Oral Fimbriae and Papillae in Parasitic Lampreys (Petromyzontiformes)

  title={Oral Fimbriae and Papillae in Parasitic Lampreys (Petromyzontiformes)},
  author={K. Teresa Khidir and Claude B Renaud},
  journal={Environmental Biology of Fishes},
There are 38 species of living lampreys, 18 parasitic and 20 nonparasitic. The parasitic species feed as adults, while the nonparasitic do not. The taxonomy and systematics of the living lampreys is based primarily on dentition characters. Since the number of oral fimbriae and oral papillae have never been systematically investigated in lampreys, we compared them in 17 of the 18 parasitic lampreys to assess their usefulness as taxonomic characters. Both showed little variation with total length… Expand

The evolutionary ecology of lampreys (Petromyzontiformes)
It is argued that at least some paired species of lampreys do not comprise two distinct evolutionary lineages; rather, that non-parasitic lampreys represent one extreme in a continuum of life history variation expressed by a parasitic species. Expand
The Use of Gill Pore Papillae in the Taxonomy of Lampreys
The structures within the gill pore of lampreys are shown to be a new taxonomic character that provides a method of improving the interpretation of speciation in lampreys, particularly for nonparasitic species. Expand
Lethenteron ninae, a new nonparasitic lamprey species from the north-eastern Black Sea basin (Petromyzontiformes: Petromyzontidae)
Lethenteron ninae sp. n., a nonparasitic lamprey, is described from rivers of western Transcaucasia in Russia and Abkhazia. It is distinguished from the other species of Lampetrinae in Europe andExpand
Sensory cutaneous papillae in the sea lamprey (Petromyzon marinus L.): I. Neuroanatomy and physiology
It is shown that sea lampreys have cutaneous papillae located around the oral disk, nostril, gill pores, and on the dorsal fins and that SCCs are particularly numerous on these papilae and these results provide new insights on the function and evolution of the SCC system in vertebrates. Expand
Morphometric and physical characteristics distinguishing adult Patagonian lamprey, Geotria macrostoma from the pouched lamprey, Geotria australis
The aim of this study was to determine morphometric and physical characteristics of adult G. macrostoma that further differentiate this re-instated species of Geotriidae from G. australis. Expand
Post-metamorphic Feeding in Lampreys
Eighteen of 41 lamprey species worldwide feed post metamorphosis; nine in either marine waters or fresh waters and nine exclusively in fresh waters. Four feeding modes have been identified: bloodExpand
At-sea feeding ecology of parasitic lampreys
To unlock understanding of the marine phase of anadromous lampreys, direct evidence of feeding ecology should be coupled with natural and artificial markers to identify habitat use, movement patterns and dispersal. Expand
On an unknown lamprey holotype (Petromyzon macrostomus Burmeister 1868) and the genus Exomegas Gill 1883 from South America.
Preliminary results resolve a century-long taxonomic uncertainty and foster a nomenclatural arrangement for a Southern Hemisphere lamprey genus. Expand
Feeding in Jawless Fishes
This chapter demonstrates how hagfish and lamprey generate true biting movements and provides a comprehensive review of the anatomy and biomechanics of jawless feeding in both taxa. Expand
Phylogeny of the lamprey genus Lethenteron Creaser and Hubbs 1922 and closely related genera using the mitochondrial cytochrome b gene and nuclear gene introns
This chapter discusses the phylogenetic status of the genus Lethenteron, which includes Lampreys and satellite species, and Mitochondrial cyt b gene and nuclear gene introns, as well as other aspects of mitochondrial function. Expand


A proposal for the functional and phylogenetic significance of differences in the dentition of lampreys (Agnatha: Petromyzontiformes)
It is concluded that blood-feeding preceded flesh-feeding in ‘modern’ lampreys; endemic freshwater parasitic species typically ingest blood; the ability to feed on flesh developed in populations which had access to estuarine and marine hosts; and pre-Tertiary forms resembling contemporary lehthyomyzon unicuspsis could have given rise independently to both of the divergent and specialized genera of Southern Hemisphere lampreys.

A new parasitic species of the holarctic lamprey genus Entosphenus Gill,1862 (Petromyzonidae) from Klamath River,in California and Oregon.
A new parasitic lamprey is described from 29 metamorphosed specimens in feeding stage and is easily separable by its functional intestinal tract and strong dentition from the three nonparasitic species: Entosphenus folletti, E. hubbsi, and E. lethophagus. Expand
Satellite species among the holarctic lampreys (Petromyzonidae)
Among the six polyspecific genera of the holarctic lampreys, 12 parasitic and 20 satellite species are presently known. Expand
Conservation status of Northern Hemisphere lampreys (Petromyzontidae)
Among the 34 nominal lamprey species in the Northern Hemisphere, ten are endangered; nine are vulnerable at least in part of their range, and one is extinct. The major cause is habitat degradationExpand
Comments on the Classification and Nomenclature of Lampreys — An Alternative View
It is suggested that modern lampreys be classified in one family, three subfamilies, and six genera, and most species are in a single genus Lampetra consisting of six subgenera. Expand
