Puppy-Sized Spider Surprises Scientist in Rainforest

Piotr Naskrecki- an Entomologist and photographer at Harvard University’s Museum of Comparative Zoology caught a new Puppy-Sized Spider. This spider is also known as the South American Goliath bird-eater, having scientific name, “Theraphosa blondi”. The specimen was taken to the lab afterwards. It was also found that it’s a female. After further study, it has been deposited in a museum finally.

A Goliath bird-eater tarantula spider surprised scientist Piotr Naskrecki when he looked for insects in the Guyana rainforest.

According the Guinness World Record, “the colossal arachnid is the world’s largest spider”. Naskrecki reporting to Live Science stated that

“I was taking a night-time walk in a rainforest in Guyana, when I heard rustling as if something were creeping underfoot. When I turned on the light, I expected to see a small mammal, such as a possum or a rat but couldn’t quite understand what I was seeing. Later I realized that it is a puppy sized spider.”

Moreover, he reported that the its leg span can reach up to a foot, may be around 30 centimetres, or about the size of “a child’s forearm,” with a body the size of a large fist. On his blog, he wrote that the spider can weigh more than 6 oz. i.e. 170 grams. It is almost equal to the weight of a young puppy.

The Goliath bird-eater can weigh up to 6 oz and have a leg span of almost a foot.

Sources also reported that the size of its leg is bigger than the bird eater but it’s more delicate than bird-eater. Naskrecki suggests that comparing the two would be “like comparing a giraffe to an elephant. Its feet have hardened tips and claws that produce a very distinct, clicking sound, not unlike that of a horse’s hooves hitting the ground”.

Moreover he also observed that the spider used to rub its hind legs against the abdomen. Soon he realized that spider was sending out a cloud of hairs with microscopic barbs on them. And when these hairs get in the eyes or other mucous membranes, they are “extremely painful and itchy and can stay there for days.

The spider's venom is not poisonous to humans.
It has also been reported that the spider is not dangerous to human at all. Even if its bite, it can do no harm to human. The spider basically relies on frogs, insects and earth worms. If it find a nest, it punctures and drink bird’s eggs as well.

Moreover Naskrecki also said,

“Bird-eaters are not very common spiders. I’ve been working in the tropics in South America for many, many years, and in the last 10 to 15 years, I only ran across the spider three times”.
