Green bottle blue tarantula Lifespan Calculator

The green bottle blue tarantula lifespan is shorter than that of the classic slow-growing ground species: pet-care guides give females about 12–14 years and males about 3–4. Chromatopelma cyaneopubescens grows fast and changes colour as it does, so the calculator also shows its stage and moult rhythm at your GBB's age.

Quick answer

Pet-care guides give female green bottle blue tarantulas (Chromatopelma cyaneopubescens, the GBB) about 12–14 years and males about 3–4 years (PangoVet; Bantam.earth). We found no zoo or study figure, so treat these as estimates. GBBs are fast-growing (Wikipedia) and reach about 5–6 in across the legs; juveniles have pink legs and a black-and-red striped abdomen before turning blue (Lincoln Children's Zoo).

Green bottle blue tarantula lifespan

Be clear about the evidence first: unlike the Chilean rose or the curly hair, the green bottle blue has no zoo fact sheet or published study giving a lifespan. Lincoln Children's Zoo, an accredited zoo that keeps the species, describes its habitat and colours but gives no age. The figures in the calculator come from pet-care guides: PangoVet (a vet-reviewed pet-care site) gives females up to 14 years and males up to 4, and Bantam.earth gives females 12–14 and males about 4.

That makes the green bottle blue tarantula lifespan roughly 12–14 years for a female — still a long commitment — and a few years for a male. Searches for the greenbottle blue tarantula lifespan, the GBB tarantula lifespan or the Chromatopelma cyaneopubescens lifespan all lead to these same numbers; the spelling of "greenbottle" simply varies.

GBB lifespan compared with other popular tarantulas

{table("Green bottle blue lifespan compared with other species on this site", ["Species", "Females", "Males", "Basis"], [[f"{E(TS[x]['name'])}", ta_rng(*TS[x]['female']['life']), ta_rng(*TS[x]['male']['life']), {"zoo": "Zoo", "study": "Lab study", "pet-care": "Pet-care guides", "study-via-wiki": "Study (via Wikipedia)"}[TS[x]['quality']]] for x in ("gbb", "rose", "curly", "pinktoe")])}

The table puts the GBB in the middle: longer-lived than the tree-dwelling pink toe, shorter-lived than the slow-growing Chilean rose and curly hair. Keep in mind that the GBB row rests on pet-care guides, while the others come from zoos or studies, so the gap may be smaller or larger than it looks.

Why might GBBs live shorter lives?

No study has tested it, but the pattern matches what is known for other tarantulas: fast growth comes with an earlier finish. Among the species on this site, the slow growers (Brazilian black, Chilean rose, curly hair) reach about 20 years as females, while the fast-growing GBB and the tree-dwelling pink toe sit lower. Treat that as a pattern, not a rule.

Female vs male green bottle blue tarantula lifespan

Pet-care guides give male GBBs about 3–4 years in total. As with every tarantula, the end comes after the maturing moult: tarantula males in general live one to two years after it (Criscuolo et al. 2010). No GBB-specific maturity age has been published, so the calculator does not guess one.

In the calculator a 1-year-old immature male has used about 29% of the male average and a 2.5-year-old about 71%. Mark him as matured and the time left switches to the post-maturity range. For sexing a GBB from a moult, see the male vs female tarantula checklist.

Green bottle blue tarantula growth rate and size

The GBB growth rate is quick for a tarantula: Wikipedia describes the species as very active and fast-growing, one reason hobbyists like it. The Furry Critter Network care guide gives an adult leg span of about 5–6 in, with females a little larger and heavier-bodied than males.

In the wild, GBBs live in webbed burrows under bushes and among tree roots in the desert of northern Venezuela, with the entrance often extended into a funnel of silk (Wikipedia; Lincoln Children's Zoo). Lincoln Children's Zoo adds that a GBB will stay in the same burrow for life if left undisturbed — a hint that it prefers a settled home to frequent rehousing.

Care that helps a green bottle blue tarantula live longer

No zoo or veterinary source we could reach gives numeric humidity or temperature ranges for the GBB, so we don't quote any. What the sources do say points to a dry, webbed setup rather than a damp one:

  • Dry habitat: the species lives in desert scrub in northern Venezuela (Wikipedia; Lincoln Children's Zoo). Keep a water dish rather than soaking the substrate.
  • Room to web: GBBs build extensive webs on the ground with tunnel-like entrances (Lincoln Children's Zoo). Give it floor space and something to anchor silk to.
  • Ventilation: air exchange reduces mould in any tarantula enclosure (University of Kentucky).
  • Leave the web alone: a GBB keeps one burrow for life if undisturbed (Lincoln Children's Zoo), so avoid needless rehousing.
  • Quick and skittish: a fast spider is easily dropped; work low over a soft surface if you must move it.

Like most tarantulas from the Americas, GBBs can flick urticating hairs, and they can bite. If a moult goes wrong or the spider stops standing, look for an exotic vet who treats invertebrates.

How a GBB's colours change as it grows

The GBB's colour change with age is one of the most striking in the hobby, and it also helps you place a spider's age. Lincoln Children's Zoo describes juveniles as having pink legs with a black-and-red striped abdomen. Adults look completely different: metallic blue legs and a blue-green carapace (Wikipedia), with a bright orange abdomen (Josh's Frogs listing) — the colours behind the name "green bottle blue".

The switch happens gradually over several moults. A dealer listing describes three distinct colour patterns from spiderling to juvenile to adult (Josh's Frogs), and a keeper's moult log reports more orange on the abdomen and darker legs with each moult (keeper anecdote, Tom's Big Spiders). Sources disagree on exactly when adult colours are complete, so use colour as a rough guide:

  • Pink legs, striped abdomen: a young spider, most likely in its first year or so.
  • Mixed colours, blue appearing on the legs: a growing juvenile.
  • Full blue legs, green carapace, orange abdomen hairs: adult colours — but a male only shows he is mature through his hooks and palpal bulbs.

How this green bottle blue tarantula calculator works

% of lifespan used = age ÷ average for this species and sex × 100 · average years left = average − age

The shared tarantula table holds pet-care-guide figures for the GBB: females 12–14 years (average 13) and males 3–4 (average 3.5). A 1-year-old female has used about 8%, a 4-year-old about 31% and a 10-year-old about 77%.

Because no maturity age has been published, females over one year are shown as "juvenile or adult" — colour and size tell you more. The result labels the GBB figures as pet-care estimates, and the same inputs give the same numbers on the main tarantula lifespan calculator.

Frequently asked questions

How long do green bottle blue tarantulas live?

Pet-care guides give females about 12–14 years and males about 3–4 (PangoVet; Bantam.earth). No zoo or study figure exists.

What is the GBB tarantula lifespan for males?

About 3–4 years in total, ending one to two years after the maturing moult (pet-care guides; Criscuolo et al. 2010).

How fast do GBB tarantulas grow?

Fast for a tarantula — Wikipedia describes the species as very active and fast-growing.

How big do green bottle blue tarantulas get?

About 5–6 in leg span as adults, females a little larger (Furry Critter Network care guide).

When does a GBB get its blue colour?

Gradually over several moults. Juveniles have pink legs and a striped abdomen (Lincoln Children's Zoo); adults have blue legs, a blue-green carapace and an orange abdomen.

Where do green bottle blue tarantulas come from?

The desert scrub of northern Venezuela, where they live in webbed burrows under bushes and roots (Wikipedia; Lincoln Children's Zoo).

Do GBBs need high humidity?

No source we trust says so; their wild habitat is dry desert scrub. Keep a water dish and good ventilation rather than a wet enclosure.

Is Chromatopelma cyaneopubescens a good beginner tarantula?

It's hardy and colourful but fast and skittish, and it flicks hairs. It suits keepers who don't need to handle their spider.
