The Amazing Evolution of the Pet Omothymus Spider

The Omothymus spider is typically non-threatening to individuals, although it possesses the capability to administer stings that may cause discomfort.

While tarantulas are commonly kept as pets in domestic settings, it is advisable to house them in enclosures due to their nocturnal hunting behaviour.

Tarantulas can be classified into two distinct categories based on their behaviour: active tarantulas and docile tarantulas.

The species Omothymus schioedtei exhibits a notable degree of assertiveness and displays minimal fear towards human presence.

The organisms in question exhibit high levels of activity and have been observed to consume diminutive organisms such as flies and moths.

Due to their pronounced aggression and territorial behaviour, it is advisable to house Tarantulas in a spacious enclosure alongside conspecifics exhibiting comparatively lower levels of aggression.

Omothymus schioedtei is a notable arboreal tarantula species belonging to the subfamily Ornithoctoninae, characterized by its substantial size and vibrant colouration.

The arachnid in question exhibits a considerable size, characterized by a leg span measuring 22 cm and a carapace length exceeding 3 cm.

A clear sexual dimorphism is observed. The male displays an olive green colouration, accompanied by subtle yellow striations on its legs.

The male exhibits a tibial apophysis that is characterized by its blunt morphology, along with the presence of long and slender legs.

The determination of the sex of subadult males can be accomplished through the utilization of the epigynal fusillae method.

Additionally, it is noteworthy that these individuals undergo a progressive increase in green colouration with each successive moult until reaching maturity.

The distinction between subadult males and subadult females is particularly evident through their ventral colouration, with the former exhibiting a green hue and the latter displaying a black hue.

How Do I Describe the Taxonomy of the Omothymus Spider?

The species Omothymus schioedtei was initially documented by Tamerlan Thorell in 1891, serving as the representative species for his newly established genus, Omothymus.

In the year 1903, Eugène Simon established a synonymy relationship between the taxonomic genera Omothymus and Cyriopagopus, resulting in the reclassification of Omothymus schioedtei as Cyriopagopus schioedtei.

As of March 2017, the taxonomic classification of several genera of spiders in East Asia remained ambiguous.

In 2015, Smith and Jacobi conducted a restoration of the species, reverting it back to its original designation as Omothymus schioedtei.

This decision was based on the argument that the type species of the genus Cyriopagopus, namely C. paganus, lacked distinctiveness from the genus Haplopelma, in contrast to C. schioedtei.

Furthermore, the taxonomic classification of Haplopelma has been synonymized with Cyriopagopus.

 

How Do I Identify the Omothymus Spider?

The Malaysian Earth Tiger Tarantula exhibits a visually captivating and noteworthy physical appearance.

This species, belonging to the tarantula family, exhibits the characteristic anatomical features of eight legs and two body parts, including a notably enlarged and spherical abdomen.

It is highly advisable to promptly seek medical consultation from a healthcare professional in the event that one experiences symptoms suggestive of a bite inflicted by an earth tiger tarantula.

 

How Do I Describe the Habitat of the Omothymus Spider In the Wild?

The Malaysian Earth Tiger tarantulas are typically observed inhabiting the coastal forests located in Sabah, Malaysia, primarily within an elevation range spanning from sea level up to 300 meters.

The native habitat of this species is typically located within the primary lowland and foothill monsoon forests, where they inhabit hollow trees situated at considerable heights.

The depletion of the Malaysian rainforest created new ecological opportunities for the tiger spider.

This adaptation facilitated the hunting process for tigers, thereby enhancing their ability to acquire a wider range of prey. The trees underwent a process of falling, while the plants experienced growth.

However, the tiger spiders remained stationary, inhabiting the forest floor. This particular step has had a beneficial impact on the habitat of the tiger spider.

 

How Do I Describe the Habitat of the Omothymus Spider As Pets?

For the purpose of accommodating an Omothymus schioedtei tarantula, it is advisable to employ a spacious enclosure made of either plastic or wood, measuring no less than 2 feet in length and 1 foot in width.

The enclosure should be equipped with substrates of a minimum depth of 10 inches, such as plasterboard, wood chips, or gravel.

It has been determined that a spacious aquarium is an optimal enclosure for accommodating earth tigers due to its ability to offer the essential elements of humidity, heat, and airflow.

Ensuring proper care for an earth tiger tarantula is of utmost importance. For instance, it is advisable to avoid excessive humidity levels within the container.

An optimal humidity range is typically considered to be between 30% and 50%. This segment enables the tarantula to regulate its internal temperature.

Simultaneously, it is imperative to ensure that the humidity levels do not fall below an acceptable threshold. It is imperative to maintain the humidity levels within the range of 30% to 50%.

Sufficient environmental moisture is necessary for the earth tiger tarantula to facilitate silk production and undergo the process of moulting. It is imperative to ensure that the container is equipped with ventilation apertures.

 

How Do I Describe the Temperature Requirement of the Omothymus Spider?

The spider’s behaviour and activities are governed by temperature and humidity. The tarantulas thrive during the winter season when exposed to temperatures in the range of the low 50s Fahrenheit.

It is recommended that humidity levels be maintained within the range of 50-70% Fahrenheit. The tarantula exhibits a preference for inhabiting relatively confined spaces.

However, the dimensions of the box are of significance. The provision of adequate space for movement is essential for their well-being.

In instances where the enclosure is insufficiently spacious, their survival may be compromised as a result of restricted mobility and limited access to nourishment.
