#Balanomorpha is a clade of #barnacles of the higher taxon#Cirripedia.As adults these #crustaceans are #sessile with a calcareous #shell to fully retract, secreted by the pouch-like, modified carapax. M.Zhang et al. (2023) isolated the #mitochondrialgenome of the invasive species Megabalanus coccopoma,thus establishing it as a #scientificmodel.

#Beach gooseneck #barnacles find.
There's 3 different types of barnacles found in BC waters/on beaches - acorn, gooseneck & whale - the latter grows on whales' bodies. Barnacles are a longtime, year-round staple #seafood for coastal #Indigenous #FirstNations. In particular, the #Haida & #Kwakwakawakw & #Pacheedaht #FirstPeoples have several documented stories involving barnacles, including food prep recorded histories.
Barnacles are #ancient and can be dated to the middle of Cambrian period of Paleozoic because of Burgess Shale deposits in #BritishColumbia. They're #hermaphroditic #MarineAnimals.
