The Prussian carp (Carassius gibelio) has one of the most unusual genomes in the animal kingdom—some populations reproduce asexually through a process called gynogenesis, where the sperm from a male of another species is needed to trigger egg development, but the sperm’s DNA is not incorporated into the offspring. As a result, some individuals are…
Class: Actinopteri
European eel
Its body is covered in a slimy mucus layer and its coloration ranges from olive-brown to yellowish on the belly. They live in freshwater but migrate to the sea to spawn. Specifically, they are born in the Sargasso Sea, then drift thousands of kilometers across the ocean to European rivers, where they spend most of…
Clown anemonefish
The false clownfish, Amphiprion ocellaris, is a popular fish species and an emerging model organism for studying the ecology, evolution, adaptation, and developmental biology of reef fishes. The false clownfish, Amphiprion ocellaris, shows different agonistic behaviours, defined as an individual’s aggressive behavior towards a conspecific, living with different host anemones. Juvenile fish were exposed to…
Atlantic salmon
Salmo salar, the Atlantic salmon, is a migratory fish species found in the North Atlantic Ocean and its tributaries. Its genome sequencing aids in understanding salmon genetics, aquaculture, and conservation. 10.1038/nature17164 (Apr 18, 2016)
Torafugu
Takifugu rubripes, the Japanese pufferfish, is a model organism in genetics and genomics research. Its genome sequencing aids in understanding vertebrate evolution, comparative genomics, and human disease modeling. 10.1126/science.1072104 (Aug 23, 2002)
Zebrafish
Danio rerio, the zebrafish, is a popular model organism in scientific research due to its rapid development and transparent embryos. Its genome sequencing aids in studying vertebrate development and genetics. 10.1038/nature12111 (Apr 17, 2013)
Japanese grenadier anchovy
Coilia nasus, a migratory fish, has a genome that informs us about its ecological adaptations and population dynamics. 10.1093/gigascience/giz157 (Jan 2, 2020)
