About 2,200 species of rotifers have been identified. Contohnya Nematoda (cacing gilik). Bdelloids reproduce through a type of asexual reproduction called parthenogenesis. The study showed that rotifers could withstand the formation of ice crystals during slow freezing. Diploblastic: Ectoderm of the diploblastic animals forms epidermis, nervous tissue and nephridia. 6 Endoderm is the innermost germ layer. Parthenogensis reproduction. Both Rotifera and Nematoda are part of what Phyla? Rotifers can produce hardened cysts (Monogononta) or desiccation-tolerant forms (Bdelloidea), while cladocera and calanoid copepods produce tough resting eggs, that are readily dispersed by water flow, winds, larger organisms and human activity. On the other side of things, they are eaten by creatures such as copepods, fish, jellyfish, and starfish. Such animals are called triploblastic. This means that eggs can develop into embryos without any need for fertilization. Three terms you will not use at all.
