Nanoaechaeum equitans is the archea specie with the smallest genome length. Its genome is so short that this microorganism needs another organism to live: Iggniococcus hospitalis. Then, it is an epibiont. Its evolutionary interest is due to the fact that we can study the minimum viable genomes in addition to its survival in extremophile environments…
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…
Atlantic horseshoe crab
Limulus polyphemus, the Atlantic horseshoe crab, is a marine arthropod considered a “living fossil” extending back approximately 450 million years. The blood color is blue due to the presence of hemocyanin and contains amoebocytes, used to detect toxins. Its genome presents specific duplications of genes related to innate immunity. https://doi.org/10.1186/2047-217X-3-9, 05/14/2014 Author: Guillem Dachs Margarit
Myxococcus xanthus
Myxococcus xanthus is a social eubacterial predator that exhibits various forms of self-organizing behavior in response to environmental cues. Its genome offers unparalleled access to a regulatory network that controls development and that organizes cell movement on surfaces. DOI: 10.1073/pnas.0607335103 (December/19/2006) Author: Carolina Doñate Alarcón
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…
Wasp spider
The wasp spider is a large orb-weaving spider with striking colors, freaturing black and white bands on a yellow abdomen. Females are much larger than males. It is commonly found in meadows, fields and along roadsides throughout Europe. It builds large circular webs that include a zig-zag shaped band called stabilimentum, whose function is still…
S. solfataricus
Saccharolobus solfataricus is an archaeal species that thrives in volcanic environments with high temperatures and acidity. It serves as a model organism for studying DNA replication, the cell cycle, chromosomal integration, transcription, RNA processing, and translation. 10.1073/pnas.141222098 (Jun 26, 2001) Author: Mar Iglesias Navarrete
D. radiodurans
Deinococcus radiodurans is the most radiation resistant organism. Its genome sequencing aids in understanding extreme radiation resistance and enhancing bioremediation applications. 10.1126/science.286.5444.1571 (Nov 19, 1999) Author: Vera Alfaro Tena
Pyrolobus fumarii
Pyrolobus fumarii is a hyperthermophilic chemolithoautotroph known as the primary producer of organic matter at deep-sea hydrothermal vents. Its genome sequencing provides insights into early life evolution and extremophile adaptations. Author: Elena Jiménez
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…
