Question

Write short note on Terrestrial life forms on earth.

Answer 1

here

Terrestrial animals are animals that live predominantly or entirely on land (e.g., cats, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g., fish, lobsters, octopuses), or amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g., frogs, or newts). Terrestrial invertebrates include ants, flies, crickets, grasshoppers and spiders.

The term terrestrial is typically applied for species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees.

There are other less common terms that apply to specific groups of terrestrial animals:

Saxicolous creatures are rock dwelling. Saxicolous is derived from the Latin word "saxum," meaning a rock.

Arenicolous creatures live in the sand.

Troglofauna predominantly live in caves.
