Oysters are also known for their ability to produce natural pearls. Mussels have this ability to produce pearls as well, however, it is rare for them to do so.
Oysters vs Mussels
The difference between oysters and mussels is that oysters have rough, dull, and hard shells that are covered in barnacles while mussels have smooth, purplish-black shells that are oblong shaped and have elongated ends.
The shell of an oyster is generally oval-shaped. While its inner surface tends to be white in colour, its outer surface may be dark grey, white, blue, purple, or brown.

What are Oysters?
Oysters are bivalve mollusks that mostly live under marine water but are sometimes found in rivers and seas as well. Their oval-shaped shells are hard, rough, and covered in barnacles.
Oysters have been a food option for people since prehistoric times. Their cultivation is known to have begun from the times of the imperio Romano. At present time, they are considered a delicacy for their wide range of flavor profiles and rich nutrient content.
The fertilization of oysters takes place internally. They self-fertilize and produce millions of eggs in about six hours only. These eggs develop into larvae that attach to a host for survival. Subsequently, they find a permanent habitat for themselves where they can fully mature.
Oysters have many varieties and species. Interestingly, their taste depends on the environment that they live in. Some of the edible varieties of oysters include European flat, Pacific Oyster, Olympia Oyster, Kumamoto, Dredge Oyster, Rock Oyster, etc.

What are Mussels?
Mussels are edible bivalve mollusks that are commonly found in brackish water. They have smooth shells that are oblong shaped and elongated ends. The color of their shells tends to be purplish, black, or brown.
Mussels commonly grow up as males and end up turning into females. The fertilization of these shellfish takes place externally. Mussel eggs turn into larvae and attach themselves to the fins and gills of other fish. When they grow up, they tend to live in symbiotic colonies in which they depend on each other to survive.
Mussels fix themselves to rocks and other surfaces using threads which are referred to as ‘byssal’ threads. These threads are known to have great strength. At present, scientists are even trying to develop an adhesive from mussels to be used during eye cirugía.
There are about 17 species of mussels that are fit for human consumption. Some of the edible varieties of mussels include Blue Mussels, California Mussels, Mediterranean Mussels, Pinna Carnea, Perna Perna, etc.
