Fine structure of the rectal (salt‐secreting) gland of the spiny dogfish, Squalus acanthias
Abstract The rectal gland of the spiny dogfish, Squalus acanthias has been described by light and electron microscopy. The cell outline shows remarkable complexity in electron micrographs. The basal plasma membrane has numerous complex infoldings and interdigitations separated by groups of mitochond...
