Fortunately, No Spider in India is considered harmful to humans and no fatal bites have ever been recorded. Spider bites are rare unlike snakes, big spiders do not prefer to dwell in human population. So, the answer is Yes, there are venomous spiders in India. Infact all of them are venomous.
Lizards generally have small heads, long bodies and long tails. With so many species of lizard, it’s understandable that they come in a wide variety of sizes. The largest lizard is the Komodo dragon. It grows up to 10 feet (3 meters) long and weighs up to 176 lbs. (80 kilograms). The smallest lizard is the tiny dwarf gecko, which grows to 0.6 inches (1.6 centimeters) long and weighs .0042 ounces (120 milligrams).
Most lizards are active during the day. Lizards are cold-blooded animals, which means they rely on their environment to help warm their bodies.
Lizards are carnivores, which means they eat meat. A typical diet for a lizard includes ants, spiders, termites, cicadas, small mammals and even other lizards. Caiman lizards eat animals with shells, such as snails.
- There are approximately 38,000 known species of spiders. Scientists believe there are probably as many more to be discovered
- Spiders are found on every continent except Antarctica
- Spiders are vital to a healthy ecosystem. They eat harmful insects, pollinate plants, and recycle dead animal and plants back into the earth. They are also a valuable food source for many small mammals, birds, and fish.
- Spiders eat more insects than birds and bats combined
- Web-weaving spiders have two or three claws at the tip of each leg that they use to swing from strand to strand without getting stuck in the sticky part of their web. Additionally, a spider’s body has a special oily substance that keeps it from getting stuck in its web.
- When a spider travels, it always has four legs touching the ground and four legs off the ground at any given moment.
- Spiders have blue blood. In humans, oxygen is bound to hemoglobin, a molecule that contains iron and gives blood its red color. In spiders, oxygen is bound to hemocyanin, a molecule that contains copper rather than iron.
- A spider’s muscles pull its legs inward, but cannot extend its legs out again. Instead, it must pump a watery liquid into its legs to push them out. A dead spider’s legs are curled up because there is no fluid to extend the legs again.
- The world’s biggest spider is the goliath spider (Theraphosa blondi). It can grow up to 11 inches wide, and its fangs are up to one inch long. It hunts frogs, lizards, mice, and even small snakes and young birds
- The world’s smallest spider is the Patu marplesi. It is so small that 10 of them could fit on the end of a pencil.
- The most deadly spiders in the world include the black widow, funnel web, and brown recluse spiders. One of the most feared spiders in the world, the tarantula, actually has surprisingly weak venom and a bite that feels more like a wasp sting.
- The most venomous spider in the world is the Brazilian Wandering Spider, or the banana spider. This aggressive spider wanders the forest floors of Central and South America looking for food. Just a small amount of venom is enough to kill a human.
- The silk in a spider’s web is five times stronger than a strand of steel that is the same thickness. A web made of strands of spider silk as thick as a pencil could stop a Boeing 747 jumbo jet in flight. Scientists still cannot replicate the strength and elasticity of a spider’s silk.
- In tropical regions, net-throwing spiders make a small silken web that they throw over their prey.
- The funnel web spider is an aggressive spider that attacks and bites people. Its poison has been known to kill in just 15 minutes. Fortunately there is an antivenom, and deaths from this spider are now rare.
- Wolf spiders can run at speeds of up to 2 feet per second
- Most spiders found in homes have adapted to life indoors. They have little chance of surviving outdoors.
- Spiders are blamed for all kinds of bumps, rashes, and growths. However, unlike mosquitoes or ticks, spiders don’t feed on human blood and they have no reason to bite a human unless they feel threatened or surprised. Additionally, spiders do not typically bite sleeping humans.
- A strand of spider silk long enough to encircle Earth would weigh just over a pound.
- There is a spider in Hawaii that looks like it’s smiling. Dubbed the “Hawaiian happy-face spider,” the cheerful-looking spider is under the threat of extinction.
