What's in a Name?
Scientists gave the mutton snapper its official name, Lutjanus analis, in 1828. A French scientist named Georges Cuvier first described it. He found the first one in Santo Domingo, which is now in the Dominican Republic. The "analis" part of its name comes from its red, pointy anal fin.
What Does It Look Like?
The mutton snapper has a body shaped a bit like an almond. Its tail fin looks like a crescent moon. The dorsal fin, on its back, has two parts. It also has a sharply pointed anal fin on its underside. Its long pectoral fins reach past the start of its anal fin.
This fish has small eyes and a straight forehead. Its mouth is quite large and can stick out. When its mouth is closed, its upper jaw is mostly hidden by its cheek bone. Inside its mouth, it has rows of cone-shaped teeth. Some of these teeth are larger, like small fangs.
Colors and Markings
Mutton snappers are very colorful fish. Their backs and upper sides are olive green. This color fades to reddish on their lower sides and belly. They have a black spot between their side line and the spiny part of their dorsal fin.
You might also see two blue stripes under their eyes. The top stripe continues onto their gill cover. Their tail fin has a black edge. When the fish is resting, it shows 10 to 12 dark stripes on its body. These stripes disappear when the fish is swimming. All of their fins are red.
Young Mutton Snappers
Very young mutton snappers, about 1.5 centimeters long, have clear fins. Their bodies have yellowish-brown stripes. As they grow bigger, they get yellow stripes. Their black spot also becomes more noticeable than on adult fish.
Size of the Fish
Mutton snappers can grow up to 94 centimeters long. However, they are usually around 50 centimeters. The heaviest one ever recorded weighed about 15.6 kilograms.
Where Do They Live?
The mutton snapper lives in the western Atlantic Ocean. You can find them from Massachusetts in the north all the way down to Brazil in the south. They are most common in the warmer waters around Florida, the Bahamas, the Caribbean Sea, and the Gulf of Mexico.
These fish prefer clear, fairly shallow waters. They live at depths from 25 to 95 meters. The water temperature they like is between 18.9 and 27.8 degrees Celsius.
Their Homes
Older, larger mutton snappers live near offshore reefs. They also like areas with rocky rubble. Younger fish stay closer to shore. They are often found in places like tidal mangrove creeks, canals, and shallow, protected bays. Young snappers often hide among beds of turtle grass.
Life and Habits
The mutton snapper is a fish that hunts for its food. What it eats changes as it grows up.
What Do They Eat?
When they are very young, mutton snapper larvae eat tiny floating creatures called plankton. They feed near the surface of the sea. Once they settle into the turtle grass beds, they start eating larger plankton and small invertebrates. As they get bigger, their diet includes crustaceans like crabs, snails, and smaller fish. These smaller fish might include grunts and mullets. They hunt and eat throughout the day. Their body color can change depending on how they are feeding. For example, they show their dark striped pattern when they are feeding near the bottom.
Reproduction
Mutton snappers reproduce in all the areas where they live. However, the main place they spawn is in the northeastern Caribbean. They gather in large groups to lay their eggs. In the Caribbean, spawning happens in February. In other places, it happens during the summer.
These fish return to the same spot to spawn each year. They also do it at the same time, based on the moon's cycle. Female snappers release their eggs into the water, where currents carry them. A single female can lay as many as 1.4 million eggs. The males then fertilize these eggs outside the female's body. The eggs hatch about 20 hours later. After hatching, the tiny fish larvae move to shallow waters within 48 hours.
Once spawning is over, the adult fish move to deeper waters offshore. They then tend to stay in one place. Mutton snappers can live for a long time, sometimes up to forty years!
Fishing and Protecting Them
The mutton snapper is an important fish for many types of fishing. People catch them for fun, for business, and for local communities. Their meat is considered very tasty and sells for high prices. The meat from the cheeks and throats of larger snappers is especially prized.
People catch these fish using different methods. These include hooks and lines, nets, longlines, and traps. Some people also catch them by spearfishing. In Florida, they are very popular with people who fish for fun, especially near Cape Canaveral.
Conservation Efforts
Mutton snappers gather in predictable groups to spawn. This makes them easy to catch, which can lead to too many being caught. Young fish are also caught in some areas, making the problem worse.
In the northern parts of their range, studies show that the amount of fish caught by businesses has dropped by over 60%. However, this is because less fishing is happening, not because there are too few fish. In Cuba, the size of the known spawning groups has become smaller. In other places, like parts of Brazil and Colombia, many mutton snappers are being caught.
Scientists estimate that the total number of mutton snappers has dropped by at least 20% over the last 30 to 60 years. Because of this, the IUCN (International Union for Conservation of Nature) lists them as "Near Threatened". This means they could become "vulnerable" if current trends continue. The IUCN suggests that people collect more information about the fish populations. They also recommend protecting the important spawning areas.
