Chaetomorpha - Chaetomorpha

Japanese: ジュズモ(数珠藻) - ジュズモ(英語表記)Chaetomorpha
Chaetomorpha - Chaetomorpha
A seaweed of the family Cladophoraceae in the order Euphorbiaceae. The algae are thread-like, unbranched, and have rhizoids. The cells are large, and the filaments have a rough texture like a row of string beads. Several species are known in Japan, but on the Pacific coast, C. spiralis and C. crassa in particular grow in the lower intertidal zone below the low tide line, and are often found among washed-up algae, as they are wrapped around various other seaweeds. The former is highly curled like a strongly twisted thread, while the latter is softer than the former and often forms large clumps. C. moniligena , a member of the same genus, grows in the upper intertidal zone, and although its bodies grow upright and in clumps, they do not form clumps. The upper cells are swollen and spherical.

緑藻類ミドリゲ目シオグサ科の海藻。藻体は糸状で分枝せず仮根をもっている。細胞は大型で糸状体はじゅず玉が並んだようなあらい感じがする。日本では数種知られているが,太平洋側では特にフトジュズモ C. spiralis,ホソジュズモ C. crassaが潮間帯の下部から低潮線下に生じ,他のいろいろな海藻に巻きついているので,打上げられた藻類の間に発見されることが多い。前者はよりの強い糸のようによくちぢれており,後者は前者に比して軟らかくしばしば大きな塊になる。また,同属のタマジュズモ C. moniligenaは,潮間帯の上部に生ずるが,体は直立して叢生するが団塊にはならない。上部の細胞はふくれて球状を呈している。
