They are the largest marine phylum in terms of species count, containing about 23% of all the named marine organisms. [267] Molluscs have more varied forms than other invertebrate phyla. They are highly diverse, not just in size and in anatomical structure, but also in behaviour and in habitat.
The whale shark is the largest species in this order, reaching up to 20 meters long when fully mature. [50] No other species in the order even approaches this size. The next largest species is the nurse shark (Ginglymostoma cirratum), which can grow up to 4.3 m (14 ft) across the disk and weighing more than 350 kg (770 lb). [51] Sawfish ...
