| Throughout the euphausiids, decapods, and stomatopods, larvae invariably possess compound eyes, which are naturally complicated structures. |
| A similar dispersal mechanism has been suggested as responsible for the faunal similarities in mollusks and decapods. |
| Plankton such as euphausiids are important food for pre-grisle but amphipods and decapods are also consumed. |
| By any measure, decapods are underrepresented in the fossil record by comparison with organisms with more heavily calcified exoskeletons. |
| The calcified cuticle of decapods comprises the hard exoskeleton of the animal and can be subdivided into four layers. |
| Urine signals, excreted through nephropores located near the base of the antennae, are a likely source of pheromonal cues in decapods. |
