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.
Dwarf pufferfish have dark, iridescent patches on their flanks and dorsal surfaces. The maximum documented size is 3.5 cm (1.4 in) total length (TL), [9] with individuals typically reaching less than 2.5 cm (0.98 in) TL, [5] making dwarf pufferfish one of the smallest pufferfish in the world.
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]
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.
A row of large brownish black spots extends from the chin to the caudal-fin base on the lower sides, separate from the dark dorsal color. Many tan, fleshy tabs are present near the rear of the body. At only 18 cm, the reported maximum size for S. spengleri is much less than that of the checkered puffer.
Canthigaster rostrata, commonly known as the Caribbean sharp-nose puffer, is a pufferfish from the Western Central Atlantic. The Caribbean sharp-nose puffer is a small fish with a maximum length of 12 cm or approximately 4.7 inches. [ 2 ]
