Question

Order insectivore belongs to:
(a) Class Mammalia
(b) Class insecta
(c) Phylum Arthropoda
(d) Phylum Echinodermata

Answer 1

Hint:-One can say that the Insectivora can be defined as taxonomic order, however, it is obsolete. The term insectivore is still used to refer to the remaining members until today. The remaining are into three orders. They are Soricimorpha, Erinaceomorpha, and Chrysochloridea. We can say that the grand order Lipotyphla is the name given to these three orders together by many scientists. Also, the lipotyphla or insectivores are the names that refer to all of its members.

Complete step-by-step solution:-
One of the common names which can be applied to any of 450 or so species of mammals is
Insectivore. The class of Insectivore comprises of hedgehogs, golden moles, “true” moles, “true”
shrews, the moonrat, gymnures, solenodons, and tenrecs. They normally subsist primarily on
insects, other arthropods, and earthworms. Thus, we can conclude that almost 10 percent of all
mammal species can be included in the class of Insectivores. Also, most of these mammals are said
to be in the size of mice or small rats.
In general, the orders such as Phthiraptera, Psocoptera, Blattodea, and Odonata are included in the
class of Insecta.
In general, the orders such as Coleoptera, Diptera, Hymenoptera which includes the wasps, bees,
and ants) and Lepidoptera is included in Phylum Arthropoda.
The marine invertebrates of the order Clypeasteroida are generally included in the Phylum
Echinodermata.
Thus, the correct option is (a).

Note:- People say that most of the insectivores are either ground dwellers or burrowers. However, it is the fact that several are amphibious, and a few have adapted to life in the trees or forest understory. They hunt only invertebrates and small vertebrates. They have the ability to indicate an acute sense of smell. It is because their olfactory lobes of the brain are greatly developed.
