Nothobranchius furzeri, the turquoise killifish, is a species of killifish from the family Nothobranchiidae native to Africa where it is only known from Zimbabwe and Mozambique. This annual killifish inhabits ephemeral pools in semi-arid areas with scarce and erratic precipitations and have adapted to the routine drying of their environment by evolving desiccation-resistant eggs that can remain dormant in the dry mud for one and maybe more years by entering into diapause. Due to very short duration of the rain season, the natural lifespan of these animals is limited to a few months and their captive lifespan is likewise short, mak... [more]

The sea lamprey is a member of an ancient lineage that diverged from the vertebrate stem approximately 550 million years ago (MYA). By virtue of this deep evolutionary perspective, lamprey has served as a critical model for understanding the evolution of several conserved and derived features that are relevant to broad fields of biology and biomedicine. Studies have used lampreys to provide perspective on the evolution of developmental pathways that define vertebrate embryogenesis, vertebrate nervous and neuroendocrine systems, genome structure, immunity, clotting and others. These studies reveal aspects of vertebrate biology that have bee... [more]
