Final answer:
Animals like scallops and cubozoans have eyes on either side of their head, providing a broad field of vision for environmental awareness and hunting. Opabinia, an extinct creature, also had multiple eyes, indicating the diversity of eye placement in the animal kingdom.
Step-by-step explanation:
Animals with eyes on either side of their head are typically known for having a wide field of vision that aids in their environmental awareness and self-defense. For instance, the remarkable scallops possess a unique mantle where conspicuous eyes are located in clusters; these eyes include a cornea, lens, and retina resembling true organs. Similarly, the mysterious cubozoans, or box jellies, are outfitted with four clusters of eyes that have image-forming capabilities, despite their lack of a distinct brain. These biological adaptations help such creatures to thrive in their respective environments, whether through scanning for predators or hunting for prey.
