Fish has always been an important source of protein for humans for a long time now, and the family Scombridae includes some of the world's most popular fish food choices.

Not only food but the family Scombridae also includes many species of sport fishes and also has the fastest high-speed swimming fish and the biggest bony fish in the family.

The family Scombridae also includes tunas, mackerels, and bonitos fishes which are collectively called Scombrids.

The family Scombridae consists of 51 species and two subfamilies. The subfamily Scombrinae has four genera (Scombrini, Scomberomorini, Sardini, and Thunnini) which are separated by the characteristic internal bones of the fishes.

This discovery was found and put on record and cited by Collette and Chao in 1975 and Collette and Russo in 1979. The classification of the family Scombridae is categorized by the mode of insertion of the caudal fin rays. The caudal fin here is divided strongly and has a slender, ridged base.

A family of fishes found in the tropical and temperate waters of the ocean, the fish in the family Scombridae possess considerable speed and some fishes are also partially endothermic. We will read further about the family Scombridae in the next topics.

Scombridae Interesting Facts

What type of animal is a Scombridae?

The family Scombridae is a family of fish that has four different genera.

What class of animal does a Scombridae belong to?

All the fish species of the family Scombridae falls under the class of Actinopterygii in the kingdom of Animalia.

How many Scombridaes are there in the world?

The total population of the mackerels, tunas, and bonitos is undefined. But 74% of the population has seen a decline between 1970-2010.

Where does a Scombridae live?

Scombrids are called the predators of the open ocean. They can be found worldwide in tropical and temperate waters of the ocean.

These fishes, tunas, and mackerels are found living in the open ocean in tropic and sub-tropical seas. Only a few travel to cold temperate waters in different seasons. Except for the smaller mackerels that usually stay near coastlines, the bigger mackerels roam the deeper waters.

Some of the species are found in brackish waters, but mostly these species are a marine family. The species of Thunnus maccoyii, Thunnus obesus, Thunnus alalunga, and Thunnus tonggol are found to carry out transoceanic migrations.

What is a Scombridae's habitat?

The species of mackerel fish and tunas are found all over the world in the seas of tropical and sub-tropical nature. All four genera of the tunas, mackerel, and bonitos are found all over the world where they are used as sport species and they are also a species that is extensively used as food.

Tuna is a great example of that and is used in many forms to be eaten.

Scombrids are generally predators in the marine world. Due to their highly streamlined body and retractable fins, they are very good at swimming and can attain high speeds. Tunas are endothermic which helps them to maintain high speed. They also have a large amount of red muscle, giving them endurance in the open seas.

Who does Scombridaes live with?

Some species are found near the surface, while the other ones are found in deep water and move about from one habitat to another. Tunas always come first when we talk about the family of Scombridae as they are widely found all over the world.

They are usually found in small schools. Some can be even found singly in the water.

How long does a Scombridae live?

The age of the family of Scombridae varies with each species. The Atlantic Bluefin tuna has a maximum age of 35-50 years, while the Southern Bluefin tuna lives up to 20-40 years.

The albacore tuna is known to survive for 9-13 years.

The Indian mackerel lives for just four years, while the Chub mackerel lives for 18 years. The life of the tuna and the mackerel also depends on the fish being the source of feeding millions of people all around the world, with a new population getting hunted every day.

How do they reproduce?

Except for the bluefin tuna, the Scombrids are known to spawn repeatedly. The Atlantic mackerel spawn the whole summer season. Some other mackerels are known to spawn from September to April. Half a million eggs are laid by the females of the mackerels. The eggs float near the surface of the water. Spanish mackerel breeds in and around April.

What is their conservation status?

Most of the species are categorized as Least Concern by the IUCN Red List. The small Albacore tuna however is kept as Near Threatened.

Pacific Sierra is a small mackerel and is kept as Least Concern at the moment, like most other mackerels. However, the constant hunting and killing of fish all over the world can lead to scarcity very soon.

Scombridae Fun Facts

What does Scombridaes look like?

Scombrids have slender, streamlined bodies with large mouths and well-developed teeth. The body is colored silver, blue, and metallic and features tiny cycloid scales on the surface.

The dorsal fin has 9-27 densely packed rays, while the pelvic fins have six rays. The first dorsal fin and the pelvic fins retract into body grooves. Dorsal fins slot into grooves in the body to reduce drag while swimming.

The caudal peduncle has two keels at least to reduce drag in the water and also accelerate water flowing over the tail. Most species are pretty large and have red muscle which is buried centrally along the spinal column to conserve heat.

All four genera are made of wet, slimy scales in the body. Bodies of the genera are made of small to moderate scales. The area behind the head and around the pectoral fins are covered with moderately large, thick scales.

The fast-swimming mackerel fish and the tuna fish are known for their high-speed swimming in the ocean which have elongated and streamlined bodies. They have a series of finlets behind their dorsal fin and the anal fin. The tunas and the mackerels also have a slender caudal peduncle. Also, both species have a crescent-shaped lunate tail.

Did you know...

Under the family Scombridae, adaptive radiation has been said to be a part of evolutionary change. Scombrids are said to share a common ancestry with 14 other pelagic fish families in history.

Members of the 15 families are coastal and oceanic pelagic in their ecology with diverse forms of life, proving that these families, along with the Scombrids, represent undetected adaptive radiation in the pelagic world, which brought a Scombridae evolution change. The Scombridae phylogenetic tree elaborates on this classification further.

The yellowfin Tuna, a part of the Scombrids, are found to do high-speed swimming at 14 mph.

Are they dangerous?

No, this family of fish is not dangerous.

Do humans eat them?

Mostly all the species of the family of Scombridae are used as food all over the world.
