In addition, she classified Farfantepenaeus into two groups according to the shape and position of the rostrum with respect to the segments and flagellum of the antennule
and the ratio RL/CL: 1) F.
sports thousands of hairlike odor sensors, which give the lobster an extraordinarily sensitive sense of smell by which to navigate.
proximal article more than 3x as long as wide, article 2 not longer than article 3.
The sixth stage has a segmented inner flagellum of the antennule
and fully developed pleopods with setae.
In the presence of certain amino acids, the neurons of the antennule
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.
Olfactory responses of lobsters (Homarus americanus) to solutions from prey species and to seawater extracts and chemical fractions of fish muscle and effects of antennule
Manganese accumulation by the antennule
of the Norway lobster Nephrops norvegicus (L.
As a consequence of the fouling of antennules
, olfactory setae (responsible for chemically mediated perception of food and mates) can be damaged, possibly leading to the interruption of distance hemoreception (Bauer, 1989).
The sympod on the antennules
of adult males was characterized development of soft sensory setae (see both species, after attaining size 6.
