Hare vs Jackrabbit
Verdict: A jackrabbit is a hare, so there is no true split. Hares are born furry with open eyes, and jackrabbits add huge ears, long legs, and speeds up to 35 to 40 mph in open country.
Jackrabbits are not rabbits at all. They are hares, and the National Park Service says so directly. Early settlers called them jackass rabbits for their long ears, and the name was later shortened. So hare and jackrabbit are not opposite choices. That is why the two words overlap rather than compete.
This page compares what all hares share with what makes a jackrabbit, using the black-tailed jackrabbit as the example. The sources describe jackrabbits well, but do not cover every other hare, so the quiz can confirm jackrabbit traits and is cautious about the rest. Ears, tail, and habitat are the practical clues.
Hare vs Jackrabbit side by side
| Trait | Hare (the group) | Jackrabbit (black-tailed) |

| Weight | Varies by species | 4 to 8 lb, up to about 9 lb in Texas |
| Length | Varies by species | About 18 to 26 in |
| Ears | Long ears also help release heat | 4 to 7 in long with black tips |
| Tail | Varies by species | Dark stripe running along the top |
| Speed and leaps | Run to escape rather than hide | Up to 35 to 40 mph, leaps up to 20 ft |
| Habitat | Open areas | Open, flat, dry country with short grass, often nocturnal |
| Litters | Varies by species | Up to six litters a year, up to eight young each |

When you are looking at which
Hare (the group)
- You are asking what makes a hare different from a rabbit, since jackrabbits are one kind of hare.
- You found a newborn that is already furry with open eyes and hopping around.
- The animal escapes by running in zigzags across open ground rather than ducking into a burrow.
- You are reading about hares in general, not a specific species.
Jackrabbit (black-tailed)
- You see very long ears with black tips, around 4 to 7 inches.
- A dark stripe runs along the top of the tail.
- You are in open, dry, flat country with short grass, such as Texas or the Southwest.
- It bounded away at high speed, with leaps of 10 to 20 feet.
How this works
Because a jackrabbit is a hare, the quiz does not try to separate two different animals. It checks whether the cues match a black-tailed jackrabbit, and treats everything else as a hare or rabbit of unknown kind. Answer only what you saw, and choose I can't tell for the rest, since each skipped cue simply drops out of the result.
The sources describe the black-tailed jackrabbit best, so other jackrabbits, such as the white-tailed species, and other hares are not scored in detail. Check your state wildlife agency for ranges. A result that does not match a jackrabbit is not proof of another species, only that the jackrabbit cues are missing.
Where these numbers come from
The figures and defaults on this page are based on:
- National Park Service: Rabbits and Hares, Golden Spike NHP, Jackrabbits are hares, hares are born furry with eyes open. (checked October 2026)
- National Park Service: Black-tailed Jackrabbit, Big Bend, Ears, tail stripe, size, speed, leaps, and litters. (checked October 2026)
- Texas Parks and Wildlife Magazine: When Is a Rabbit Not a Rabbit?, Name origin, precocial young, size, speed, and ears as cooling system. (checked October 2026)
Field-identification guide. Wild hares should be observed from a distance, and local wildlife agencies can confirm species.
Frequently asked questions
Is a jackrabbit a hare or a rabbit?
A hare. The National Park Service states that jackrabbits are not really rabbits at all, but hares. The jackrabbit name comes from the older jackass rabbit, which referred to the very long ears.
How do hares differ from rabbits?
Hares are born with fur and open eyes and can hop soon after birth. Rabbits are born hairless and blind and need extended care from their mother.
How fast can a jackrabbit run?
Park and wildlife sources give up to 35 mph for black-tailed jackrabbits in Texas and up to 40 mph at Big Bend. They can also leap about 20 feet in one bound when frightened.
Why are a jackrabbit's ears so big?
The ears give excellent hearing and also work as a cooling system that releases body heat on hot days. Black-tailed jackrabbit ears are about 4 to 7 inches long.
