Using any or all of your 9 or so senses to examine your environment is organoleptic analysis.
No, it is not. Your various senses have the job of sensing your environment.
Yes, the slater, also known as the woodlouse or "roly poly bug" is an arthropod, of the family Armadillidiidae. They are among the crustacean arthropods that can be found on land, though they need to be in a moist environment. Sometimes they are confused with the pill millepede which looks pretty similar (and is also an arthropod).
It's the other way around. Senses - sight, hearing, smell, taste, touch - react to things and changes in the environment.
sensory perception
Arthropod means "jointed feet" and includes arachnids, crustaceans, insects, and others. What they would use for shelter varies too greatly to list here and would be based on the environment of the specific arthropod.
