Using the short-lived turquoise killifish, a transparent in vivo reporter line named klara is established that will be a valuable tool to explore development, senescence, aging, and regeneration.
Rapid and efficient CRISPR/Cas9-mediated knock-in of fluorescent reporters at various genomic loci enables cell- and tissue-specific expression and establishes the short-lived African killifish as a vertebrate system for precise genetic engineering at scale.
A novel in vivo strategy for reversible, multiplexed control of circulating hormone expression levels, achieved by combining genome-editing and intramuscular electroporation of fluorescently tagged hormones in the naturally short-lived turquoise killifish.
An automated feeding system to precisely control feeding in the killifish opens new areas to explore vertebrate lifespan, cognitive decline, dietary interventions, and drug screening in a high-throughput manner.
The turquoise killifish from ephemeral pools in African savannah combines extremely short lifespan with a standard vertebrate body plan – ideal attributes for a laboratory animal.

Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.
