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.

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
Atlantic puffin
Fratercula arctica, the atlantic puffin, is an iconic seabird species, important for tourism, and inherently valuable for the marine ecosystem. Its genome includes thousands of loci that help identify relevant conservation units for seabirds. https://doi.org/10.1038/s42003-021-02415-4 (July/29/2021) Authors: Aina Baldomà Fort, Javier Cordero Plaza, Maria Donés Guillamet, Julia Íñiguez Sanz
Bactrian camel
Camelus bactrianus, the Bactrian camel, has two humps where they can store energy in the form of fat, allowing them to survive long periods without food or water. Its genome also reveals genes with resistance insulin functions. https://www.nature.com/articles/ncomms2192 (November/13/2012) Authors: Júlia Bou Vallès, Laia Xin Mercadé Pelfort, Ivett Moro Rodríguez, Paula Valero Delgado
Great white shark
Carcharodon carcharias, the great white shark has a high capacity to heal wounds, a key factor in its lifespan of 73 years. Its genome reveals molecular adaptations and positive selection of key genes involved in wound healing. 10.1073/pnas.1819778116 Author: Oscar Santamaria
