Selenotholus Kotzman Australian Tarantula

The Selenotholus Kotzman is a remarkable Australian tarantula known for its impressive size, robust build and understated appearance. Rather than relying on bright colouration, this species stands out through its substantial body, powerful legs and classic earthy brown tones.

As a member of the Selenotholus genus, the Selenotholus Kotzman is an intriguing species for tarantula enthusiasts interested in Australia’s diverse native spider fauna. Females can reach a leg span of approximately 5 inches (12.7 cm), making mature specimens particularly impressive additions to a specialist tarantula collection.

Scientific Classification

• Scientific Name: Selenotholus sp. “Kotzman”
• Genus: Selenotholus
• Type: Australian terrestrial tarantula
• Common Name: Selenotholus Kotzman
• Distribution: Australia
• Habitat: Forests, grasslands and other terrestrial environments
• Adult Female Size: Up to approximately 12.7 cm leg span

Appearance

The Selenotholus Kotzman has an understated but impressive appearance, featuring a predominantly velvety brown body with subtle variations in colour across the carapace, abdomen and legs.

While it may not display the vivid colours or contrasting patterns found in some other tarantula species, its appeal comes from its substantial build and classic earthy appearance.

The species has strong, robust legs and prominent fangs that are used to capture and subdue prey. Mature females can reach a leg span of approximately 12.7 cm, giving them a substantial presence despite their relatively understated colouration.

Colouration can vary between individual specimens and may change in intensity as the tarantula matures and undergoes successive moults.

Natural Habitat & Distribution

The Selenotholus Kotzman is native to Australia and is associated with terrestrial habitats including forests and grassland environments.

Australian tarantulas can inhabit a variety of environments, with natural shelter provided by soil, leaf litter, vegetation, fallen timber and other ground-level debris.

In captivity, providing suitable substrate, shelter and environmental conditions can help replicate some of the features of its natural habitat.

Behaviour

Selenotholus Kotzman is primarily nocturnal, meaning it is generally most active during the evening and nighttime hours. During the day, it may remain concealed within its shelter or burrow.

Like other tarantulas, it is an opportunistic predator that feeds on insects and other appropriately sized small invertebrates.

Its powerful legs and fangs allow it to capture prey efficiently. Individual temperament can vary between specimens, so the species should be treated with respect and maintained primarily as a display animal rather than being handled unnecessarily.

Care Requirements

Selenotholus Kotzman should be housed in a secure terrestrial enclosure that provides suitable substrate, ventilation, shelter and access to fresh drinking water.

A suitable enclosure should include:

• Appropriate terrestrial substrate
• Sufficient substrate depth for burrowing
• Cork bark or another secure hide
• A shallow water dish
• Good ventilation
• Suitable moisture levels
• Adequate floor space
• A secure, escape-resistant lid

The enclosure should provide stable conditions without allowing the substrate to remain constantly saturated. A suitable moisture gradient can allow the tarantula to select its preferred conditions.

As the tarantula develops, its enclosure should be appropriately upgraded to provide sufficient space for its increasing size.

Feeding

Selenotholus Kotzman is an opportunistic predator and can be fed a range of appropriately sized feeder insects.

Suitable prey can include:

• Crickets
• Roaches
• Woodies
• Other appropriately sized feeder insects

Feeding frequency depends on factors such as age, size, metabolism, temperature and individual appetite. Younger specimens generally require more frequent feeding, while mature tarantulas can usually be fed less often.

Uneaten prey should be removed where appropriate, particularly if the tarantula begins showing signs of an upcoming moult.

Fresh drinking water should always be available.

Moulting

Like all tarantulas, Selenotholus Kotzman periodically moults its exoskeleton as it grows. A specimen approaching a moult may become less active, refuse food or spend increased amounts of time inside its shelter.

During this period, the tarantula should be left completely undisturbed. Live feeder insects should not be left inside the enclosure while the spider is moulting, as they may potentially injure a vulnerable specimen.

Maintaining suitable environmental conditions and providing access to clean water are important aspects of successful tarantula husbandry.

Growth & Adult Size

Female Selenotholus Kotzman can reach approximately 5 inches, or 12.7 cm, in leg span. This gives mature females an impressive presence and makes them particularly appealing to collectors who prefer larger terrestrial tarantulas.

Growth rates can vary depending on genetics, feeding, temperature, sex and overall husbandry. As with many tarantula species, males and females can differ considerably in mature size and lifespan.

Why Keep Selenotholus Kotzman?

Selenotholus Kotzman is an excellent choice for keepers interested in large Australian tarantulas with a more understated and natural appearance.

Its velvety brown colouration, robust body, powerful legs and impressive adult size give the species plenty of visual appeal without relying on bright or highly contrasting markings.

For collectors interested in Australian tarantulas, Selenotholus offers an opportunity to keep a less commonly encountered genus and observe the natural nocturnal and predatory behaviour of a substantial terrestrial spider.
