Aphyosemion photographs added
Thanks to long-term member Bob Merritt we have expanded our photographic library with over 60 photos of this large genus, many of the species being rare to see these days. Attendees at previous Conventions will recall seeing Bob’s stunning photographs displayed at the back of the lecture room. These digital copies don’t quite have the same impact but the spectacular range of colours and vibrancy of the genus are still captured beautifully. Available to view exclusively on this website and…
Attenborough’s Killifish
Discovered over 20 years ago but only recently described by science. Nothobranchius attenboroughi could become a flagshipspecies for the epic landscape of the Serengeti.

New description and a new species of Nothobranchius
Redescription of the seasonal killifish species Nothobranchius ocellatus and description of a related new species Nothobranchius matanduensis, from eastern Tanzania (Teleostei: Nothobranchiidae) Brian R. Watters, Béla Nagy, Pieter D. W. van der Merwe, Fenton P. D. Cotterill and Dirk U. Bellstedt* Ichthyological Exploration of Freshwaters/IEF-1149/pp. 1-28 Published 26 June 2020 LSID: http://zoobank.org/urn:lsid:zoobank.org:pub:7E606C25-EDD9-4D05-81E3-B368688851CE DOI: http://doi.org/10.23788/IEF-1149 The description of Nothobranchius ocellatus was based on a unique holotype, comprising an immature male, and a photograph of a female. The holotype is apparently lost….

Sex ratios deviate across killifish species without clear links to life history
Will Sowersby, Alejandro Gonzalez-Voyer & Björn Rogell Evolutionary Ecology – volume 34, pages411–426(2020) Abstract Sex ratios can differ from an expected equal proportion of males and females, carrying substantial implications for our understanding of how mating systems evolve. Typically, macro-evolutionary studies have been conducted without assessing how deviations from an equal sex ratio could be explained by sex-biased mortality or dispersal. Our understanding of sex ratio evolution independent of these confounds, in addition to any putative links between skewed sex ratios and other factors…
