Tom's Big Spiders - Tarantulas and Inverts

Kids EN ↓ 390 episodes

A podcast devoted to the proper care and upkeep of tarantulas and other inverts. After keeping a G. porteri for over 16 years, I decided that I wanted to add another tarantula to my collection. Several years later, I now keep over 100 specimens and 90+ different species. It’s safe to say that I am now completely addicted to the hobby. I’m NOT an expert, and I’m currently still learning about keeping these fascinating creatures. In fact, there are so many species, that I suspect that I’ll still be learning years from now. A teacher by trade, I enjoy passing along what I’ve information and techn...

The Future of the Podcast and Signs Your Old Tarantula Is Dying 28.04.2024

If someone would have told me back in early 2018 that this podcast experiment would continue for over 300 episodes, I would have laughed. But here we are, in our seventh year, still churning out shows. That said, I always worry that the program will eventually jump the shark and overstay its welcome. To kick this one off, we’ll discuss the fine line I try to walk producing shows that will appeal t...

The Best Tarantula Species for Folks Raising up Their First Slings 21.04.2024

As I've spent more time keeping tarantulas, I've realized that questions "what is a good beginner species?" and "what is a good species to raise as a first time sling? have two very different answers.  Just because a species is easier to care for as an adult does not always make it an easy one to raise up. In this episode, I'll discuss the species I tend to recommend...

The Importance of Establishing Routines with Growing Tarantula Collections 15.04.2024

How do you know when you’re getting too many tarantulas? How can you tell when you’re reaching what should be your limit? In this episode, we’ll discuss the importance of establishing routines and setting boundaries early on to avoid having your collection turn into a hoard. 

Tarantula Max Lifespans - A Realistic Discussion 07.04.2024

I've encountered this scenario many times...an upset keeper emails me to ask what he did wrong because his adult female didn't make it to the supposed max life expectancy.  In many cases, it sounds like the animal died of natural causes, but the thought that it should have lived longer can eat away at a concerned keeper.  In this episode, we discuss some of the maximum lifespans given fo...

The Goliath Birdeaters - Theraphosa Genus Review 24.03.2024

Dos and Don'ts When Ordering Tarantulas Online 17.03.2024

To start this one off, I share some of the feedback I got from last week's episode and respond to a couple comments. Then, at 21:25,  it's been five years to the day when I last covered some tips for ordering tarantulas online. In this episode, we will review the dos and don't as well as discuss some new issues that have presented themselves over the last five years. 

The "Domestication" of Tarantulas - Why our Pets Are Not Quite Wild Animals 10.03.2024

A couple of years ago, I stumbled on an article about the "inadvertent domestication" of animals raised for the sole purpose of being released back into the wild. This is when, despite our best efforts, captive animals were becoming inadvertently domesticated by temporarily or even permanently adapting to a captive environment , which was making them less fit to survive in the wild. This...

Why Bother Asking? When Keepers Ask Questions and Ignore the Answers 03.03.2024

I've been doing this a while now, and there is one occurrence that I will never understand...when keepers ask for advice and then ignore it.  Luckily, it doesn't happen often, but when it does, the results can be quite tragic. In this episode, we'll discuss a few of the more egregious experiences I've had with this type of behavior.

Tarantula Substrate - Some Inexpensive Mixes 25.02.2024

Over the years, I've continued to constantly switch up what I use for substrate when it comes to housing my tarantulas. In this episode, I review what I've used in the past and share an inexpensive "recipe" I'm currently using that yields a LOT of substrate for very little money. 

Tarantula Collection Killers 19.02.2024

In this episode, we discuss some instances where folks have lost large parts or all of their collection due to mishap or an overlooked environmental hazard. 

I Want a Tarantula - Where Do I Start? 11.02.2024

Within the past couple weeks, I spoke with two teenagers who were interested in getting their first tarantula. Both had many questions about where they should start and what they should prepare for. In this episode, I lay out several things anyone thinking about getting a tarantula should do...and some things that they shouldn't . 

How I've Tweaked My Fossorial Tarantula Setups 04.02.2024

First, we discuss the "controversy" a recent episode caused. Then, I field a question from a long-time YouTube subscriber about changes that I've made in how I set up fossorial tarantula enclosures. 

Pamphobeteus vs. Phormictopus! The Battle of Two Giant Tarantula Genera 28.01.2024

Well, it had to be done! In this episode, two popular genera of giant tarantulas will duke it out for hobby superiority! Okay, that's a bit dramatic; in reality, we will compare the two genera and talk about the similarities and differences.

The One Issue in the Tarantula Hobby I Will Never Overcome 14.01.2024

To start this one off, we'll discuss some feedback to last week's episode. Then, after reflecting on 10 years of doing the TBS stuff, I realized that there is one major issue that I will never overcome. 

Tarantula Feeding Schedules and Fat Ts 07.01.2024

Recently, I've received some comments on my YouTube videos with folks saying that my tarantulas are "skinny" or "underfed", which left me a bit confused. However, after speaking with a hobby friend, I realized that, through social media, many folks new to the hobby may be exposed to photos of chubby Ts. For many, a spider with a bloated abdomen is the norm. In this episode...

Do Tarantulas Have "Personalities"? 31.12.2023

Happy New Year! In this episode, I give my take on whether or not it's appropriate to say that tarantulas have "personalities." We will also discuss whether tarantulas need enrichment to avoid boredom.

The A. geniculata vs. The N. chromatus - Two Classic Tarantulas 17.12.2023

In this episode, we compare two very similar species: the A. geniculata or "Brazilian Black and White" and the N. chromatus or "Brazilian Red and White." Both are awesome species and, in my opinion, hobby staples. But which has more to offer?

The GBB vs. The Brazilian Blue Beauty 10.12.2023

First, I have an important message from the US Tarantula Sustainment Project . Then, we're going to have a little fun. In this episode, we'll compare and break down two species that are often confused for each other, the C. cyaneopubescens (GBB) and the D. diamantinensis (Brazilian Blue Beauty). Which spider is the "best"? Who knows! But we will attempt to find out! Be sure to...

Eresus walckenaeri Care and the Velvet/Jumping Spider "Fad" 26.11.2023

Having just rehoused my juvenile Eresus walckenaeri (Velvet Spider), I figured that it was time to talk a bit about how I care for it. Also in this episode, is the current Jumping Spider and Velvet Spider social media fad and rampant anthropomorphization leading to decline in overall appropriate husbandry in the spider hobby? I'll discuss what I feel are the realistic pros and cons of the att...

A History of Tom's Big Spiders and Why I Do This 12.11.2023

Last week, I had a few folks contact me a bit upset that there was no episode for Sunday.  And, to be honest, this happens every time I miss a week. Although I completely understand that this podcast has become very important to folks for a myriad of reasons, I thought that it might be a good time to explain why I do the Tom's Big Spiders stuff . In this episode, I'll go through the enti...

The Fastest Spiders That I Have Kept 29.10.2023

I've been asked to do this one many times over the years, but there is honestly no way for me to scientifically prove which ones are faster. However, in this episode, I will share the ones that I think are fastest based on my own personal experience.  What are YOUR fastest spiders? 

Is Your Enclosure and Setup Killing Your Juvenile Arboreal Tarantula? 22.10.2023

First, I read a listener question and talk about last week's episode. Then, I get a lot of emails and comments from panicked keepers who are alarmed to discover that their arboreal slings and juveniles are actually burrowing.  The fact is, MANY arboreal species will do some burrowing as slings and juveniles, and the correct setup should allow for and encourage this behavior. Unfortunately, ma...
