Leopard toadfish
The leopard toadfish, known for its striking blotched and striped markings resembling those of a leopard, is a bottom-dwelling fish native to the Gulf of Mexico. Typically growing to about 15 inches (38 centimeters), its coloration ranges from yellowish to buff with dark brown patterns that create an irregular design across its scaleless skin. This species possesses rounded pectoral fins and fleshy chin tabs that aid in movement through the water. Unlike some fish, leopard toadfish are active hunters, primarily feeding on fish and crustaceans with their large mouths equipped with sharp teeth. They can thrive in low-oxygen environments and have the ability to survive outside of water for several hours. Mating involves females releasing eggs into the water, which are then fertilized by males; these eggs attach to surfaces on the ocean floor and are guarded by the male until they hatch. While the specific lifespan of leopard toadfish remains unknown, they are often preyed upon by larger marine animals.

Leopard toadfish
Leopard toadfish were given the name leopard for their many blotched and striped markings. Native to the Gulf of Mexico, these toadfish are found on deeper reefs than gulf toadfish. They are called toadfish for their likeness to the squat, rough-skinned amphibians, the toads.

Leopard toadfish generally grow to be about 15 inches (38 centimeters) long. Their bodies are yellowish, buff, or straw-colored with darker brown markings. These markings are what give leopard toadfish the name leopard. Along their bodies the markings are blotches and patches, but on the tails they appear more as stripes and bars. In general, the markings form an irregular pattern across the fish's scaleless skin. In addition to their fins, leopard toadfish also have fleshy tabs along their chins. Like other toadfish, leopard toadfish have rounded, fan-like pectoral fins directly behind their heads, and smaller pelvic fins beneath their throats. These fins are all used to help leopard toadfish move themselves through the water. Leopard toadfish also have caudal, or tail, fins, which help propel them through water, and two dorsal, or back, fins which give them balance as they swim.
Like other fish, leopard toadfish need oxygen to survive. Since they cannot take it from the air, like humans, they must find the oxygen they need from their watery homes. Leopard toadfish take water into their mouths, use the oxygen in the water, and then push the waste chemicals out through their gills. Like other toadfish, leopard toadfish are able to live in water with very little oxygen for a long time. They are even able to survive outside of water for several hours.
Leopard toadfish inhabit many of the deep, rocky reefs in the Gulf of Mexico. They are generally found on deeper reefs than gulf toadfish. Like other toadfish, leopard toadfish are bottom-dwellers.
Leopard toadfish feed mainly on fish and crustaceans. This type of diet, focusing mostly on meat, causes leopard toadfish to be classified as carnivores, or meat-eaters. Their large, wide mouths are filled with sharp teeth that can easily devour prey. Unlike frogfish, which lure their prey, toadfish are active hunters. In fact, they even have a reputation for being belligerent, or aggressive, fish.
Mating season for leopard toadfish is not known. Spawning, or mating, begins when female leopard toadfish release their eggs into the water. The males then fertilize those eggs. This system of releasing and fertilizing eggs is known as spawning. After spawning, the eggs float down to the bottom of the Gulf and attach themselves to the surface of rock cavities, or different kinds of man-made products such as cans, pipes, and debris. Male leopard toadfish are known for guarding their broods, or groups of eggs, while the young are developing. Young leopard toadfish have an incubation, or growth, period of about three weeks.
Leopard toadfish are often preyed upon by larger, more powerful sea creatures.
The life span for leopard toadfish is not known.
