High impact information on Decapoda (Crustacea)

  • It is more difficult to homologize the isopod serotonin-like immunoreactive neurons with those in the insect CNS, but some stained brain and thoracic neurons share common cell body positions and axon trajectories in isopods, decapods, and insects and may therefore be homologous [1].
  • The decapods (Oedignathus inermis, Pugettia quadridens, Philyra pisum) were distinguished from the other crustaceans (Artemia salina, Bosmina longirostris, Diastylis sp.) by longer sequences (17-41 bp) in the V9 region [2].
  • Decapoda Crustacea molt in order to grow; some species, such as the Dungeness crab Cancer magister, achieve a very large size [3].
  • In decapods, the anterior muscles include conjunctive muscles; these cross the midline and each presumably moves both eyes at the same time during fixation [4].
  • The innervation of the distal and proximal heads of the accessory flexor muscle in three portunid crabs and two non-portunid decapods was studied electrophysiologically [5].

Anatomical context of Decapoda (Crustacea)

  • Since the cells received the stimulus to enter S-phase in vivo, the response must represent one of the mechanisms used by decapods to restore the hemocyte number in the circulation after non-self challenge [6].

Associations of Decapoda (Crustacea) with chemical compounds

  • Moreover, species from the hydrothermal vent decapods from Pacific hydrothermal vent that encounter higher CO2 content in their environment have a higher buffer capacity than Atlantic vent species [7].
  • In recent years, the occurrence of vertebrate steroid hormones, estradiol 17beta (E2) and progesterone (PG) has also been reported in a few decapods, although their precise role in female reproduction is yet to be determined [8].
  • Intertidal decapods regulate their blood glucose with a significant but transitory (60 min) increase upon exposure to atmospheric air, and this has been considered to be an adaptative response related to the almost complete lack of the Pasteur effect in facultative anaerobes [9].
  • Influence of accumulation of cadmium on the content of other microelements of two species of Black Sea decapods [10].
