英文/音标中文/解释

1	sponge [spʌndʒ]	海绵
	Porous multicell organism, mostly marine (currently about 5,000 species); it anchors itself to a support and filters water to take in food particles. 多孔的多细胞有机体，主要是海洋生物（目前约5000种）；它将自己固定在一个支架上，过滤水以吸收食物颗
2	anatomy of a sponge	海绵解剖

3	pinacocyte	扁平细胞
	Flat ectodermal cell forming the outer covering of the sponge. 形成海绵外层的扁平外胚层细胞。
4	spongocoel	[动]海绵腔
	Hollow portion of the sponge covered with choanocytes, in which water circulates before exiting through the osculum. 海绵的中空部分，上面覆盖有软骨细胞，水在其中循环，然后通过卵丘流出。
5	mesohyl	中质
	Gelatinous substance, rich in water, located between the ectoderm and the endoderm. 胶状物质，富含水，位于外胚层和内胚层之间。
6	endoderm [’endoʊˌdɜːm]	内胚叶;内胚层
	Inner layer of the sponge formed of cells (choanocytes) whose role is mainly to feed the organism. 海绵的内层，由细胞（软骨细胞）构成，其作用主要是喂养有机体。
7	ectoderm [’ektəˌdɜːm]	外胚层
	Outer layer of the sponge formed of cells (pinacocytes) whose role is mainly to protect the organism. 海绵外层由细胞（松果体细胞）构成，其作用主要是保护有机体。
8	incurrent pore	入水孔
	Opening into the gastric cavity, through which water enters the sponge. 进入胃腔，水通过胃腔进入海绵。
9	osculum [’ɒskjʊləm]	排水孔;吸附器官;吸盘
	Large opening protected by spicules, through which the sponge discharges water from the gastric cavity. 由针状物保护的大开口，海绵通过它从胃部排出水。
10	water flow	水流; 水流,径流
	Choanocyte flagella allow water to move inside the sponge, carrying oxygen and food particles to it. 软骨细胞鞭毛允许水在海绵内移动，携带氧气和食物颗粒。
11	choanocyte [koʊ’ænəˌsaɪt]	环细胞
	Inner cell having a filament (flagellum), which allows water to circulate and food particles to be caught and digested. 有丝（鞭毛）的内部细胞，允许水循环，食物颗粒被捕获和消化。
12	calcareous sponge	钙质海绵纲
	Marine sponge with a skeleton composed of small calcareous needles (spicules). 海生海绵，骨架由小的钙质针（针状物）组成。
