Dasycladales are unicellular algae that can grow to a length of 200 mm. They may have been even larger in past geological times. This is an incredible size for a unicell. Multicellular organisms gain stability by constructing walls of differentiated cells to demarcate their several functional elements, while some of the huge unicellular organisms gain stability by surrounding themselves with a calcareous coating. This is how the long unicellular Dasycladales gain enough stability to grow upright. When a calcified alga dies the coating may be preserved in the sediment as an impression of a once-living structure. Consequently, fossils of these coated algae exist, sometimes in great numbers, over relatively long periods of time. One of these long-enduring groups is the algal order called Dasycladales. It had already been in existence a long time at the dawn of the Cambrian period, about 570 million years ago. The fact that the Dasycladales have survived for so long a time with but few changes in distinctive features has lad many to call them "living fossils". Five families with nearly 200 genera, some with a large number of species, have evolved but most have become extinct. They flourished in the Middle Permian, the Early Jurassic, at the Jurassic/Cretaceous boundary and during the Palaeocene. In the Holocene new genera developed which, together with the genus Acetabularia that originated in earliest Oligocene times and some persistent Cretaceous genera, constitute the present-day representatives of the Order Dasycladales. It comprises two families, the Dasycladaceae and Polyphysaceae, with 10 genera and 38 species. Some genera are represented by only one or two species, and some species are rarely observed today.

The order Dasycladales of the green algae includes macroalgae which grow in the shallow waters of tropical and subtropical shores as far north as the Mediterranean Sea. They are rarely found in deep water but have been observed to a depth of 20 m.<p> Dasycladales are now classified as members of the Class Ulvophyceae (Graham & Wilcox, 2000), although van den Hoek et al. (1993), due to their unique combination of features, placed them in a discrete class, the Dasycladophyceae.
