the eyes are located in the center of its head so it is probebly adapted to walking on the sea floor as well as swimming
Natural Selection :D
Yes, they have crystal eyes.
If the eyes were located toward the front of the head,the organism was probably an active swimmer.If the eyes were in the back of the head, the organism might have been an ocean bottom dweller. in most species,the eyes were located midway on the head-ideal for an organism that both crawled on the seafloor and swam in the water.

Trilobites with flat eyes lived above the surface of the ocean floor, those with stalks burrowed below it. Those with very large or no eyes may have lived in lightless depths; those with all-round vision may have been prey, while those with binocular vision may have been predators. Just like animals living today, really.
A phacops fossil is the preserved remains or trace of an extinct genus of trilobite, a group of marine arthropods that lived during the Paleozoic era. These fossils are typically found in ancient marine sediments and are characterized by their distinctive appearance, with segmented bodies, compound eyes, and a hard exoskeleton.
Trilobite+sand=crab
rock and plankton
Although researching has provided a definition for the word trilobite there does not seem to be any reference as to why one would be referred to as a trilobite. A trilobite is an extinct arthropod from Paleozoic times of which the skeleton is divided into three parts.
The colossal squid (Mesonychoteuthis hamiltoni) has the largest eyes of any known animal, reaching up to 11 inches (28 cm) in diameter. Their eyes are believed to be the largest among all invertebrates.
