Questions & Answers

Q: How do sperm whales hunt colossal squid in the ocean?

Sperm whales use echolocation to track and capture colossal squid, leaving distinctive suction scars on their bodies from these battles. The squid put up a fierce fight despite being prey.

Q: What defensive adaptations do squid possess to evade predators?

Squid have evolved large eyes for detecting predators, chromatophores for camouflage, ink production for distraction, and jet propulsion for rapid escape, showcasing their sophisticated survival strategies in the ocean.

Q: How do squid use their chromatophores for camouflage?
