- "These howlers make good target practice, eh, Jaden?"
- ―Rosh Penin
Howlers were predators which lived on the moon Yavin 4. They got their name from their method of attack, which was a howl loud enough to stun their prey. Howlers were somewhat reptilian in appearance. They usually crawled on all four limbs, but sometimes when charging, leaping, and clawing, they used two legs for mobility.
