Consequences of Putting Your Finger in a Big Venus Fly Trap

You might have seen in the movies that giant insectivorous plants are attacking animals and humans. This is a fiction where the small insectivorous plants such as Venus Fly Trap have been magnified for a fearful presentation. What will happen if you get your fingers trapped in a life-size Venus Fly Trap?

These plants are known for trapping animals and insects and slowly digesting them to get the required amount of nitrogen. These plants are delicate in nature and do not have the strength to cause harm to our fingers. Despite this fact, we do fear seeing an animal trapping our fingers. Isn’t it?

What Is a Venus Fly Trap?

Commonly known as Venus Fly Trap, this plant is capable of trapping smaller animals such as insects, rodents, and reptiles inside their clawed leaves. The scientific name of this plant is Dionaea muscipula. This plant has evolved to create unique leaves with claws on the top edge. The leaves are divided into two equal halves representing jaw-like shapes with claws at the edges.

When an insect triggers the internal hair on the muscular part of the leaves, the leaves close with the insect inside. Slowly, digestive enzymes are released to decay the nitrogenous mass to absorb the required nutrients.

This type of evolution where a carnivorous plant depends on animals as a nitrogen source is due to the fact that the soil they grow on does not offer proper nutrients. Moreover, they have also lost the ability to fixate nitrogen through their roots or any other organ system. If you see the Venus Fly Trap images, you will learn that these plants do not have the proper environment to grow like normal plants.

Features of a Venus Fly Trap

A Venus Fly Trap, also called the fly catcher plant, has exceptional botanical features. They are as listed below.

  1. It is a flowering plant and has carnivorous eating habits. It catches insects, rodents, and small reptiles to get their nitrogenous requirement fulfilled.

  2. The movement of their leaf lobes is called thigmonasty. It is a response that is non-directional and is activated or displayed when touched. The Venus flytrap plant will only show such movement when the bristles or hair inside the lobes are touched to conserve energy. These bristles or hair are called trichomes. They will trigger closing the leaf lobes when touched multiple times, not once.

  3. The bristles on the edges of leaf lobes look like claws. They are not used for biting or imparting harm. They are used as interlocking devices so that the trapped insect or animal cannot leave easily.

  4. This plant grows in acidic and moist soil that does not deliver the right nutrients. Hence, trapping animals for nutrition is an evolutionary trait.

  5. It also performs photosynthesis to some extent but the major nutrition comes from trapping small insects and animals.

  6. The Venus flytrap flower can be seen blooming at the top of the plant way above the trapping leaves.

  7. A leaf can only consume 3-4 times before it closes forever.

  8. The reaction time of its leaves is 1.5 milliseconds. 

What Happens When We Put a Finger in a Big Venus Fly Trap?

This might sound no less than a nightmare but putting your finger in one of the leaves of Venus Fly Trap will not cause any harm. The leafy parts grow closer to the ground where the crawling insects and animals are found more.

The closing leaves might be lethal to the small insects with less power to tackle such pressure but they cannot harm a human finger. You can refer to these closing leaves as the mouths and stomachs of the plant. A trapped insect will be slowly digested and the required nitrogenous nutrients will be absorbed. In the Venus Fly Trap finger case, you can easily pull out as the lobes are very delicate.

If you put your finger a little too long, the strong enzymes can start digesting your skin externally. Hence, there is no need to experiment and find out how much time plants like Venus Fly Trap takes to digest your finger!

Venus Fly Traps Can Count!

Jennifer Böhm, Sönke Scherzer, and Dr Hedrich, the leading biophysicists of Tasmania, researched and suggested that these plants can actually count with their trichomes.

The trichomes are the small projections inside the lobes of the trapping leaves. When touched by a moving insect, they do not send signals to close the lobes but start counting. Researchers think that it is a great way to reserve energy. When the plant is sanguine that the insect is inside the trap properly, they tend to close the lobes with a snap. Well, this is some information about the Venus Fly Trap we did not know!

In a Nutshell

We can conclude that trapping your fingers inside a Venus Fly Trap will not cause any harm. They do not have the jaw pressure of a hyena. These leafy lobes know how much pressure is to be applied to trap a small insect. Hence, you do not have to be afraid of the Venus finger conundrum anymore.  

The Venus Fly Trap eating insects is indeed a great scene to adore. It is the miracle of nature where a plant hunts for its living. There are other examples such as the pitcher plant, sundew plant, drosera capensis, etc. that can hunt prey by using the same method but different techniques.

A common feature of all these plants is that all of them produce something that attracts insects and smaller animals. These plants cannot harm us as we can free our fingers anytime we want.
