We found a karyotype of 46 chromosomes made up of 8 metacentric, 12 submetacentric, and 26 acrocentric elements (FN = 66). No heteromorphic sex chromosomes were observed in the species. Metacentric chromosomes were easily classified as homologous pairs according to their morphology and L/S ratio. The rest of the chromosomes could not be accurately classified as homologous pairs because differences in chromosome size and L/S ratio were too slight between adjacent pairs within a size-ranged series. A single pair of NOR-bearing chromosomes was found. Active NORs were terminally located in a submetacentric pair of chromosomes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Conventional karyotype and nucleolar organiser regions of the toadfish <i>Halobatrachus didactylus</i> (Schneider, 1801) (Pisces: Batrachoididae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:08.328067","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Toadfish; NOR","Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2020-09-08","DateCreate":"2004-01-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000187353600007","VABBcode":null,"OpenAcc":1,"DOI":"10.3989/scimar.2003.67n4445"},"refs":null,"anarec":{"AnaID":56541,"PubliDate":2003,"Pagination":"445-449","XtraPublOfAnaID":null,"ISBN":null,"Volume":"67","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43791,"SerRR":"Scientia Marina (Barcelona).
