This study was designed to examine the biochemical basis of lipid alterations in liver, kidney, and intestine of sea lamprey, Petromyzon marinus, during their nontrophic metamorphosis. Lipolysis, as indicated by triacylglycerol lipase (TGL) activity, increased in liver from larva to stage 6 and in k

In larval sea lampreys (Petromyzon marinus), a small, relatively inconspicuous olfactory organ sac contains small, densely packed olfactory receptor neurons and sustentacular cells. During metamorphosis, the larval organ transforms into a prominent lamellar structure with large distinct olfactory ep

## Abstract The ultrastructure of the trunk lateral line nerve of larval and adult lampreys was studied with transmission electron microscopy. We confirmed that lampreys' lateral line nerve lacks myelin. Nevertheless, all axons were wrapped by Schwann cell processes. In the larval nerve, gaps betwe
