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…
Lowland anoa
Bubalus depressicornis, the lowland anoa, is a wild dwarf buffalo endemic to Indonesia. Its genome provides evolutionary data on wild species of the genus Bubalus, as well as information on the similarities and differences between them and domestic species. https://doi.org/10.1093/g3journal/jkac234 September/16/2022 Authors: Rubén Lorenzo Martínez, Luna Lozano Sanchez, Carla Martin Rodriguez, Lara Martínez De la…
Blue whale
Balaenoptera musculus, the blue whale, is the largest animal known to have ever existed. Its genome sequencing aids in understanding marine mammal biology, longevity, and resistance to cancer. 10.1093/molbev/msae036 (Feb 20, 2024) Authors: Berta Poch Ordoñez, Cynthia Ramírez Arias, Daniel Robledillo Manotas, Gracia del Pilar Sánchez López
Western gorilla
Western gorilla (Gorilla gorilla) is a species of primate in the family Hominidae (great apes). The reference sequence is from the fibroblast of a male and mature gorilla. The size of the genome is of 3500 Mb, the number of coding genes are 22365 and they have 24 chromosomes. The article where the genome of…
Cozumel Harvest Mouse
Cozumel Harvest Mouse (Reithrodontomys spectabilis) is assessed as Critically Endangered because this species is known only from Cozumel Island, Mexico where it is estimated to exist in small subpopulations (< 50 individuals/subpopulation) with an estimate of less than 200 individuals in the entire population. The species has not recovered from negative impacts from introduced species…
Ridgway’s Hawk
Ridgway’s Hawk (Buteo ridgwayi) is listed as Critically Endangered because it has a small and fragmented population, which was previously in steep decline. Successful conservation action has now reversed such declines and the species is observed to be increasing throughout both its largest extant population in Los Haitises National Park and additional reintroduced populations. If…
Jico Deer Mouse
Jico Deer Mouse (Habromys simulatus) is listed as Critically Endangered because it is known from only two subpopulations: one is likely now extinct, and the other has extremely low population numbers (less than or equal to 50). Most of the mature individuals from are in one subpopulation. If more habitat continues to disappear, this species…
Galapagos Penguin
Long-term monitoring of the Galapagos Penguin (Spheniscus mendiculus) indicates that the population is fluctuating, primarily as a result of marine perturbations that may be becoming more extreme through climate change. These perturbations have caused an overall very rapid population reduction over the last three generations (31 years). In addition, the species has a small population…
