Aquila chrysaetos, the golden eagle, is a monogamous bird that, even though its grand size, can fly up to 300 km/h, therefore represents a symbol of strength. Its genome reveals evidence for a unique vision system biased towards ultraviolet vision. DOI: 10.1371/journal.pone.0095599.

Genomic interest areas: Extinction risk
Brown bear
Brown bears can enter a metabolic state similar to hibernation even outside the cave, and their genome reveals genes associated with the ability to “switch off” processes such as muscle degradation and bone loss. This makes them a fascinating biological model for studying human diseases such as osteoporosis or muscle atrophy, as they spend months…
Black-footed cat
The black-footed cat is the tiniest feline in Africa, and one of the smallest in the world, measuring about 40 cm, with an impressive body weight of 1.9 kg. Unlike most felines, they’re poor climbers, instead they dig in the sand to take refuge in burrows. The black-footed cat is endemic to the arid grasslands…
Komodo dragon
Varanus komodoensis, the Komodo dragon, is the largest living lizard, capable of taking down prey much larger than itself. Its genome reveals adaptations for a powerful cardiovascular system, heightened metabolism, and a robust immune response, resembling traits typically seen in mammals. DOI: 10.1038/s41559-019-0945-8 Author: Asier Otal
Snow leopard
Panthera uncia, the snow leopard, is a solitary and elusive big cat adapted to cold mountainous regions, with thick fur, powerful limbs, and a long tail that aids in balance. Its genome reveals adaptations to high-altitude environments, such as genes related to oxygen transport and energy metabolism, as well as evolutionary links to other big…
Mexican Wolf
Canis lupus baileyi, the Mexican gray wolf, is the smallest subspecies of the gray wolf, known for its mottled coat, social pack behavior, and role as a top predator in its ecosystem. Its genome reveals low genetic diversity due to a severe population bottleneck, but also contains unique adaptations that reflect its historical range and…
Giant manta
The Mobula birostris is the largest species of ray in the world, reaching up to 7 meters wide—yet it feeds on tiny plankton filtered through its gills! These gentle giants can even leap out of the water, a behavior scientists still don’t fully understand. DOI: 10.1038/s41586-021-03451-0 Author: Anna Landabaso
Aldabra giant tortoise
Aldabrachelys gigantea, the Aldabra giant tortoise, is one of the longest-lived terrestrial vertebrates, with lifespans over 150 years. It can survive months without food or water by storing nutrients and slowing its metabolism. Its genome offers insights into longevity, gigantism, and resilience in extreme conditions.

Bengal Tiger
There are some tigers who do not have the characteristic orange skin. Instead, they have white skin due to a mutation in the SLC45A2 gene. This mutation reduces the production of pheomelanin (the yellow or orange pigment in their fur) but retains some eumelanin (the black pigment), which forms their distinctive dark stripes. 10.1093/gigascience/giac112 (12/28/2022)…
Leopard
Panthera pardus, the leopard, has a spot pattern unique to each individual, akin to human fingerprints. Its genome reveals adaptations that allow it to live in a wide variety of habitats. DOI: 10.1093/gbe/evac128, Publication date: August/17/2022 Authors: Judith Agel Gelis, Mattin Arana Lopetegi, Arnau Crehueras Getan, Leia Tomàs Puig
