The largest tilefish is the great northern tilefish, or Lopholatillus chameleonticeps, which lives in the waters of the Atlantic Ocean and the Gulf of Mexico. They are small-sized marine fishes with habitats near coral reefs or the sandy regions in tropical or temperate waters. There are various tilefish species that have been categorized based on their appearance such as blackline tilefish, gray tilefish, rainbow tilefish, blueline tilefish, and blue head tilefish. These fishes have yellow and gold spots on their body and are ocean blue under the eyes.

Some species of the tilefish live in shallow waters while others live in deep-sea waters. Tilefish are opportunistic omnivores and mostly feed on crustaceans like crabs and shrimps. Other small fishes like mollusks, sea urchins and squids are also a part of their diet. Some tilefish have vibrant colors like pinkish blue-green, and yellow, while some have dull colors like grey and brown.

This fish species lives in burrows created at the bottom of the sea floor.

What class of animal does a tilefish belong to?

Tilefish is a fish belonging to a family of small fishes. The different species of tilefish are golden tilefish, great northern tilefish, purple tilefish and blueline tilefish. Golden tilefish species have a very long lifespan and can live for approximately 50 years. This species can be found in the waters from Florida to Nova Scotia.

How many tilefish are there in the world?

The conservation status of golden tilefish species is listed as Not Extinct, which means that their population is stable across Florida to Nova Scotia. But the great northern tilefish, one of the largest species of tilefish, is listed as Endangered on the IUCN red list. Their population is less than average and is continuously declining. Other species of tilefish are far from extinction and have a large population in shallow and deep waters.

Where does a tilefish live?

Golden tilefish can live in deep and shallow waters where the climatic condition is moderate or tropical. Great northern tilefishes dig burrows in the bottom of the ocean and can go into a state of hibernation. Golden tilefish are found on muddy slopes, open water bodies and sandy regions which allow them to burrow near the outer continental shelf.

What is a tilefish's habitat?

The habitat of a tilefish changes according to its species. Great northern tilefishes are usually found in deep waters, while others can be found in shallow waters of the outer continental shelf. Golden tilefish cannot survive in chilly waters and die when the water temperature decreases. Mass extinction of the great northern tilefish was observed when the climatic conditions changed, and the water became chilled.

Who do tilefish live with?

Most tilefish are solitary and dig their own burrows for hiding. Others are found in small groups, or pods. Tilefishes congregate during the mating period, and some have monogamous pairs. The purple tilefish is a fast swimmer and remains hidden during daylight.

The average lifespan of a golden tilefish is 50 years, but the females can live for 46 years. These fish are long-lived, slow-developing perciform fishes belonging to the class of ray-finned fishes. They live in tropical and temperate conditions and cannot survive in extreme weather conditions. Golden tilefish burrow holes in the sand and hide there for survival. The great northern tilefish also hibernates in the water. Change in weather, habitat degradation and overfishing are the main reasons that their population is declining.

How do they reproduce?

The breeding season in tilefish occurs between April to June when the climate is suitable for reproduction. The average female lays between two and eight million eggs during the spawning period. The rare pastel tilefish build rubble mounds, which are used as a refuge by other species. The pastel tilefish builds a school above this mound where they breed. The larvae are aquatic and drift as soon as they reach the juvenile stage. The larvae are not guarded or protected by the parents and are left to drift in the open stream.

What is their conservation status?

The conservation status of the tilefish ranges from Not Extinct to Endangered as per the species. The largest species of tilefish, the great northern tilefish, is listed as an Endangered species by the IUCN red list. The pastel tilefish is also a rare species of the malacanthidae. The reason behind their dwindling population is rampant overfishing and habitat loss. This species is covered under the Individual Fishing Quota program and Snapper Grouper Fishery Management Plan in an attempt to keep the overfishing at bay.
