Largemouth vs. Spotted Bass Physical Differences

As we have seen above, both fish species are quite similar in appearance, but some physical differences might help you differentiate them from each other.

These differences may not be so distinct, especially for novice anglers, but they are significant for die-hard anglers.

The Jaw

The largemouth bass has a big mouth characterized by a large jaw, while the spotted Bass has a small mouth and a small jaw.

The jaw of the Largemouth extends past the rear of the eye. Nonetheless, the jaw of the Spotted Bass does not extend past the eye.


The color of the Largemouth bass is greenish-grey (on top), black (on the gill covers), and sometimes a combination of greenish-grey and silvery or blue on its sides.

In contrast, the Spotted Bass has a yellowish-green body color with dark olive to brown top. Like the Largemouth, spotted also have black spots on the top of its body.


As we have seen above, the Spotted Bass is smaller than Largemouth bass and can grow up to 25 inches, while the Largemouth bass can grow up to 30 inches.

Dorsal Fin

Both fish have two dorsal fins, but they are clearly connected in the Spotted Bass. But in Largemouth Bass, these fins are separated or almost separated.

Lateral Line

The lateral line of Spotted Bass is dark and spotted, while the lateral line of Largemouth bass is not spotted.

Largemouth bass doesn’t have a distinguished lateral line like the Spotted Bass.

Stomach Markers

Largemouth vs. Spotted Bass Behavioral Differences

Although both fish species are a carnivore, they are different when it comes to their behaviors.

  1. The largemouth bass is solitary fish. But, Spotted Bass are schooling fish that usually gather in large numbers often.
  2. Spotted Bass prefer clear water, but Largemouth bass can live in both clear and brackish water.
  3. Spotted Bass are more active all year than Largemouth, which requires slower presentations in the winter when they slow down.
  4. Largemouth Bass, when hooked, tend to leap out of the water in an attempt to break free. Spotted Bass, on the other hand, dive deeper into the water.

Largemouth vs. Spotted Bass Habitats

Bass species often share the same habitats in many freshwater habitats. But, both species clearly have their own preferences.

Largemouth Bass

The Largemouth Bass prefers clear or muddy water habitats with abundant vegetation cover for protection and its preferred prey, which includes crayfish, minnows, frogs, and mice.

You will often find these fish in murky waters than clear waters.

Largemouth Basses prefer temperate water conditions. So, they will often go to the deeper waters in the Winter season.

These fish often lurk around transition points where water is not too deep yet not too shallow. This is true, especially in the spawning season in the Spring.

Largemouth bass readily accepts vegetation as they provide necessary shelter. But, they rarely hide in submerged wood.

Spotted Bass

The Spotted Bass prefers clear or slightly turbid waters with moderate to no vegetation cover along with gravel or rubble bottom.

It is usually found in large rivers, but it also thrives in reservoirs and slow-moving freshwater streams. You may not locate them in natural lakes or ponds.

They don’t live in lakes and ponds because the water in these habitats is too murky. And Spotted Bass do not like murky waters.

Overall, you will find Spotted Bass anywhere in the USA where you will locate Largemouth Bass. This is perhaps, the main reason why anglers often get confused between these two species.

Fishing of Spotted Bass vs Largemouth Bass

As we said before, these popular game fish species often share the same habitats in the eastern and central United States waters but live on different water surfaces.

Spotted Bass prefer clear waters and usually stay within about 40 feet deep in their habitats. So, if you want to catch Spotted Bass, you will have to search around these areas.

On the other hand, Largemouths generally stay within shallow waters. They prefer vegetated areas with murky waters.

So, if you want to catch Largemouths, shallow water areas are the best places to start.

Largemouth Bass will hit large, bulky lures, while Spotted Bass prefer smaller lures. If you want to catch Spotted Bass, you will have to use lures that are 1/8 or less of an ounce.

Largemouth Basses can grow up to 20 pounds, but most caught fish weigh around 8-12 lbs on average. On the other hand, Spotted Bass only grow up to about 12 lbs.

The best season for largemouth bass fishing is the Spring when they are very active and often feed on their favorite food. The best season for Spotted Bass is in the Fall, when they start moving into shallower waters to spawn.

Bass fishing is so popular in the USA that you will find fishing equipment for each fish in every tackle shop.

The best time to catch these Bass is during the early Spring and late Fall seasons. But, you can still see them throughout the Summer.

The best time to catch Spotted Bass is around dusk, while Largemouths can be caught at any time.

While fishing, you must keep in mind that both species can be very aggressive during the spawning season in early Spring.

During this time, large males will fight each other to establish territory. So, it is best if you fish in small groups during this time to avoid any conflict.
