The meaning of AMPHIBLASTULA is a free-swimming larva of certain sponges that is essentially a blastula with small flagellated cells in one hemisphere and large nonflagellated cells in the other.

, Oscarella), called an amphiblastula, is oval in shape and has a cavity in the middle; the front half of the larva consists of cylindrical, flagellated cells, the other half of round cells without flagella. The larva swims with the flagellated portion forward.

2025年1月13日 · In the amphiblastula, the choanocytes are derived from the forward flagellated region; the other cells and the mesohyl are derived from the posterior half. Choanocytes create the water currents through sponges and capture food particles.

There are two general types of sponge larvae, solid parenchymella larvae and hollow amphiblastula larvae. Sizes range from 50 pm to 5 mm in length. Differential pigmentation of the posterior or anterior pole is not unusual and commonly coincides with areas lacking cilia.

The below mentioned article provides a diagram of amphiblastula (larva). 1. It is a free swimming larval stage of Sycon and many other calcareous sponges. 2. The body is some what ovoid in form and is comprised of an anterior half of small flagellated micromere cells and a posterior half of large non-flagellated macromere cells. 3.

Amphiblastula larva is a typical free swimming larva formed in Sycon sponge reproduction. 1. It is ova! in shape. 2. It shows small micromeres with flagella on one side. 3. The other half of the larva shows large macromeres. 4. The larva comes out of the sponge through osculum. 5. It swims in the water for some time with the help of flagella.

Amphiblastula: It is a hollow, oval type larval stage that is seen in many calcareous sponges like Scypha. Anterior one-half of amphiblastula bears flagella, where the posterior half does not. Parenchymula: It is a solid, oval, or flattened larval stage. It is characteristic of only a few calcareous sponges like the deep-water Monaxonellid Sponge.
