Giant Antarctic Sea Spiders | SciShow Talk Show

The SciShow Talk Show features Art Woods discussing sea spiders, their anatomy, and research on their gigantism. The conversation covers their unique physiology, including organs in their legs and their evolutionary history. The show also compares sea spiders to tarantulas, highlighting differences in anatomy and behavior. The discussion includes insights into the challenges of studying these creatures in Antarctica and the ecological factors influencing their size.

Where are sea spiders typically found?

• Within scuba diving distance

• In deep ocean trenches

• In freshwater lakes

• On sandy beaches

What do sea spiders primarily feed on?

• Algae

• Soft-bodied animals

• Plankton

• Coral

What is a unique feature of sea spiders' anatomy?

• They have wings

• They have a single eye

• They can change color

• Their organs extend into their legs

What is the function of the proboscis in sea spiders?

• To swim faster

• To crush and ingest food

• To sense danger

• To attract mates

What is one hypothesis for the gigantism observed in sea spiders?

• Genetic mutations

• High oxygen levels in cold waters

• Abundance of food

• Lack of predators

What is a possible ecological reason for the large size of sea spiders?

• To attract mates

• To dominate other species

• To avoid predators

• To store energy during food scarcity

How are tarantulas different from sea spiders in terms of anatomy?

• Tarantulas have a large abdomen

• Tarantulas have gills

• Tarantulas have no legs

• Tarantulas have a single eye

What is the primary defense mechanism of tarantulas?

• Venomous bite

• Camouflage

• Kicking urticating bristles

• Loud hissing

How do tarantulas capture their prey?

• By setting traps

• By spinning webs

• By chasing them

• By injecting venom and waiting

What is the significance of the tarantula's molting process?

• It makes them more aggressive

• It changes their color

• It allows them to grow

• It helps them fly
