Nurse shark is about 1.03× longer by these reference values.
These animals are effectively close in maximum-length terms, so measurement uncertainty can matter more than the apparent difference. Lemon shark's weight reference is about 2.3× heavier.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.
THE NUMBERS
Side by side.
WHAT SETS THEM APART
More than a size contest.
Length and weight
Lemon shark is represented by commonly to 3 m / 10 ft; Nurse shark by recorded to 3.08 m / 10.1 ft. The values are upper-end figures, not a typical adult profile. Length is a recorded maximum; mass is a rounded adult reference.
Habitat and diet
Lemon shark: Shallow subtropical coasts and mangroves; fishes, rays and crustaceans. Nurse shark: Warm reefs, flats and mangroves; fishes, rays, mollusks and crustaceans.
Bite evidence
Lemon shark: No standardized maximum is available for a fair cross-species comparison. Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings.
Records are not averages
Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.
