  Chromosomes - house cellular DNA.â. 3  Cilia and Flagella - aid in cellular locomotion.â. 4  Cell Membrane - protects the integrity of the interior of the cell.â.
The rest of it is in its burrow. Earthworms are hermaphroditic, meaning they can all lay eggs after they mate. Earthworms lay coccoons which have an egg inside. Once an earthworm has hatched, it can live up to about three years.Earthworms have many predators, including: ants, mites, centipedes, earwigs, nematodes, fly larvae, termites, springtails, sowbugs, snails, slugs, spiders, birds, rats, mice, moles, toads, turtles, and snakes.ost native earthworms are thought to be long gone. Earthworms' bodies are soft and long with a cylinder shape. Nightcrawlers, the largest, can grow up to eight inches long. Their coloration is brownish-red. Earthworms live in soil in meadows, woods, stream banks, and lawns. They burrow up to six feet deep.
Habitat and Ecology: These worms live in muddy sediments, especially in shallow water along the edges of marshes and ponds throughout the United States, and many other parts of the world. Body and support: Mudworms usually have 150-250 body segments. They have no skeleton, but the fluid inside them gives them support and form.
