Top Tweets for #OuterShell
#Chitons (#Polyplacophora, #Mollusca) are an #evolutionarily ancient group of mollusks that, as #fossilevidence shows, existed as early as 500 million years ago. Their most striking feature is an #outershell composed of individual #plates; extant species have eight plates, while fossil forms have even more. As in many other animal groups, new, previously unknown species are continually being discovered among the Polyplacophora. #Newspecies can be identified using various species concepts. In the case of Kim, I. & Hwang, U.W. (2026), the new species #Acanthochitona #feroxa was described using #mitochondrialgenome sequences. This species differs morphologically from other species, particularly with regard to its dorsal #spicules and #radulae. This interesting work also provides a comprehensive #phylogenetic analysis, which, for example, determined the age of the genus to have originated in the Late #Cretaceous.

Scientists have uncovered a new species of chiton — a spiky “living fossil” whose body plan has remained largely unchanged for nearly 300 million years.
