Abstract Many types of suspension-feeding plankton larvae produce one or more, up to 1 cm long mucous strings. These function as drift anchors by increasing hydrodynamic drag. This effect, together with gravitational forces, allows the larvae to remain almost motionless relative to the undisturbed water column while feeding. Larvae that are essentially

Publisher Summary This chapter focuses on the larval stage of insect lifecycle. The term “larva” is used for all immatures that are not eggs, pupae, or adults. When larva is used in this comprehensive sense, the subcategories include exopterygote larva, for Hemimetabola, which have the wingpads developing externally, and endopterygote larva, for ...

Molluscan Larvae: Pelagic Juveniles or Slowly Metamorphosing Larvae?
The Biological Bulletin, 2009Asking the right questions about evolution of development, larval morphology, and life history requires knowledge of ancestral state. Two hypotheses dominate current opinion about the ancestral life cycle of bilaterians: the "larva-first" and the "intercalation" hypotheses. Until recently, the larva-first hypothesis was preeminent.
