Doliolum is a genus of small, transparent, spherical marine animals called radiolarians. Radiolarians are a type of protozoan that are characterized by their calcium carbonate skeletons and unique ability to produce silica shells.
I apologize, but the word "doline" is not a commonly used word in English language. However, after researching, I found that a "doline" is a noun that refers to a depression or hollow in the ground, typically formed by erosion or weathering. It can also refer to a small valley or a dent in a surface.
A doliolid is a type of free-swimming, predatory marine animal, specifically a pelagic tunicate. It is a gelatinous, soft-bodied animal that belongs to the phylum Tunicata. Dolioles are characterized by their long, slender bodies and their ability to propel themselves through the water using a unique type of propulsion called "jet propulsion." They are found in oceans around the world and play an important role in the marine ecosystem as both predators and prey.
