Omothymus Spider/ Malaysian Earthtiger Tarantula Length

Omothymus Spider Size

Peninsular Malaysia is home to the Malaysian Earth Tiger tarantula, scientifically known as Omothymus Schioedtei, a species of spider in the Theraphosidae family. The Omothymus is unquestionably a large species of spider because it is a member of the tarantula family.

Here’s a breakdown of their size:

Omothymus schioedtei (Malaysian Earth Tiger):

  • Leg span: Up to 22 cm (8.7 inches)
  • Carapace length: Over 3 cm (1.2 inches)
  • Body length: Females are larger than males, reaching around 9-10 cm (3.5-4 inches) in leg span. Males are slightly smaller, around 7-8 cm (2.8-3.1 inches) in leg span.

Leg span 22 cm 8.66 in 

Other Omothymus species:

  • Generally smaller: Now, the rest of the Omothymus species is a bit more mysterious in terms of size. While they generally tend to be smaller than their Malaysian Earth Tiger relative, specifics are a bit elusive.
  • Possible exceptions: Some reports hint that Omothymus fuchsi might match up in size, but we’re awaiting official confirmation.

Isn’t nature’s diversity simply captivating?”

Omothymus Spider Weight

Among the toughest tarantulas are those of the genus Omothymus. They are quite self-sufficient and won’t need much assistance to survive. 

Taking a stab at the numbers:

Okay, so we might not have the official weights since there’s various factors affecting it, but you’ll get a rough idea from below:

Estimates Based on Size:

  • Larger individuals: Imagine this – if we stack up our leading lady Omothymus schioedtei against heavyweight champs like the Goliath Birdeater (they tip the scales at a whopping 150-200 grams (5.2-7 oz), some estimates suggest an Omothymus schioedtei female could weigh around 100-150 grams (3.5-5.2 oz).
  • Males and smaller species: Now, for the males and the other Omothymus species, we’re talking much lighter numbers. Picture them gracefully dancing on the scales at maybe 50-75 grams (1.7-2.6 oz) or perhaps even less. It’s like the difference between carrying a backpack full of textbooks and just a light novel.

Important points to remember:

Estimated Adventures:

  • Let’s set the record straight – these estimates are like the Sherlock Holmes of the spider world. We’re doing our best with the data we’ve got, but the actual weights are a bit of a mystery. Think of it as predicting the weather in a rainforest – it’s a calculated guess, but nature likes to keep us on our toes. So, these ranges are more like friendly nudges than concrete facts.

Weighing Woes:

  • Now, here’s the tricky part – imagine trying to get an accurate weight reading from a tarantula. It’s like asking a cat to sit still for a family portrait – not exactly a walk in the park. These creatures are delicate and quite the drama queens when it comes to being weighed. So, while we’re eager for the deets on their weightlifting prowess, getting reliable data is like chasing a rainbow. Stressing them out in the wild just to put them on the scales? Not our style. Therefore, reliable weight data might be scarce

In the spider weight-measuring Olympics, it’s a game of patience and understanding. So, keep those estimates in your back pocket and embrace the mystery!

Here’s A Fun Reddit About Omothymus Spider Size

Omothymus Spider Size Comparison To Human Hand

Omothymus Spider Size compared with human hand

Knowing an object’s dimensions alone is frequently insufficient to visualize and comprehend how big or small it is. 

Similar to determining whether a spider is large or small, you must have a comparison point when dealing with spiders. We can use the spider as a benchmark by comparing it to other species or different kinds of spiders. So, to begin with, let’s see what the Omothymus Spider would look like on a human hand. 

On average, an adult human hand is about 7.6 inches long in size. While the Omyothymus spider is about 9 inches long with an additional leg span of 8.66 inches.

This shows how large the species of spider is. It is so large that it would not even fit on one hand. And, considering its weight too, the spider is very heavy to hold stable on our palms. 

Omothymus Spider Vs Wolf Spider Size Comparison

Omothymus Spider Size compared with other spiders

Now that we have compared the Omothymus Spider with other species such as humans, let’s compare it with other types of spiders. 

This would help you visualize the size difference between two different types of spiders. Firstly, we will talk about the wolf spider with respect to the Omothymus Spider. 

To begin with, Wolf spiders run much faster than other types of spiders. The vast majority of the thousands of species that make up this family hunt and pounce on their prey instead of weaving webs. 

They are fierce hunters that can move quickly and are able to live in leaf litter or burrows underground. The family of wolf spiders is a large one in terms of size and mass.

The Wolf spiders are much smaller than the Omothymus spiders in size; they can grow to a length of two to three inches. The overall body length of the wolf spider is between 10 and 35 mm, and it weighs less than an ounce (0.4 to 1.38 in). 

In contrast, the Omyothymus spider is about 9 inches long with an additional leg span of 8.66 inches. The Omothymus is large and massive, it would crush the Wolf spider if by mistake it gets on top of it. 

Spider type Overall Body lengthLeg span Weight 
Omothymus Spider 8-9 inch8.66 inches 41.6 ounce 
Wolf spider 0.4-1.38 inch 2-3 inch less than an ounce

Omothymus Spider Vs Brown Recluse Size Comparison

A specialized and incredibly rare spider species is the brown recluse. There is almost no chance of being bitten by them, and they cannot be found outdoors. Brown recluse bites are thought to frequently result in large, necrotic lesions.

Adult brown recluse spiders are roughly the size of a quarter, though they can vary in size. Rarely do tiny recluse spiders grow to be half an inch long? 

A brown recluse spider has an overall length of 6 to 20 millimeters (0.24 to 0.79 in) and a leg span of approximately 2.5 cm (1 inch). 

In addition, Brown recluse spiders are tiny and only weigh a little over 0.001 lbs (0.45 grams). On the other hand, the Malaysian tarantula is a huge and bulky spider.
