Do centipedes reproduce sexually or asexually?
In most species of centipede reproduction occurs sexually but there are some species where only females occur and reproduction is through parthenogenesis. Centipedes do not reproduce via direct copulation, instead the male produces a spermatophore for the female to take up.
How do centipedes and millipedes reproduce?
The centipede reproductive cycle involves distinct rituals. The female centipede first releases pheromones to attract a male, who, in some species, then weaves a silk pad deposited with sperm, known as a spermatophore. Centipedes lay their eggs in the hollows of rotting logs or in the soil.
What are the 4 classes of the subphylum myriapoda?
The Myriapoda consists of four classes of terrestrial arthropods (Chilopoda, Diplopoda, Symphyla, and Pauropoda) that share a number of morphological features.
What phylum are millipedes?
Arthropod
Millipedes/Phylum
What class is a millipede in?
class Diplopoda
Answer. While both millipedes and centipedes belong to the phylum Arthropoda and to the subphylum Myriapoda, millipedes belong to the class Diplopoda and centipedes belong to the class Chilopoda.
How do centipedes reproduce?
Centipedes reproduce by laying eggs, usually in the soil. There are many different kinds (species) of centipedes. In some species the mother just leaves the eggs where they are laid. In other species the mother stays and protects the eggs.
Can centipedes reproduce asexually?
Some centipedes reproduce via parthenogenesis. This is an asexual reproduction where all the insects are females. 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.
What is the phylum of centipede?
Centipedes/Phylum
What two classes are under the subphylum Myriapoda?
The members of the subphylum Myriapoda are in the classes Diplopoda, Chilopoda, Pauropoda, and Symphyla. 3. Members of the subphylum Hexapoda are characterized by three pairs of legs and three tagmata. They are divided into two classes, Entognatha and Insecta.
What are the sections of a millipede called?
The body is divided into two parts, the head and a segmented trunk. Millipedes breathe through spiracles, holes positioned in paris along the body. The top of each segment is called the tergite (or tergum); the underside (between the pairs of legs) is called the sternite (or sternum).
What is the classification of myriapods?
Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains over 16,000 species, most of which are terrestrial. Although their name suggests they have myriad (10,000) legs, myriapods range from having up to 750 legs (the millipede Illacme plenipes) to having fewer than ten legs.
Which arthropod group is most closely related to Myriapoda?
There has been much debate as to which arthropod group is most closely related to the Myriapoda. Under the Mandibulata hypothesis, Myriapoda is the sister taxon to Pancrustacea, a group comprising the Crustacea and Hexapoda (insects and their close relatives).
How old is the phylum Arthropoda?
History of Phylum Arthropoda The origin of arthropods is very ancient, more than 500 million years ago. The most ancient arthropod fossil appeared in the Cambrian period (541.0 million to 485.4 million years ago), represented by trilobites, merostomes and crustaceans.
What is the fossil record of myriapods?
The fossil record of myriapods reaches back into the late Silurian, although molecular evidence suggests a diversification in the Cambrian Period, and Cambrian fossils exist which resemble myriapods. The oldest unequivocal myriapod fossil is of the millipede Pneumodesmus newmani, from the late Silurian (428 million years ago).
