Ray

While all rays are flat, not all flatfish are rays. Rays have gill openings on the undersides, where their mouth is located. Sharks do not have any of these things. The order to which rays belong, called "Batoidei", contains 534 species. Batoidei also includes sharks and skates. The most well-known type of ray is the stingray, which gets this name from its venomous barbs located on the top side near its head. In addition to being a fast swimmer and having good vision, stingrays also have a sixth sense called "ampullae of Lorenzini", which helps them find prey in muddy or dark waters. Rays and sharks belong to the same class (Chondrichthyes). Rays, like many other types of fish, reproduce in a way that involves external fertilization: male and female meet, have sex, release their eggs and sperm into the water to mix with one another, and the resulting product is an egg, which hatches into a larva. The two main types of rays are skates and sawfish. Skates' eggs hatch internally (ovoviviparity), while the eggs of sawfish develop in the female before birth (viviparity). With ovoviviparity there is no placental link, so the eggs grow in the oviduct of the female and hatch into miniature versions of their parents. With viviparity, there is a placental link to nourish the young inside their mother's uterus. There are about 534 species of ray alive today. Most rays live on or near the bottom of the ocean, where they are camouflaged. When an object nears them, the rays can swiftly swim away to avoid it. Rays have good eyesight, which helps them find prey in murky waters. The stingray is a type of ray that gets its name from its venomous barbs located on the top side near its head. In addition to being a fast swimmer and having good vision, stingrays also have a sixth sense called "ampullae of Lorenzini", which helps them find prey in muddy or dark waters. A typical ray has five-gill openings on its underside where water is drawn into its mouth. Most rays can swim backward because their bodies are so flexible that they can squeeze backward through tight places. Manta rays feed mostly on plankton and smaller organisms that live in the water column. Mantas may be curious, but they are not aggressive towards humans, and will generally swim away if approached by a diver.

Global ray production

Ray fish is a popular seafood item around the world, and their numbers are kept stable through aquaculture. In 2010, the top ray fish-producing countries were China, India, Thailand, and Vietnam. Combined, these countries produced over 1.5 million metric tons of ray fish. The global production of ray fish has remained relatively stable in recent years, fluctuating between 1.4 and 1.6 million metric tons. Ray fish are commonly consumed in Asian countries, where they are often cooked with rice or noodles. In China, ray fish is considered to be a delicacy, and is often served on special occasions. In Vietnam, ray fish is often made into a soup called canh chua cá lóc, which is served with rice and vegetables. The United States is the largest importer of ray fish, importing over 300,000 metric tons in 2010. The vast majority of these imports come from China, India, and Vietnam. The United States also exports ray fish, though the volume is much smaller, at around 10,000 metric tons.
