Appearance
"Valonia ventricosa" typically grow individually, but in rare cases they can grow in groups.
Habitat
They appear in tidal zones of tropical and subtropical areas, like the Caribbean, north through Florida, south to Brazil, and in the Indo-Pacific. Overall, they inhabit virtually every ocean throughout the world, often living in coral rubble.The greatest depth for viability has been seen as approximately 80 metres.
Reproduction
The single-cell organism has forms ranging from spherical to ovoid, and the color varies from grass green to dark green, although in water they may appear to be silver, teal, or even blackish. This is determined by the quantity of chloroplasts of the specimen. The surface of the cell shines like glass. The thallus consists of a thin-walled, tough, multinucleate cell with a diameter that ranges typically from 1 to 4 centimetres although it may achieve a diameter of up to 5.1 centimetres in rarer cases. The "bubble" alga is attached by rhizoids to the substrate fibers.Reproduction occurs by segregative cell division, where the multinucleate mother cell makes daughter cells, and individual rhizoids form new bubbles, which become separate from the mother cell.
