Mother and son play fake shrimp to sign baby on bass

The mother and son cleverly disguised as river shrimp in the water to attract fish that are easy to trick, turn it into a host to raise the whole herd.

The species of rainbow oysters live in US rivers and streams often use several rings on the body to simulate the movement of shrimp to lure small mouths into the bait to deposit its offspring, according to National Geographic.

When sea bass catches "shrimp" , the mother immediately spits out a milky white cloud that makes the fish swim away without noticing that it infected tens of thousands of parasitic eggs.

"Boys' ability to imitate is so good , " said David Strayer, a freshwater ecologist at the Cary Ecological Research Institute in New York, USA. "Not only the shape but its movements are very similar to river shrimp".

Mussels spend a lot of effort to spread hairy larvae for many reasons.Larvae live only a few hours or at most two days , according to M. Christopher Barnhart, a mollusk researcher at the University of Missouri. "They are very small, can not feed themselves or swim. Mother boys need to do something to increase their chances of survival such as sneaking into their bodies on a vulnerable host".

After the mother and son sprayed all the larvae into the fish, the tiny larvae clung to the host's gills, fins and skin. The young ones then hide and suck in very small amounts of nutrients from the host in the form of sugar and other liquids.

Most mussels use hosts as a safe haven during their adult preparation. After a few weeks or months, small boys jump down and settle in the river sediment. In most cases, the fish is not harmed."That's why clams are not only downstream. This is their dispersal mechanism, " said Carla Atkinson, an ecologist at the University of Alabama.

Rainbow boys are not masters camouflage under the sole mud. The Higgins eye pearl in the Mississippi River has an outer rim that is very similar to a common native creature that is minnows. This rim even has stripes on the sides and eye spots.

Other species such as the western fanshell in Ozark, USA, released mucus fibers that looked like worms. When the mackerel devours what it thinks is a "worm" , the larvae will shoot.

After the mother and son sprayed all the larvae into the fish, the tiny larvae clung to the host's gills, fins and skin.

In Alabama and Mississippi, the orange nacre species produces a longer version of mucus, which can float and sway between water like fishing lines. Each strand is baited like a small fish or insect larva at the end, contained inside countless larvae waiting. When the fish bite, the mussel larvae break and cling to the host.

In Europe, a boy named spurting mussel uses a tongue-like leg to climb up the river bank so that they can spray water filled with larvae on the water surface."Its way is very similar to sprinkling fish food in aquariums. Tuberculosis comes to see what is there and infects parasitic larvae , " explains G. Thomas Watters, a boy species expert at Ohio University.

Of all the male methods used to take advantage of fish, Barnhart admires the most Epioblasma, native animals in the United States. This mussel usually opens its shell, using meat in its body as bait to attract fish. When the fish rushed forward, the shell of the shell collapsed like a trap. The son sprayed on its prison mouth millions of larvae before releasing the fish."They are guys who really bite , " Barnhart commented.
