The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs. The human mitochondrial genome (mitogenome), for example, comprises ...
Accomplishing perhaps a world first, researchers at Columbia University and the Marine Biological Laboratory (MBL) have mapped the full-body muscular activity of an animal while it was moving and behaving.
The tube-dwelling anemone is an ancient sea creature that resembles a prehistoric flower. The animals live slow, long and predictable lifestyles and look fairly similar from species to species.
Comparative genome content analyses provide insight into the early evolution of animals. A novel method that permits the use of larger datasets in such studies yields results that are consistent with classical views of animal ...
Jellyfish undergo an amazing metamorphosis, from tiny polyps growing on the seafloor to swimming medusae with stinging tentacles. This shape-shifting has served them well, shepherding jellyfish through more than 500 million ...
Researchers from the Stowers Institute for Medical Research have opened a window on another piece of evolutionary biology. They have found that Hox genes, which are key regulators of the way the bodies of bilaterally symmetrical ...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, ...
Despite its apparent simplicity, a tube-like body topped with tentacles, the sea anemone is actually a highly complex creature. Scientists from the Institut Pasteur, in collaboration with the CNRS, have just discovered over ...
Mucus is able to protect us from infection thanks to ancient genes that have been conserved throughout 350 million years of evolution—dating back to our days as a jellyfish.
During embryonic development, genetic cascades control gene activity and cell differentiation. In a new publication of the journal PNAS, the team of Ulrich Technau of the Department of Molecular Evolution and Development ...
