• On October 12. 2017, the third issue, second year, (28 pages) of Killi-Data News has been published and sent to all active members as a PDF. [please note that a detailed analysis of Freyhof's clarifying post-molecular work on Aphanius anatoliae group leads (1) to accept, in Killi-Data, iconii, fontinalis and meridionalis as revalidated species with (some) molecular differences (not obvious for fontinalis) and with importantly new clear diagnoses of live males (vs. all other components of that group), (2) to accept anatoliae, splendens, sureyanus, and transgrediens as distinct species (not subspecies anymore), but (3) NOT to accept maeandricus and saldae as distinct species because of lack of new diagnoses for them and because of some ambiguity on conservation issues vs. systematics on saldae/splendens (however further studies are needed and this position may be changed in the future -further way or back-, like amways in systematics). Aquarium populations have been reallocated to newly defined accepted as valid species [Jean Huber].

  • On June 19. 2017, Nibia Berois, Graciela Garcia, and Rafael Omar de Sa have a new paper ready to be published by Developmental Dynamics, rather unusual because it is not new research output, but because it synthesizes all known modern data on annual killifish worldwide based on 2 International Symposia (2010 and 2015) that took place in Montevideo and an international book last year (article title : A global Community Effort to decipher the unique Biology of annual killifish). It is freely available online at http://onlinelibrary.wiley.com/doi/10.1002/dvdy.24533/epdf and it is written in an easy language then everybody should read it right away and… hats-off to this great interdisciplinary initiative stemmed from USA, Czech Republic, Italy, Brazil, Chile and Uruguay.
  • On June 1. 2017, the second issue, second year, (18 pages) of Killi-Data News has been published and sent to all active members as a PDF. The big news in this issue is the paper from the Reznick lab. The contents of that paper goes to the heart of the question of just what a killifish is. The phylogenies from Reznick et al. may fundamentally transform our understanding of the origin and evolutive timing of Cyprinodontiformes (including killifish). There are 3 articles on the embryonic development of South American Annual fish : Austrofundulus, Austrolebias and Millerichthys. Martin & Podrabsky review the concept of developmental arrest and define the terms diapause, delayed hatching etc. as well as review the knowledge of diapause learned from Austrofundulus [excerpted from editorial by Tyrone Genade].

  • On September 22. 2016, surprising finding, according to Hundt et al. (2016), contrary to morphological data, there is substantial molecular evidence for 4 species in the Fundulus catenatus superspecies with F. bifax and F. stellifer in the Mobile Basin, F. catenatus in the Tennessee River and its tributaries, and an undescribed (and un-named) species, F. sp. cf. catenatus, present across the rest of the range (the short branches at the base of the cytb tree may indicate that the four taxa rapidly diverged).
  • On July 31. 2016, the second issue (22 pages) of Killi-Data News has been published and sent to all active members as a PDF. This Summer issue contains all output of research and evidence-based information available on killifish, published since first (Spring) issue in April.

  • On December 10. 2015, Killi-Data reports on 2 international large "connected" teams who sequentially publish, in the same famous magazine Cell, important findings about the genome of Nothobranchius furzeri, the fish with shortest lifespan, including a sex-differentiating chromosome and a link between diapause, lifespan and genome (localized in male chromosome)… yes 2 major breakthroughs since the sex differentiation is seen within the genome, not like previously in karyotype morphology (e.g., in Megupsilon aporus) (very technical reading, beware !).
  • The last full update of the database for members-only on November 24. 2015 includes 1447 Killiflash (vs. 1318 in February 2015, 1139 in May 2014 and 735 in September 2013), 1502 taxa (generic or specific level) (vs. resp. 1489, 1472 and 1455), 2881 photos (vs. 2836, 2781 and 2705), 180 maps (vs. 176 in September 2013), 5167 bibliographic references (vs. 5039, 4952 and 4871), 8409 collecting localities (vs. 8315, 8248 and 8209), 2 killiaquar.

  • On November 3. 2015, a new major scientific book (and a must buy) is announced on annuals (see all details in members' section… hurry up to order).
  • On October 31. 2015, exactly the 1000th valid species of killifish has been described as Rivulus mabura (actually it is part of a batch of 3 new species in the same magazine but historically this is indeed mabura, named in Laimosemion that hits the symbolic number ! (parallely the official FACEBOOK page is still climbing with 1046 likes after having crushed the target of 1000 likes early this month, with the full text of this alert and… many statistical numbers where Wilson Costa is by far on the lead while the total number of taxa, including generic names and synonyms, reaches 1500).
  • Previous alerts in this page are to be read at INDEX-ARCHIVES.
  • The "guest" section is fully open and anonymous (no e-mail needed to enter) and it is fully updated with automatic programmes and a list of alerts (brand new latest publications) plus their inventories at FLASH-ARCHIVES
  • The "members" section is strictly payable after REGISTRATION (no more free granting for any person, contributor or not) : it remains easily affordable (6 Euro, i.e. about 7 US$, for a full year after permanent membership) and it is considerably enriched with new pages and with an automated updating process.
  • The "members" section mainly contains the database and all killiflash since 1961 (all major publications on killifish with reference, abstract and short analysis for each) : to freely check the contents of the database, please read the SAMPLE page, or if you intend to write an article, ask for a GRATUITY page of a given name of killifish.
  • The "guest" section holds a lot of advertising (please readily click on links if interested) : this is aimed to cover the costs of IT development programmes each year so that all fees from "members" are redistributed to young researchers and to aquarists-collectors for their first trip.
  • This is not any more, at the generic level, a mirror of current research (it became too unstable since 2009) but an objective analysis of current knowledge, in order to avoid too numerous name changes without added value and without stability sake ; but this only concerns the generic level, while the species level is, as usual, automatically derived from latest published evidence (beware, that strategy is different from listing various published results and/or published opinions to compare them without deciding).
  • In total, the principles of the project are maintained (data quality and financial redistribution) even if, because the project is not a single person project any more, it may only be living in the long run by data contributions from all members.




Communication and cooperation free services:

A new version of the website has been made available early 2012, and for the guest section, browsing is slightly different from the previous version (started in 2001) :

This is not any more a single person project (although the initial author Jean Huber is still pivotal) and the whole project has been nested within a non-profit association named Killi-Data International, or K-D-I (see there all details for past and new members).

Mission statement

legend  Killi-Data aims to present all available information on Killies or oviparous Cyprinodontiformes fishes.
Killi-Data compiles state of the art knowledge, wherever it sources from, scientist or aquarist.
Killi-Data is evidence based, not opinion based. If conflicting results arise from distinct phylogenetic methods, then a compromise is selected that purports the maximum of results, ending up in a splitting way if stability is not treatened.
Killi-Data is a non-profit venture that redistributes all financial benefits, the major part being attributed to young scientists or collectors to support research on oviparous Cyprinodontiformes fishes or Killies.
Killi-Data strongly encourages cooperation between ichthyologists, either professional or amateur, and aquarists to build a cooperative community of interest and knowledge.
