Detailed explanation-1: -Symphylans are grouped in Myriapoda, a subphylum of arthropods containing millipedes, centipedes, and others. They are in their own arthropod class called the Symphyla.

Detailed explanation-2: -Many familiar species belong to the phylum Arthropoda-insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72). Arthropods are considered the most successful animals on Earth.

Detailed explanation-3: -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.

Detailed explanation-4: -Myriapods (Myriapoda) are a group of arthropods that includes millipedes, centipedes, pauropods, and symphylans.

Detailed explanation-5: -Arthropods are traditionally divided into 5 subphyla: Trilobitomorpha (Trilobites), Chelicerata, Crustacea, Myriapoda, and Hexapoda. Myriapoda is divided into four classes: Chilopoda (centipedes), Diplopoda (millipedes), Pauropoda, and Symphyla. Millipedes were likely the very first animals to live on land.
