Dendritically branched branchiae occur in the posterior setigers.
To add contrast to external structures, such as parapodia, branchiae, and papillae, the specimens were dyed with methyl green, Rose Bengal and an aqueous solution of methylene blue.
Palps short; about same length as adjacent branchiate and densely ciliated on frontal surface one pair of thick, ciliated branchiae inserted just posterior to palps.
The clefts on the neck in the embryo of man show where the branchiae (60) once existed.
Two achaetous segments follow this ridge, each bearing a lateral pair of lamellate branchiae similar in size (although the first pair are slightly longer than the second pair).
Others concentrate particles in suspension by using their branchiae (polychaetes), their cirri (cirripedes) or their arms (crinoids).
The aquatic species are at greater threat because they are exposed to the chemicals not only through their food chain but also through the contact with their skin or with their branchiae or gills.
Fauchald (1992:284) commented that this species was described on the basis of an illustration and that de Quatrefages (1866:337) referred it to Marphysa; however, the latter author regarded the species as being deprived of branchiae and probably belonging in Lumbrineridae.
Identification of species was based on the morphological characters of rostrum, carapace, branchiae, antennule, antenna, third maxilliped, pereiopods, pleopods, abdomen, telson, petasma, thelycum, and the colored pattern of the whole body based on keys and diagnoses available from the current literature.
The anterior end bears retractable pale green "tentacles," which consist of a pair of grooved palps and branchiae.
