Input: Read this: In addition, most Grand Lodges require the candidate to declare a belief in a Supreme Being. In a few cases, the candidate may be required to be of a specific religion. The form of Freemasonry most common in Scandinavia (known as the Swedish Rite), for example, accepts only Christians. At the other end of the spectrum, "Liberal" or Continental Freemasonry, exemplified by the Grand Orient de France, does not require a declaration of belief in any deity, and accepts atheists (a cause of discord with the rest of Freemasonry).

Input: Read this: Nearly all polychaetes have parapodia that function as limbs, while other major annelid groups lack them. Parapodia are unjointed paired extensions of the body wall, and their muscles are derived from the circular muscles of the body. They are often supported internally by one or more large, thick chetae. The parapodia of burrowing and tube-dwelling polychaetes are often just ridges whose tips bear hooked chetae. In active crawlers and swimmers the parapodia are often divided into large upper and lower paddles on a very short trunk, and the paddles are generally fringed with chetae and sometimes with cirri (fused bundles of cilia) and gills.
Question: What kind of parapodia do burrowing annelids often have?

Output:
ridges whose tips bear hooked chetae
