Meaning and Definition
A specific larval stage in the development of certain sponges, characterized by a hollow ball of cells with two distinct types of cells.
In marine biology and embryology, the amphiblastula is a free-swimming larval form of calcareous sponges (class Calcarea) that precedes settlement and metamorphosis into the adult sponge. It is a key stage in understanding sponge reproduction and development.

FAQ
Frequently Asked Questions
No, despite the 'amphi-' prefix, it is not related to amphibians. The prefix here refers to the two (amphi) different types of cells that characterize this sponge larva.
It is found specifically in certain sponges, primarily within the class Calcarea (calcareous sponges).
Typically no. Amphiblastulae are microscopic or just barely visible as tiny specks, requiring a microscope for detailed study.
Its main function is dispersal. The free-swimming amphiblastula larva allows the sessile (non-moving) sponge species to colonise new areas before settling and transforming into the adult form.

Mnemonic
Think: 'AMPHI' (both or two) + 'BLAST' (germ or bud) + 'ULA' (small). A small bud with two cell types.
Conceptual Metaphor
None in common use. In technical contexts, it might be described as a 'swimming blueprint' for the adult sponge.
