IngliżPoorly developed fins, dorsal fins in contact in mature adults, blue-green back, yellow flanks, white ventral portion (Ref. 2163). Diagnostic features: Adults: 8.6-17.0 cm TL. Body proportions, as percentage of TL (based on 16 specimens measuring 10.6-13.3 cm TL): prebranchial length, 10.9-12.6; branchial length, 7.5-9.9; trunk length, 44.4-53.3; tail length, 25.4-31.4; eye length, 2.3-2.9; disc length, 5.2-7.0. Urogenital papilla length, as a percentage of branchial length, in ten spawning males measuring 11.1-14.0 cm TL, 21.4-52.6. Trunk myomeres, 60-65. Dentition: supraoral lamina, 2 unicuspid teeth; infraoral lamina, 7-9 teeth, usually all unicuspid, but occasionally one lateralmost bicuspid; 3 endolaterals on each side; endolateral formula, typically 2-3-2; 2 rows of anterials; first row of anterials, 9 unicuspid teeth; exolaterals absent; posterials absent; transverse lingual lamina, 9-13 unicuspid teeth, the median one enlarged; longitudinal lingual laminae each with about 9 unicuspid teeth. Velar tentacles, 4-6, with tubercles. Body coloration (preserved), dorsal and lateral aspects grayish, ventral surface whitish, dorsal fins and caudal fin yellowish. Some specimens display a prominent dark blotch at the apex of the second dorsal fin. The iris is yellow. Lateral line neuromasts unpigmented. Unpigmented caudal fin except for spawning individuals in which it is "weakly peppered". Caudal fin shape, spade-like (Ref. 89241). Sigmund Freud (Ref. 72450, 72451 ) described the development of the central nervous system of brook lamprey.

MaltiXewk ma tantx żviluppati, xewk gangliji f'kuntatt fl-adulti matur, blu-aħdar lura, isfar ġnub, porzjon bridges abjad (Ref. 2163). Karatteristiċi dijanjostiċi: adulti: 8.6-17.0 ċm TL. Il-ġisem ta ' proporzjonijiet, bħala perċentwali ta ' TL (ibbażat fuq kampjuni 16 tal-kejl ta ' TL 10.6-13.3 ċm): tul tal-prebranchial, 10.9-12.6; it-tul branchial, 7.5-9.9; it-tul tal-ġisem, 44.4-53.3; it-tul tad-denb, 25.4-31.4; it-tul ta ' l-għajnejn, 2.3-2.9; it-tul tad-diska, 5.2-7.0. Tul urogenital papilla, bħala perċentwali tal-tul branchial, fl-għaxar irġiel bajd TL 11.1-14.0 ċm, 21.4-52.6 tal-kejl. Trunk myomeres, 60-65. Snien: supraoral lamina, snien 2 unicuspid; infraoral lamina, 7-9 snien, is-soltu kollha unicuspid, imma kultant wieħed lateralmost bicuspid; endolaterals 3 fuq kull naħa; il-formola endolateral, tipikament 2-3-2; 2 ir-ringieli ta ' anterials; ewwel filliera ta anterials, snien unicuspid 9; exolaterals assenti; posterials assenti; lamina muskolu trasversali, snien unicuspid 9-13, il-medjan wieħed imkabbra; lonġitudinali muskolu laminae kull bi snien unicuspid madwar 9. Tentacles velari, 4-6, mal-tubercles. Korp kolorazzjoni (preservati), aspetti laterali u dorsali grayish, bridges wiċċ abjad, gangliji xewk u denb safranija. Xi kampjuni juri li blotch fid-dlam prominenti fil-quċċata tat-tieni gangliji tad-denb. L-iris huwa isfar. Neuromasts linja laterali unpigmented. Unpigmented denb ħlief għal ibejjed individwi li dan huwa `dgħajjef peppered`. Denb forma, bħat-qlugh (Ref. 89241). Sigmund Freud (Ref. 72450, 72451) deskritti l-iżvilupp tas-sistema nervuża ċentrali ta brook lamprey.
