The giant tarantula was shot by dragging the young Oposuum to death, which is considered the first documentation of the spider, who lived on these little marsh cells.
The spider is estimated to be about the size of a plate, and can be seen on the top of a young mouse's opusum, the size of which was the size of softball.
"Oposum was already captured by tarantula and still struggled weakly at this point, but after about 30 seconds, she stopped beating," said biologist Michael Grundler in a statement. "We were very ecstatic and shocked and we could not really believe in what we saw. We knew that we were witnessing something special, but we did not know that this was the first observation until it was "
The team headed by the evolutionary biologist Daniel Rawoski studied the interaction of a predator-victim in the tropical Amazon rainforest To do this, they conducted night surveys, passing through the forest with lanterns and headlights, and browsing the leaves on signs of activity.One evening they heard that the cushions were in the forest bedding.As they covered the earth from where the rustle was coming from, they saw a spider and an opossum.

During a research trip to the Madre de Dios area in the south-eastern Peru Amazon, the team also captured spiders living on frogs, lizards, snakes and fishes, and their results were published in the journal. Preservation of amphibians and reptiles .The images of the trip show various types of spiders and their food.
Spiders are extremely diverse predators, and they are known to eat creatures from all major groups of vertebrates, including birds, mammals, reptiles and fish. They usually have parts of the body that specialize in hunting, such as poison, modified jaws and huge eagles.
Like spider attacks , the team also recorded multiple feasts on vertebrates. In one case, the team saw a large scabbody, a shaggy dog, who ate a dead coral snake. Co-author of the study, Joanna Larson, said: "Coral snakes are very dangerous and can kill people. It was very strange to see who was beaten up by an arthropod. These stinkas are scary animals, in fact.
Rabosky said they found "an underestimated source of death among the vertebrates" in tropical forests. " Amazing number of deaths of small vertebrates in the Amazon, probably due to arthropods, such as large spiders and polygons, "he said.
