Over 8,000 creative name suggestions were gathered via social media platforms. After careful consideration, the research team decided on the name Ferreiraella populi, with "populi" being a Latin term that translates to "of the people." Notably, 11 individuals independently proposed this same name during the online campaign.
A Journey from YouTube to Scientific Recognition
The public naming initiative was inspired by Ze Frank, who showcased this unusual deep-sea chiton from the Ferreiraella genus in an episode of his "True Facts" series on YouTube.
This fascinating creature features eight protective shell plates and a robust radula, which serves as its tongue. Additionally, it is home to a small group of worms that thrive on its waste. Viewers were encouraged to submit potential scientific names along with their reasoning, resulting in an impressive response of over 8,000 entries within just one week.
Prof. Dr. Julia Sigwart, co-chair of SOSA at the Senckenberg Research Institute and Natural History Museum Frankfurt, expressed her excitement: "We were amazed by the enthusiastic response and the plethora of imaginative name suggestions! The name Ferreiraella populi reflects a connection to the public."
Several other names also caught attention during the selection phase. One notable suggestion was Ferreiraella stellacadens, meaning "Shooting star chiton," inspired by the creature's unique aesthetic and rapid rise to fame. Another name, Ferreiraella ohmu, referenced a chiton-like entity from a Studio Ghibli film, paying homage to Japan, where the species was discovered.
An Exceptional Specialist of the Ocean Depths
The species was initially discovered in 2024 within the Izu-Ogasawara Trench, at a staggering depth of 5,500 meters. Ferreiraella populi belongs to a rare group of mollusks that exclusively inhabit sunken wood in the deep sea.
This finding contributes to the understanding of chitons, a group that has not received much scientific scrutiny, and supports the growing evidence that deep-sea wood-fall ecosystems host highly specialized communities that remain largely unexplored, according to Sigwart.
Chitons are often likened to a combination of snails and beetles. Unlike most mollusks that possess a single shell, chitons are equipped with eight distinct shell plates, enabling them to curl into a protective ball or adhere tightly to uneven surfaces such as sunken wood. They inhabit a variety of environments, from shallow coastal areas and coral reefs to the deep ocean, with some species thriving at depths of up to 7,000 meters in complete darkness.
The Process of Naming New Species
Upon discovering a new species, it is assigned a formal scientific name as part of its original taxonomic classification. This naming system adheres to Carl Linnaeus's principle of binomial nomenclature, comprising two components: the genus name (the first part, capitalized and italicized) and the specific epithet (the second part, lowercase and italicized). The name is designated by the authors who publish the initial scientific description and must comply with international regulations such as the ICZN (for zoology) or the ICN (for botany). Each name must be unique, Latinized, and previously unused, often drawing inspiration from physical characteristics, geographical locations, mythology, or individuals honored for their contributions.
The Importance of Timeliness in Ocean Biodiversity
The case of Ferreiraella populi underscores the immense biodiversity present in our oceans, much of which remains uncharted. Numerous species vanish before scientists even recognize their existence, a challenge particularly evident among marine invertebrates, highlights Sigwart.
"The process of studying, scientifically describing, naming, and publishing a new species can often take a decade or even two. At SOSA, we are committed to expediting these processes while actively involving the public with these captivating creatures. Collaborating on a name for the chiton through social media has been a fantastic opportunity to do just that! Ferreiraella populi has been scientifically named merely two years after its discovery, which is vital for the conservation of marine diversity, especially given the threats it faces, such as deep-sea mining!"
