Seven tachykinin-related peptides (from OctTKRP-I to OctTKRP-VII) were isolated from the Octopus vulgaris.17 Finally, a type of tachykinin-related peptide receptor (TKRPR) was isolated from the bivalve Anodonta cygnea, and more recently, a novel TKRPR from the cephalopods Octopus vulgaris has been described.17, The cDNA of preproOctTK-I and preproOctTK-II are very similar.17,32 OctTKs were included in the sequences flanked by a typical dibasic signal at the N-terminal and an amidation signal and a single basic residue at the C-terminal. Here the blood is collected and goes to the gills.� Then it ends up at the auricles of the Living near the sediment surface can lead to dislodgment, thus a number of riverine unionoidean taxa have shell and pedal morphologies adapted for rapid reburial (Watters, 1994a).

The Asian clam Corbicula fluminea is a problematic invasive species in aquatic ecosystems and can impair the survival of parasitic larvae (glochidia) of native freshwater mussels. This pattern of asymmetrical sex allocation in functional hermaphrodites could be a response to a variable intensity of sperm competition. Although all these creatures are widely diverse, they possess one feature in common: they possess rather low innate mobility, which probably made them convenient for use in experiments in the first place.
