* "Insect" is a specific category: It refers to a particular class of animals within the phylum Arthropoda. There's no single category that encompasses everything else.
* Opposites are relative: The opposite of "insect" depends on what aspect you're focusing on.
Here are some examples of what you might mean by "opposite of insect" and possible word choices:
By classification:
* Vertebrate: This refers to animals with a backbone, like mammals, birds, fish, reptiles, and amphibians. This is a broad category, but encompasses a large portion of animals that are not insects.
* Arachnid: This refers to a class of arthropods that includes spiders, scorpions, mites, and ticks. They are closely related to insects but have distinct characteristics.
By characteristics:
* Non-arthropods: This encompasses all animals that don't have jointed legs and a hard exoskeleton, like worms, mollusks, and mammals.
* Larger: Insects are typically small. The opposite could be "large animal" or "macrofauna".
