English Dictionary

cassiosome

名詞

A stinging-cell structure, composed of a layer of mainly nematocytes surrounding a core of dinoflagellates, amoebocytes and mesoglea, expelled within mucus by Rhizostomeae jellyfish to sting (and in some cases kill) prey in the surrounding water.

日本語の意味

刺胞構造：クラゲ（特にRhizostomeae）によって、主に刺胞細胞からなる一層で取り囲まれた、双鞭毛藻、アメーバ様細胞、中胚葉を含む中心部分が、粘液中に排出され、周囲の獲物を刺す（場合によっては殺す）ための細胞構造。

During the tide pool survey, researchers photographed a cassiosome surrounded by shimmering mucus as it drifted toward its prey.

潮だまりの調査中、研究者たちは獲物に向かって漂う、渦鞭目のクラゲが粘液中に放出した刺胞構造（主にネマトサイトの層が渦鞭藻、アメーボサイト、メソゲレアの中心部を取り囲んでいる）を撮影した。

意味（1）

A stinging-cell structure, composed of a layer of mainly nematocytes surrounding a core of dinoflagellates, amoebocytes and mesoglea, expelled within mucus by Rhizostomeae jellyfish to sting (and in some cases kill) prey in the surrounding water.

Released within the mucus, we discovered three types of undeployed nematocysts, as well as microscopic, motile, cellular masses composed of nematocytes that we formally call cassiosomes. While cassiosomes bear some resemblance to another cnidarian structure originating in mesenteries of the starlet sea anemone Nematostella called nematosomes, the unique traits of cassiosomes in C. xamachana include their release into the water column within mucus, the ability to trap and kill prey as mobile grenades outside of the medusa, their organization as an outer epithelial layer surrounding a mostly empty core (rather than a solid ball of cells), and the presence of centrally-located endosymbiotic Symbiodinium dinoflagellates.
