Scale bars = 35 mm (a), 90 mm (b), and 1 mm (c–f). At the brain level, lampreys and hagfishes have remarkable differences but also many similarities. In contrast to amphioxus (a cephalochordate), they have a number of special sense organs that convey information over the cranial...
A switch from unidirectionally ventilated to tidally ventilated gills after metamorphosis allows parasitic lampreys to breath while attached to fish during feeding. The gills and kidneys are also restructured, taking up and retaining Na + and Cl 鈭 in dilute freshwaters, but excreting these ions ...
Many fish survive the attacks, however, and Lake Superior fish caught by anglers often have circular marks where lampreys were attached. Sea lampreys are by far the most destructive of all aquatic invasive species to hit the Great Lakes. Native to the Atlantic Ocean and the St. Lawrence Ri...
despite that they belong to separate biological classification groups entirely. Lampray is a good source of vitamin A. It is not a raised fish meaning all sources of lampray is taken from nature often found attached to the bodies of trout and salmon caught commercially or for recreational ...
These phylogenetic insights also suggest that the last common ancestor of hagfishes and lampreys was a macrophagous predator that did not have a filter-feeding larval phase. Thus, the armoured ‘ostracoderms’ that populate the cyclostome and gnathostome stems might serve as better proxies than...

Previously, we investigated parapinopsin as a vertebrate non-visual opsin model to obtain a clue to relevance of the molecular properties of a non-visual opsin to its physiological functions11,12,13,14,15,16. We found that parapinopsin, which is first found in catfish pineal and parapineal...
(Mateus et al.2012). The sea lamprey is highly valued as a food fish where populations are large enough to be exploited (Quintella2006), so commercial overfishing is a serious threat for the species in areas such as the Iberian Peninsula (Mateus et al.2012) and elsewhere in Europe (...
The presence of lampreys on a fish did not further the incidence of attack on that fish. None of the species of fish appeared to avoid lamprey attacks, nor did they avoid fish on which lampreys were attached. Only rarely were fish observed to dislodge lampreys....
When retrieving commercially valuable fish from Lake Huron with juvenile sea lamprey attached, fishers remove the sea lamprey and fasten plastic numbered tags to them with brass wire and store them in a 20 L pail with formaldehyde solution for preservation. Recorded data include tag number, capture...
