Molluscs like cephalopods and gastropods dominate the marine world. Inhabiting nearly every ecosystem from shallow reefs to deep sea vents and the pelagic midwater, the success of molluscs is unparalleled. Nearly 25% of all marine organisms are molluscs, including such oddities as sea snails, nudibranchs, and coleoids like squid with their specialised tentacles. Even the snails you might find in your garden belong to the molluscs, for this is the only phylum with species found in the sea, freshwater and on land. A testament to their adaptability. With an estimated 85,000 living species known to science, the abundance and diversity of molluscs is what allows them to occupy a great many niches and habitats, and diversify into an assortment of shapes and sizes. The smallest meiofauna molluscs grow to just 0.4 mm long, while in the pelagic deep they dominate as voracious predators, looming out of the dark. This is the alien world of molluscs.

I do not own any of the footage. I write the script, narrate, and edit what footage I can find. Footage used belongs to the incredible marine conservation societies of Schmidt Ocean Institute, NOAA, MBARI, WHOI and the Ocean Exploration Institute, along with various other YouTube sources.
