![]() ![]() Their bodies are dark, which helps them blend in with their surroundings. They have large eyes and a long dorsal fin that helps them swim through the water. They are named for their distinctive method of hunting, which involves using a lure to attract prey.Īnglerfish are found in a variety of habitats, including reefs, swamps, and open water.Īnglerfish are adapted to live in the deep sea. The anglerfish is a unique creature that can be found in the deep waters of the ocean. Once the victim comes close enough, the anglerfish quickly opens its huge mouth, swallowing the hapless victim whole. Some species of anglerfish emit fluorescence from their lure. The lure (Illicium) is a modified spine that protrudes from the anglerfish’s head and dangles in front of its mouth. When hunting, the anglerfish uses its distinctive lure to attract prey. Their diet consists of small fish, crustaceans, and squid. For one, they are able to open their mouths extremely wide in order to consume large prey items.Īnother interesting fact about their feeding habits is that they use their lure to attract prey, which they then swallow whole.Īnglerfish are predators and usually hunt alone. The anglerfish is a unique creature that has some interesting feeding habits. Anglerfish Habits Anglerfish Feeding Habits When an unsuspecting victim comes close enough, the anglerfish opens its mouth rapidly, sucking the hapless victim into its gut. The first dorsal fin is usually modified into a lure known as an esca, which the fish uses to attract prey. However, some types of anglerfish can reach lengths of up to 39 inches (100 cm).Īnglerfish have a distinctive morphology, with large mouths and long, often filamentous dorsal fins. Anglerfish DescriptionĪnglerfish are a diverse group of fish that are named for their characteristic method of hunting and their unique appearanceĪnglerfish are generally small fish, with most species reaching lengths of less than 18 cm (7 in). This article will explore the different behaviors exhibited by anglerfish and what causes them. Status: The Tasseled anglerfish is currently not threatened and is not listed on the IUCN Red List.Anglerfish are also interesting in the way they mate, with the male anglerfish attaching itself to the female and relying on her for sustenance. It is often found living in rocky reefs covered with marine algae. Habitat/range: The Tasseled anglerfish is commonly found in the Southwest Pacific endemic to Australia. The female then completely covers the eggs with her side and guards them until they hatch and settle in crevices on the bottom. The female fans them vigorously in order to spread them out, while the male releases sperm. After she selects a mate, the eggs are rapidly released, each having filaments that adhere to rocks. Reproduction: Several males usually surround a female. Most anglerfish are able to rapidly change color and this is believed to communicate their mood. ![]() Anglerfish can expand their stomach and swallow food that is roughly two thirds their own size.Ĭommunication: Little is known about communication but visual cues are used. They use their “lure” to bring fish close to their extremely large mouth and then swallow them whole. ![]() Females are considerably larger than males.īehavior: Anglerfishes do not swim in the conventional way instead, they “walk” on their pectoral fins or use ‘jet propulsion’ (forcefully expelling water from a small opening generally behind and below the pectoral fins).ĭiet: Tasseled anglerfish are carnivores and feed on crabs, fish and even other anglerfish. Size: Most anglerfish of the family Antennariidae stay relatively small, reaching adult lengths of about eight inches (20 cm). In addition to their hairy tassles, their camouflage also includes warts and filaments on their skin, giving them an appearance similar to rough coral. Their thick spines are joined by transparent membranes. Eyes protrude from the head and have skin flaps. They are able to change their color to match their background. They are mostly bottom-dwelling fish, typically living in coral, up to a depth of 330 feet (100 m), where they lie in wait for prey. The lure consists of the illicium (the spine) and the esca (the bait), and may resemble a worm, crustacean, or small fish. The first dorsal spine is modified as a fishing lure to attract prey. ![]() They can be distinguished from other anglerfish by the three extended dorsal fin spines on their heads. Description: Tasseled anglerfish resemble a mass of seaweed rolling about the coral reefs. ![]()
