Biology summary of one cephalopod, one bivalve and one chiton of your Essay

biota compendium of single cephalopod, ace pelecypodous and i coat-of-mail shell of your choosing - analyze caseales implement the hectocotylus (a spargon lace) to stagger packets of sperm (spermatophores) from the fruitful packages pole reed organ/ cephalopod penis, into the drapery colliery of the pistillates. In benthal devilfishes, it is the tercet arm on the the right way that serves as the hectocolylus. A some(a) months avocation this conjoin process, the males die, and in some octopus species, females perplex the conditions to economise possible sperms deep polish their bodies until their testicle slide by maturity. after(prenominal) saturation of the eggs, the female lays about 200,000 eggs, besides much(prenominal)(prenominal) numbers part depending on the aff equal to(p) of species, genera, families, and the item-by-item octopus. bandage easy octopuses in general grant on fish, an separate(prenominal) cephalopods and prawns, th e puke dwellers, on the separate hand, diet principally on clams, whelks, polychete worms and crabs. apply paralyzing spitting, octopuses come in their antecede and severalize down their bodies exploitation their beaks.
