Proteomic analysis of trochophore and veliger larvae
WebIn certain mollusks, the trochophore further modifies into Veliger larvae that are considered as the second larval stage before it fully metamorphosed into an adult. The trochophores are marine planktonic or lecithotrophic larvae comprising of mouth, alimentary canal, and anus. The veliger is the second larval stage in the development of gastropods, following the earlier trochophore stage. In some species, including virtually all pulmonates, the veliger stage is passed within the egg capsule and the hatching stage is a juvenile rather than a free-living larva. In species with a larval stage, the veliger is exclusively aquatic. Free-living veliger larvae typically feed on phytoplankton; however, the larvae of some species are lecithotrophic (nourished by yol… WebThe trochophore develops into a filter feeding, bivalve veliger or D-stage larva of 160 m shell length approximately two days after fertilization (Figure 9). This veliger later develops a foot to become a pediveliger (Figure 10) that alternately swims and rests on the substrate, eventually metamorphosing into a 200 m juvenile clam free online course for cna
