Ref..   Hardisty, M.W. 1986
  Remark
:
Distribution: Mainly north hemisphere temperate zones of the world.
Size; larvae max 10 cm, adults max 120 cm.
Habitat and ecology: Marine species anadromous. Parasitic or non-parasitic, the latter restricted to freshwater. Land-locked, lake populations or species are common in the northern hemisphere, which also commonly appear as species pairs, with one species parasitic, and the other non-parasitic.
The larval (ammocoete) stage is filter feeding, whereas the adult uses the sucker shaped mouth to attach to other fishes and feeds off the wound (feed on a variety of bony fishes, right whale Eubalaena glacialis, sharks like Cetorhinus maximus, Prionace glauca, Carcharhinus plumbeus, C. obscurus, Somniosus microcephalus Ref. 58185).
Description: Jawless vertebrates with cartilaginous skeleton and notochord. Eel-like in shape; scales and paired fins absent; adults with well developed eyes; pouch-like gills not supported by gill arches; corneous teeth on the circular oral disk and the tongue; dorsal and ventral nerve roots separated; nasohypophyseal sac has an external opening only; intestinal tract with spiral valve and cilia; members of Petromyzontinae have the highest number of chromosomes (164-174) among vertebrates; 1 (genus Ichthyomyzon) or 2 (all other genera) dorsal fins; cloaca under the anterior half of the second dorsal fin; midgut of ammocoetes (at least in Entosphenus tridentatus, Lampetra fluviatilis, and Petromyzon marinus) does not possess a diverticulum; oral papillae present along the anterior and lateral edges of the oral disc, but absent from the posterior edge; all oral papillae of uniform size; oral fimbriae present around the entire perimeter of the oral disc; one supraoral lamina; labial teeth either pointed or rounded; eyes dorsolateral in immature and mature adults; fins separate in immature adults and contiguous in mature adults of genera with 2 dorsal fins; second dorsal fin/posterior lobe of the single dorsal fin confluent with (= continuous with) the caudal fin in ammocoetes as well as in immature and mature adults; one pair of kidney-shaped buccal glands; gular pouch, when present, small, never extending past the posterior edge of the eye.
Reproduction: Sexes separate; eggs numerous (thousands), small and not yolky, buried in spawning redds excavated in clean, hard bottoms (litophilous broodhiders). Non-parasitic species breed immediately after metamorphosis. Parents die after spawning. The larval (ammocoetes) stage lives for several years in freshwater before undergoing a radical metamorphosis and then as a rule returns to the sea.
Lampreys (together with hagfishes) are the most basal extant vertebrates. Definite fossil records date back to the upper Carboniferous, about 280 million years ago (Ref. 12268). Also from the Cretaceous of China from 125 million years ago and from the Devonian of South Africa from 360 million years ago.
Ammocoetes and adults are used as bait in some areas. A number of species are used as food.
Classification: The classification follows Ref. 89241 based on partial results of Ref. 89370 where Geotria and Mordacia are separated in two other distinct families (Ref. 89241, Ref. 58010). Hence the meaning of the subfamily Petromyzontinae is consequently changed.
Petromyzontidae Petromyzontinae ((Petromyzon, 1 sp., Ichthyomyzon, 6 spp.) Lampetrinae (4 gen., 29 spp.) Geotriidae (Geotria, 1 sp.) Mordaciidae (Mordacia, 3 spp.)

Species/Synonymy list for the family Petromyzontidae as currently in FishBase

Important recommendation:

The list below must not be used as an authority reference synonymy list like those found in scientific published revisions, which must be the source to be used and cited eventually when they exist.

Rather, it reflects the current content of FishBase, and the progress with respect to synchronization with the Catalog of Fishes. However, we think it can be useful for users to assess the quality of information in FishBase, to start new work on the family, or to cross-check with other lists.

But we appreciate to be cited in publications when this list has been of any working value. In particular, for published scientific, we suggest then to cite it in the Material and Method section as a useful tool to conduct the research, but again, not as a taxonomic or nomenclatural authority reference.

Unless it is explicitly precised, the list is not complete, please search all original names published for the family in the Catalog of Fishes (genera, species), including those with uncertain or unknown status, that are not included in FishBase when they are not attached to a valid species.

This list uses some data from Catalog of Fishes (not shown but used to sort names).

In the column CofF, the digit indicates the status of synchronization with CofF: 0: Not checked; 1: Same status;   2: Different status;   3: Other combination;   4: Synonym in CofF;   5: Species/Subspecies issue;   6: Synonym of another species in CofF;   7: Not in CofF;   8: Should not be in CofF. The CofF version currently used is the one published on 23-07-2014 (Ref. 97102).

The list ordered as follows:

Please send comments and corrections if you detect errors or missing names.
