Question

Cockroach belongs to which phylum? Give other examples of the same phylum.

Answer 1

Hint: Cockroaches are categorized by their jointed appendages, which are their legs, and tough exoskeletons. An exoskeleton is basically what it sounds like: an external skeleton.

Complete answer:
Arthropod, any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such common forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. Near about 83 percent of all known species of animals are members of this phylum.

Arthropods are represented in every environment on Earth and show a great diversity of adaptations. Several types live in aquatic environments, and others live in terrestrial ones; few groups are even adapted for flight.

Cockroaches fit in the phylum Arthropoda which is the biggest phylum in the kingdom of Animalia. The other animals which include in the arthropods' phylum are Spider, Butterfly, Crab, Scorpion, Centipede, Prawn, and Grasshopper.

Additional information:
- The unique feature of arthropods is the presence of a jointed skeletal casing composed of chitin (a complex sugar) bound to protein. This nonliving exoskeleton is secreted by the underlying epidermis. Arthropods are devoid of locomotory cilia, even in the larval stages, perhaps because of the presence of the exoskeleton.

- The body is frequently segmented, and the segments bear paired, jointed appendages, from which the title arthropod (“jointed feet”) is derived. Around 10 lakhs arthropod species have been described, of which most are insects.

Note: Zoologists have approximated the total figure of insect species alone to be as high as 10,000,000. The 30,000 mentioned species of mites may also represent only a proportion of the existing number.
- The phylum Arthropoda is commonly separated into four subphyla of extant forms: Chelicerata, Crustacea, Hexapoda, and Myriapoda.
