The species is commonly referred to as the giant freshwater pufferfish due to its massive size, growing to a length of 67 cm (26 inches). As such, these fish are difficult to adequately house in home aquaria since they require a very large tank and appropriately scaled water filtration.
The long-spine porcupinefish is pale in color with large black blotches and smaller black spots; these spots becoming fewer in number with age. It has many long, two-rooted depressible spines particularly on its head. The teeth of the two jaws are fused into a parrot-like "beak". Adults may reach 50 cm (20 in) in length. [3]
Dwarf pufferfish are a slow-swimming, [30] demersal (bottom-dwelling) species. [5] Unlike many pufferfish species, which are primarily solitary and potentially aggressive or territorial between conspecifics (members of the same species), [37] dwarf pufferfish are found in large shoals, occasionally consisting of hundreds of individuals.

The northern puffer, Sphoeroides maculatus, is a species in the family Tetraodontidae, or pufferfishes, found along the Atlantic coast of North America. [2] Unlike many other pufferfish species, the flesh of the northern puffer is not poisonous, although its viscera can contain poison, [1] [2] and high concentrations of toxins have been observed in the skin of Floridian populations.
It occurs at a depth range of 10 to 180 m (33 to 591 ft) over sandy or muddy bottoms and is a very large pufferfish, reaching 100 cm (39.4 inches) in total length. The species feeds on fish and shrimp and can be dangerously toxic if ingested. It is known to be oviparous. [2]
