However, unlike their marine cousins, millipedes and centipedes are land dwellers. They are typically found in moist habitats or areas with high humidity and are most active at night. Millipedes and centipedes do not carry diseases that affect people, animals or plants.
Millipedes do occasionally damage seedlings by feeding on stems and leaves, and may enter homes in large numbers during periods of migration and become a considerable nuisance. They do not cause damage inside the home, although they may leave a stain if they are crushed. Centipedes, which have poison glands and can bite, pose an occasional threat to humans. Millipedes are often called 1,legged worms or rain worms. They are wormlike, with rounded body segments that each bear two pairs of legs.
The head is rounded with short antennae. Species can vary in length from less than 1 to 2 or more inches. They are typically light brown to black. Millipedes can climb walls easily and will often enter homes through foundation cracks above ground level.
Millipedes are not poisonous, but many species have glands capable of producing irritating fluids that may cause allergic reactions in some individuals. The defensive sprays of some millipedes contain hydrochloric acid that can chemically burn the skin and cause long-term skin discoloration.
The fluid can also be dangerous to the eyes. It is not advisable to handle millipedes with your bare hands. Persons handling millipedes may also notice a lingering odor on their hands. After contact with millipedes, wash hands thoroughly with soap and water until the odor is gone.
The solvents ether or alcohol will also help remove the noxious fluid. Although not too common, some centipedes are capable of staying alive in desert environments. Centipedes are predominantly flesh-eating creatures, and insects are their primary dietary preference. They also frequently eat spiders. Particularly big centipedes sometimes go after lizards. Although centipede bites can be ouch-inducing to humans, they're not fatal. Bites from bigger centipedes might be hazardous, however, which is why prompt medical attention is a must.

In addition to their many legs, centipedes have a number of unique characteristics not seen in many other modern arthropods: The first pair of legs on a centipede is modified to act similar to fangs. These legs are thickened compared to the rest of the legs, with sharp claws at the end.
On many centipedes, each one has a venom gland at the base that is used to deliver venom to prey and either kill or paralyze it. The last pair of legs is also specially-modified like the first pair. In this case, they are modified to act similar to antenna, giving the centipede a way to collect sensory information behind it. Centipedes do not have a waxy coating on their exoskeleton like most modern bugs, so they are prone to dehydration.
For this reason, most centipedes are nocturnal and many also prefer moist environments. Scott Zalewski was very professional. Michael did a great job. They simply lay eggs that are genetic copies of themselves. Only a few species are like this. There are some species that hatch as a larva and go through a pupal stage where they cocoon. Again, there are not a lot of species like this.
Some centipedes have a set of modified legs known as gonopods. These insects actually copulate and use these legs to transfer the sperm to the female during sex. The sperm is stored in a pore with a hood, then applied to the eggs after the female lays them.
Some centipedes are born with three legs. These centipedes add a pair of legs at every molt. Centipedes can get fairly large. Some of the larger ones are kept as exotic pets. Centipedes are carnivorous by nature, and use a venomous bite to paralyze their prey.
