Subject: placozoans biol. Пожалуйста, помогите перевести.Слово встречается в следующем контексте: Because sponges lack neurons, and both cnidarians and ctenophores have them, this new hypothesis throws an interesting wrench into our understanding of the early evolution of the NS: either neurons evolved twice, convergently, or neurons arose once and were subsequently lost in sponges and placozoans (Ryan, 2013).
