Squilla mantis

The spot-tail mantis shrimp lives in the sea.

It has long arms like spears. It uses these to catch soft food. This shrimp is brown. It has two white spots on its tail. It digs holes in the sand and mud. It stays in its hole during the day. At night, it comes out to hunt. It likes to eat crabs and squid. This shrimp is also caught by fishers for food.

The spot-tail mantis shrimp lives in the sea.

It lives in the Mediterranean Sea and the Atlantic Ocean. This shrimp is a spearer. It has long, spiked arms. These arms act like spears to catch soft prey. Most of these shrimp are dull brown. They have two brown eye spots on their tail. These spots have white circles around them.

These shrimp dig burrows in mud or sand. They stay in their holes during the day. They come out at night to hunt. They also come out in winter to mate. They eat many things like crabs and squid. They even eat algae.

In the spring, females lay eggs. They use a sticky liquid to hold eggs to their legs. The mothers stay in their holes to care for them. They do not eat during this time. The eggs hatch into tiny larvae. These young shrimp float in the water. They grow through ten molts. A molt is when a shrimp sheds its old shell. Soon, they settle on the sea floor.

The spot-tail mantis shrimp is a special sea creature.

People also call it the pacchero or canocchia. It lives in shallow coastal waters. You can find it in the Mediterranean Sea. It also lives in the Eastern Atlantic Ocean. This shrimp is a spearer type. This means it has special front limbs. These limbs look like long, spiked spears. They help the shrimp catch soft prey. Most of these shrimp are a dull brown color. They have two brown eye spots on their tail. These spots have white circles around them.

This shrimp has a busy way of life. It digs burrows in sandy or muddy bottoms. It stays inside its hole during the day. It comes out at night to hunt for food. It also comes out in the winter to mate. The shrimp eats many different things. It eats crabs and squid. It also eats worms and small fish. Sometimes it even eats algae. It is an opportunistic predator. This means it eats whatever food it can find nearby. Some shrimp even follow fishing boats to eat dead animals.

Making new shrimp is a long process. The mating season happens in winter and spring. In the Adriatic Sea, this peaks between February and March. In the Ligurian Sea, it peaks in April.

After laying eggs, the female must care for them. She uses a sticky liquid from her body. This liquid helps her attach eggs to her legs. The mother stays in her burrow all spring. She does not leave or even eat during this time. The eggs hatch between late spring and late summer. The tiny babies are called alima. They float in the water during the summer.

These little alima go through ten molts. A molt is when a shrimp sheds its old shell. After that, they settle on the sea floor. They grow into adults by the end of the year. Most female shrimp spawn within their second year. Some might live to a third year of life. The shrimp lives in many places. It lives near the Nile and Po rivers. It is also found near the Ebro and Rhône rivers. It lives from the Gulf of Cádiz down to Angola. You can also find them near the Canary Islands and Madeira.

Humans catch these shrimp for food. It is the only mantis shrimp fished commercially in the Mediterranean. Over 7,000 tons are caught every year.

Most of this is caught near Italy. Spain is also a big place for catching them. Smaller fisheries exist in France, Israel, and Egypt. In the Gulf of Cadiz, people call them galera. They are often caught in nets meant for other fish. This is called by-catch. Fishing is highest in the winter. This is when the adults come out to mate.

The spot-tail mantis shrimp, known scientifically as Squilla mantis, is a fascinating crustacean.

It lives in the shallow coastal areas of the Mediterranean Sea and the Eastern Atlantic Ocean. In some regions, people call it "pacchero" or "canocchia." This species is highly significant to humans because it is a commercial resource. It is actually the only species of mantis shrimp in the Mediterranean that is fished on a large scale. Because it is so abundant, it has become a valued part of local seafood economies.

Physically, Squilla mantis belongs to a specific group called the "spearer" type. This classification is based on how the shrimp uses its front limbs, or raptorial claws. Instead of smashing shells, these limbs are shaped into long, spiked spears. The shrimp uses these specialized tools to strike and capture soft-bodied prey. Most of these shrimp have a dull brown color to help them blend in. A key identifying feature is found on its telson, which is the tail segment. There are two brown eye spots at the base of the telson, and they are circled in white.

These shrimp prefer specific environments to build their homes. They dig burrows into sandy or muddy bottoms near the coastline. They thrive in areas where there is a lot of run-off from large rivers. For example, the outflows from the Nile, Po, Ebro, and Rhône rivers provide ideal conditions. They are most commonly found at depths between 1 and 10 meters. However, they can sometimes be found in deeper waters up to 30 meters. Their lifestyle is very predictable and follows a strict daily routine.

Squilla mantis is a nocturnal and sedentary animal. This means they stay in one general area and are most active at night. During the daylight hours, they remain hidden safely inside their burrows. They emerge under the cover of darkness to hunt for food. They also come out of their burrows during the winter months to mate. Interestingly, some other species of shrimp, like Athanas amazone, live inside the burrows of S. mantis. Scientists are still studying this relationship to understand why they live together.

As opportunistic predators, these shrimp eat almost anything available in their environment. Their diet includes various crustaceans like crabs and decapods. They also hunt mollusks, such as squid and bivalves, as well as worms and small fish. They have even been seen eating algae or the egg masses of common cuttlefish. Sometimes, they even follow fishing boats to scavenge on dead animals.

Because they are opportunistic, they will even practice cannibalism by eating others of their own species.

The life cycle of the spot-tail mantis shrimp is a complex process. The reproductive season occurs during the winter and spring. In the Adriatic Sea, maturity peaks between February and March, while in the Ligurian Sea, it peaks in April. After laying eggs, the female uses a sticky secretion from her cement glands to attach them to her front legs. She then stays in her burrow to incubate them through spring and early summer. During this time, she does not leave her home or even eat. The eggs eventually hatch into larvae called alima, which float in the water column. These larvae go through ten aquatic molts before settling on the sea floor to grow into adults.

Human fishing of Squilla mantis is a major industry in certain parts of the world. Every year, over 7,000 tons of these shrimp are caught. A massive 85% of this total catch comes from the Italian shores of the Adriatic Sea. Spain is another important center for catching them, especially in the Gulf of Cadiz where they are called "galera." In other places, smaller fisheries operate in France, Israel, and Egypt. Much of the shrimp is caught as by-catch, which means they are caught in nets intended for other animals like sole. Because they are mostly caught this way, the fishery is not specifically regulated.
