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.
Structure. The primitive brain of the earthworm consists of two cerebral ganglia. Sensory nerves leave the brain and run forward to the first segment in the earthworm's body. The nerve cord travels from this first segment to the last.A fibrous sheath surrounds the nerve cord.hile humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side.
