In one study, no behavioural or neural changes in three different crustacean species (red swamp crayfish (Procambarus clarkii), white shrimp (Litopenaeus setiferus) and Palaemonetes sp.) were observed in response to noxious acids or bases.
The shrimp Palaemon serratus of the infraorder Caridea. A shrimp (pl.: shrimp or shrimps ()) is a crustacean (a form of shellfish) with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the order Decapoda, although some crustaceans outside of this order are also referred to as "shrimp".
As most of these shrimp are half transparent, the color of N. davidi nearly always is a result of "blood" ("flesh", muscles etc.) coloration and "skin" (the chitin of the shell) coloration. Some colors may result from a specific mixture of the chromatophores ; xanthophores (yellow/orange), erythrophores (red/orange), iridophores (blue ...
