ABSTRACT
Garstang, Walter The Amphiblastula is notable as a larval pioneer Who disregarded all maxims of development each year: Half flagellate, Half amoeboid, he takes his silent plunge, Adheres, and tucks his front end in, to build a baby Sponge. Why does the Amphiblastula do things the wrong way round, When hinder poles are recognized as vegetative ground? The Parenchymula is worse, for he turns inside out, His dermal cells being all inside, his gastral all without!
