 | | Maxilliped 1 has no gills but has the important epipod that encloses the exhalant water channel and the gill bailer. | | | The first three segments of the decapod thorax are fused with the head to form a cephalothorax and their appendages are maxillipeds. | | | It is common in crustaceans for the head to fuse with some anterior thoracic segments to form a new tagma, the cephalothorax. |

| | Anterior and Posterior: a position: (relates to the body) anterior indicates that an appendage is located near the head end of the body as opposed to the rear end of the body (the posterior). | | | Medial: a position: usually the inside face of an article (that facing the body). | | | Maxilliped: A pair of appendages situated posterior to the maxillae and derived from the first pair of thoracic appendages. |

| | Crabs were considered conscious if they were responsive to stimuli applied to the eyestalks and the third maxillipeds; these responses determine if the cerebral and thoracic ganglia, respectively, are still functioning. | | | Injection with Euthasol caused a short period of distress (15-30 seconds) followed by loss of both the maxilliped and ocular responses, suggesting unconsciousness, until death. | | | The crabs retained their ocular and maxilliped reactions for most of this time, suggesting retention of consciousness. |

| | In those Crustacea which have no such free fold but a cephalothoracic shield covering the cephalon and part or the whole of the thorax, this shield was interpreted as a carapace fold fused to the dorsum of the thorax and often overhanging its sides, for example, in lobsters and natantians. | | | The carapace hypothesis has been universally accepted and has influenced the interpretation of Crustacean evolution and inter-relationships. | | | In the Anaspidacea, Amphipoda and Isopoda, which have no branchiostegal folds behind the maxilliped segment, the external segmentation is retained in all segments behind it, and the same is the case with the segments behind the cephalothoracic shield in, for example, mysids and cumaceans. |

| | Hydrodynamic sensors of the maxilliped are likely to be utilized when captured food particles have to be manipulated for ingestion or rejection. | | | It was the goal of our study to determine the structures of potential sensors of setae on appendages of calanoids which are involved in the collection of food particles after these have been perceived at a distance from the gathering appendage(s). | | | Our results indicate that all setae of the female's maxilliped possess structures indicative of mechano- and chemosensors. |
