Which animal never sleep

No animal completely never sleeps, but some animals can go extremely long periods with little or unusual sleep. The animal most often said to “never sleep” is the Bullfrog. 🐸

🐸 Bullfrog
• Scientists once observed that bullfrogs do not show clear signs of sleep.
• Even when resting, they remain alert and responsive.
• Because of this, they were long believed to never sleep.

Other animals that sleep very little
• Giraffe – sleeps only about 2 hours a day. 🦒
• Dolphin – sleeps with one half of its brain at a time. 🐬
• Shark (some species) – must keep swimming, so they rest while moving. 🦈

✅ Conclusion:
Scientists believe all animals need some form of rest, but animals like the bullfrog appear to sleep very little or in ways that are hard to detect.
