Abstract:
Rostral pores are epidermal invaginations which occur on the internarial region of most chelonians. Representatives of all Recent chelonian families and 67 of the 74 extant genera were examined grossly and/or histologically. Pores are absent only in the families Carettochelyidae, Cheloniidae, and Dermochelyidae. The number and microscopic structure of pores vary markedly within and between taxa. Morphological data suggest that rostral pores could function in mechanoreception. The possible origin and evolution of rostral pores are discussed in the context of other chelonian integumentary speializations.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...
