https://www.al-museum.com/ • Japanese commentary is followed by English commentary • This BGM was generated by CINESCORE. • 中心はやや硬く、周縁は柔らかく透明なアメーバ。滑る動きで偽足は目立たない。体の後ろから食物を吐き出す。細胞内に様々な顆粒を蓄え、滑る動きに伴い体内に入れていく。珪藻が入りそうになるが逃げ去った。 • ---- 月井雄二先生(法政大)のコメント ---- • これは有殻アメーバの一種，コクリオポディウム（Cochliopodium）です。 • http://protist.i.hosei.ac.jp/PDB/Imag... • 皿を逆さにしたような殻があるのですが，薄く透明なので通常の観察ではわかりません。 • 細胞が基質から離れて浮遊し，横向きになると，その殻を観察することができます。 • 例： • http://protist.i.hosei.ac.jp/PDB/Imag... • An amoeba is gliding smoothly across the glass slide under the microscope. The rim of its body is transparent, but the center of its body is filled with food and slightly rigid. Although it doesn't extend pseudopods, food particles enter its body as the amoeba moves over them. A diatom is temporalily captured, but manages to escape. • ---- Commentary by Prof. Yuji Tsukii, Hosei University ---- • This organism is a species of testate amoeba called Cochliopodium. • http://protist.i.hosei.ac.jp/PDB/Imag... • The shell of this organism is like an upside-down plate, but as the shell is thin and transparent, its exact shape is difficult to see in ordinary observation. • When the organism detaches from the surface to float freely, the side view and shell shape become visible • http://protist.i.hosei.ac.jp/PDB/Imag...
