Mackerel sharks are thought to have been around for some 120 million years.

The following habitats are found across the Mackerel sharks distribution range.

Mackerel sharks may also refer specifically to the family Lamnidae.

They are commonly referred to as the mackerel sharks.

It had anatomical features similar to the current mackerel sharks of the family Lamnidae.

However, tuna and mackerel sharks are warm-blooded: they can regulate their body temperature.

This species is thought to be ovoviviparous with oophagous embryos like other mackerel sharks.

The upper and lower lobes on the tail fin are approximately the same size which is similar to some mackerel sharks.

The mackerel sharks (Lamnidae family) have a similar homologous structure to this which is more extensively developed.

Like other mackerel sharks, common threshers are aplacental viviparous.

Mackerel sharks boast among their numbers both the harmless filter feeders and a few very fearsome predators.

No pregnant smalltooth sand tigers have ever been found; this species is presumed to be ovoviviparous as in other mackerel sharks.

Lamnidae is a family of sharks, commonly known as mackerel sharks or white sharks.

Isurus is a genus of fast-swimming mackerel sharks, better known as the mako shark.

Unlike in mackerel sharks, the eggs consumed by the embryos are large and shelled rather than small and undeveloped.

Intrauterine cannibalism is common in the viviparous shark order Lamniformes (commonly known as mackerel sharks).

Lamniformes is an order of sharks commonly known as mackerel sharks (which may also refer specifically to the family Lamnidae).

Along with all other mackerel sharks, the pelagic thresher exhibits ovoviviparity and usually gives birth to litters of two.

Mackerel sharks (Lamniformes)

Like other mackerel sharks, bigeye threshers are ovoviviparous and bear litters of two pups, one in each uterus.

Order Lamniformes (mackerel sharks)

It has almost the same size upper and lower lobes on the tail fin (like most mackerel sharks, but unlike most other sharks).

The most extreme case of proximity is found in the mackerel sharks (Lamniformes), where the offspring feed on trophic eggs in utero.

Alternately, analysis based on dentition suggests that the closest relatives of the crocodile shark are the thresher sharks, followed by the mackerel sharks.

Like the false catshark, the slender smooth-hound exhibits aplacental viviparity with oophagy, in a form different from that in the mackerel sharks.

Anacoracidae is an extinct shark family in the order Lamniformes.

The order Lamniformes includes seven families, with a total of sixteen living species:

Lamniformes There are seven families in this order.

Otodontidae is an extinct family of sharks, belonging to the order Lamniformes.

It is the only member of the family Cetorhinidae, part of the mackerel shark order Lamniformes.

Hexanchiformes to Lamniformes.

Intrauterine cannibalism is common in the viviparous shark order Lamniformes (commonly known as mackerel sharks).

As with other Lamniformes shark species, salmon sharks are oophagous, with embryos feeding on the ova produced by the mother.

Order Lamniformes (mackerel sharks)

Phylogenetic studies based on morphology have generally placed the goblin shark as the most basal member of the order Lamniformes, known as mackerel sharks.

The teeth are numerous, relatively small, with a curved crown and serrated, up to 2.5 - 3 cm in height (the only representative of the Mesozoic Lamniformes with teeth).

The Lamniformes contains the extinct Megalodon (Carcharodon megalodon), which like most extinct sharks is only known by the teeth (the only bone in these cartilaginous fishes, and therefore are often the only fossils produced).

Mackerel sharks are thought to have been around for some 120 million years.

All species of mackerel shark give birth to live young.

The following habitats are found across the Mackerel sharks distribution range.

They are commonly referred to as the mackerel sharks.

Mackerel sharks may also refer specifically to the family Lamnidae.

However, tuna and mackerel sharks are warm-blooded: they can regulate their body temperature.

It had anatomical features similar to the current mackerel sharks of the family Lamnidae.

Mitsukurina is a genus of mackerel shark in the family Mitsukurinidae.

This species is thought to be ovoviviparous with oophagous embryos like other mackerel sharks.

Reproduction is probably viviparous with oophagous embryos like in other mackerel shark species.

Like other mackerel sharks, common threshers are aplacental viviparous.

The mackerel sharks (Lamnidae family) have a similar homologous structure to this which is more extensively developed.

The upper and lower lobes on the tail fin are approximately the same size which is similar to some mackerel sharks.

Isurus is a genus of fast-swimming mackerel sharks, better known as the mako shark.

It is the only member of the family Cetorhinidae, part of the mackerel shark order Lamniformes.

In 2010, Greenpeace International added the shortfin mako shark (Isurus oxyrinchus) to its seafood red list.

These are the common shortfin mako shark (Isurus oxyrinchus) and the rare longfin mako shark (Isurus paucus).

In 1809, Constantine Rafinesque first described shortfin mako and coined the name Isurus oxyrinchus (Isurus means "the same tail", oxyrinchus means "pointy snout").

In 2010, Greenpeace International added the shortfin mako shark (Isurus oxyrinchus or mackerel shark) to its seafood red list, "a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."
