Accepted Answer

There are more than 800 recognized species of tarantulas, showcasing the diversity within this group of spiders.

Question 2

Male tarantulas have a lifespan of _____.&#10;A)less than six months&#10;B)one to two years&#10;C)between five and ten years&#10;D)up to thirty years

Accepted Answer

B

Question 3

Female tarantulas _____.&#10;A)have pedipalps that appear more swollen than in male tarantulas&#10;B)are known to have a lifespan that is less than six months&#10;C)have larger abdomens than male tarantulas&#10;D)develop spurs on the first pair of legs

Accepted Answer

Female tarantulas have larger abdomens than male tarantulas because they carry their eggs and may also store sperm in their bodies. Male tarantulas have more swollen pedipalps and develop spurs on their first pair of legs. Female tarantulas can live for several years, depending on the species.

Question 4

Adult tarantulas should be _____.&#10;A)offered food every other day&#10;B)fed daily or twice daily, depending on species&#10;C)housed with live insects for free-choice eating&#10;D)given pinkie mice daily and insects every other day

Accepted Answer

Adult tarantulas are generally less active and have slower metabolisms than juveniles, so they require less food. Offering food every other day is sufficient to maintain their health and nutrition. Overfeeding can lead to obesity and health problems.

Question 5

The largest tarantula has a leg span _____.&#10;A)that can exceed 12 inches&#10;B)that reaches a maximum of 8 inches&#10;C)of approximately 3 feet&#10;D)of more than 24 inches

Accepted Answer

The largest tarantula, the Goliath birdeater, can have a leg span that exceeds 12 inches. Therefore, option A is the best choice. Option D is incorrect as it states "more than 24 inches," which is not necessarily true for all tarantulas. Option C is incorrect as a leg span of three feet is much larger than any known tarantula. Option B is incorrect as it states the maximum leg span is only 8 inches, which is not true for the largest tarantula.

Question 6

Tarantulas have _____.&#10;A)three anatomical body divisions&#10;B)eight eyes clumped together&#10;C)one small claw at the end of every leg&#10;D)a closed circulatory system

Accepted Answer

Tarantulas are crepuscular, meaning they are most active during twilight hours at dawn and dusk. They typically spend their days hidden in their burrows or retreats and come out at night to hunt for prey.

Question 9

Breathing, or gas exchange, takes place in tissue called _____.&#10;A)setae&#10;B)chelicerae&#10;C)accordion lobes&#10;D)booklungs

Accepted Answer

Gas exchange in arachnids such as spiders and scorpions takes place in specialized respiratory organs called booklungs. Setae are bristle-like structures used for locomotion and sensory purposes. Chelicerae are mouthparts used for feeding. Accordion lobes are not a known structure in arachnids.

Question 10
