Splendid toadfish
The splendid toadfish, also referred to as the coral toadfish, is a vibrantly colored fish found in the waters around the Isle of Cozumel, Mexico. This species is notable for its striking appearance, featuring a blend of blue, black, and magenta hues with bright yellow borders on its fins. Typically measuring between four to six inches in length, splendid toadfish are small compared to other toadfish, yet their vivid colors make them stand out in their rocky cave habitats, which lie at depths of 30 to 80 feet (10 to 25 meters).
As bottom-dwellers, splendid toadfish utilize their long dorsal fins for balance and rounded pectoral fins for navigation. They are carnivorous, primarily feeding on smaller fish and crustaceans, and are known for their aggressive behavior towards prey, aided by their sharp teeth. Though their mating habits are not well-documented, spawning occurs when females release eggs that males subsequently fertilize. The eggs attach to surfaces in rock cavities and various debris, with males guarding them during their incubation period of about three weeks.
Despite their resilience, splendid toadfish face threats from larger predators, pollution, and human activities, which have led to their classification as endangered by the IUCN Red List. Their ability to survive in low-oxygen environments and for hours outside of water adds an intriguing aspect to their biology.

Coral toadfish
Splendid toadfish, also known as the coral toadfish, are much more colorful than many other species of toadfish. Their bodies are decorated in blue, black, and magenta, a shade of purplish pink, with bright-yellow borders along their fins. While splendid toadfish are recognized for their bright colors, they are not known for their size.

Splendid toadfish inhabit the waters around the Isle of Cozumel, Mexico. They are generally found in rocky caves in about 30 to 80 feet (10 to 25 meters) of water. As bottom-dwellers, they are well-suited to this environment.
Growing to a length between four and six inches (10 to 15 centimeters), splendid toadfish are rather small compared to other toadfish, but with brightly colored bodies, they stand out among their larger, more blandly colored relatives. Splendid toadfish may range in color from dark brown to magenta, a shade of purplish pink. Across the heads and necks, run many tan to yellow lines and across their backs and sides many gray patches. In addition to their colorful bodies, splendid toadfish also have colorful fins. All of their fins are bordered in bright yellow. Their long dorsal fins, which run the lengths of their backs, help splendid toadfish keep their balance, while their caudal, or tail, fins help them steer through the water. Splendid toadfish also have large, rounded, pectoral fins, on their sides, as well as smaller pelvic fins beneath their necks. These fins help splendid toadfish push through the water. In addition to their many fins, splendid toadfish also have small, fleshy projections dangling from their chins.
Like other fish, splendid toadfish need oxygen to survive. Unlike humans, splendid toadfish cannot breathe oxygen through the air. Instead, they use the oxygen which is in the water. Splendid toadfish take water into their mouths, use the oxygen they need, and release the waste chemicals out through their gills. One interesting thing about toadfish is that they are able to survive on very little oxygen for a long time. They are even able to survive outside of water for several hours.
Like other toadfish, splendid toadfish are carnivorous, meaning they live on a diet of mostly meat. They spend their lives hunting the ocean floor for such prey as smaller, bottom-dwelling fish and crustaceans. Splendid toadfish, like all toadfish, are known for their belligerent, or aggressive, nature towards other animals, especially their prey. With their mouths full of sharp teeth, splendid toadfish easily overcome their prey.
Mating season for splendid toadfish is not known. This process of spawning begins when female splendid toadfish release their eggs into the water. The males then fertilize those eggs. This process is called spawning. Once the eggs are fertilized, they float down and attach themselves to the surface of rock cavities, and different kinds of man-made products such as cans, pipes, and debris. Male splendid toadfish guard their broods, or groups of eggs, during the eggs' three-week incubation, or growth, period.
Generally, splendid toadfish are threatened by larger, fiercer sea creatures. They also suffer from pollution and hunting and trapping and are listed as endangered by the International Union for Conservation of Nature (IUCN) Red List.
The life span for splendid toadfish is not known.
