Questions & Answers

Q: How do crabeater seals use their strange teeth to survive?

Crabeater seals have interlocking lobes in their teeth that act as sieves to filter out tiny krill from mouthfuls of seawater, allowing them to feed on their primary food source.

Q: How do naked mole rats use their teeth in their daily activities?

Naked mole rats use their teeth not only for digging burrows and gnawing roots but also for moving their babies and carrying food.

Q: Why do the teeth of cookiecutter sharks grow in interconnecting rows?

Cookiecutter sharks have interlocking teeth that function as a unit to remove plugs of flesh from their prey. Their teeth are also replaced as a single unit, and the old teeth are swallowed to reabsorb calcium.

Q: How do moray eels catch their prey without using suction?

Moray eels rely on their powerful bite, enabled by their complex pharyngeal jaws and teeth, to catch their prey. They can launch their secondary jaws into their mouths to clamp down on their prey.

Summary & Key Takeaways

  • Crabeater seals have serrated teeth that act as sieves to filter krill out of mouthfuls of seawater, a crucial part of their diet.

  • Naked mole rats have two pairs of protruding incisors that they can move independently, and their teeth make up a significant portion of their musculature and brain function.

  • Cookiecutter sharks have interlocking teeth that they use to remove plugs of flesh from their prey, leaving behind cookie-sized wounds.

  • Moray eels have powerful pharyngeal jaws and teeth that they can launch into their mouths to catch larger prey.
