| Throughout the euphausiids, decapods, and stomatopods, larvae invariably possess compound eyes, which are naturally complicated structures. |
| The rest of the group is sometimes pulled together loosely as the reptant decapods. |
| Urine signals, excreted through nephropores located near the base of the antennae, are a likely source of pheromonal cues in decapods. |
| It is also highly unusual to discover these Paleozoic relics associated with decapods as they normally inhabit different environments. |
| In Japan, decapods associated with coral reef deposits were described in Miocene and Pliocene and Pleistocene rocks. |
| By any measure, decapods are underrepresented in the fossil record by comparison with organisms with more heavily calcified exoskeletons. |
