VELIGER Meaning and
Definition
-
Veliger is a term commonly used in the field of marine biology to describe a unique larval stage found in certain mollusks, particularly gastropods and bivalves. The veliger stage occurs after the initial embryonic development and precedes the final metamorphosis into the adult form.
At this developmental phase, the veliger possesses distinct characteristics. It typically features a well-developed ciliated velum, a thin, translucent structure that aids in locomotion and feeding. The velum acts as a primary means of propulsion, enabling the veliger to move through water in search of food.
The veliger larvae are typically free-swimming, allowing them to disperse over wider areas and colonize new habitats. During this stage, they often feed on microscopic plankton, utilizing their velum to create water currents that transport food particles towards their mouth. As they grow, veligers undergo a series of morphological changes until they eventually undergo metamorphosis, leading to the development of their adult body plan.
The veliger stage is of particular importance in the life cycle of mollusks as it represents a critical transitional phase between the highly specialized larval form and the mature adult. It provides an opportunity for dispersal and colonization, allowing mollusks to establish populations in different locations. Additionally, the study of veligers plays a crucial role in understanding the ecology and diversity of marine ecosystems, as well as aiding in the management and conservation of mollusk populations.
Common Misspellings for VELIGER
Etymology of VELIGER
The word "veliger" comes from the Latin term "velum" which means "veil" or "sail". It refers to a specific larval stage found in many marine mollusks, such as gastropods and bivalves. The "veliger" larva has a small transparent "veil" or "sail" connected to the head region that serves as a feeding and swimming organ. Hence, the term "veliger" is derived from the Latin word "velum", referring to this distinctive feature of the larva.
