You can now report your live releases of shortfin mako sharks while still on the water.

They have been found with scars made by attacks from both white sharks and shortfin mako sharks.

Overfishing is occurring on the North Atlanitc shortfin mako shark population.

The attacks appear to be from more than one shark, and include at least one shortfin mako shark.

The shortfin mako shark is a yolk-sac ovoviviparous shark, giving birth to live young.

The shortfin mako shark (Isurus oxyrinchus-meaning "sharp nose") is a large mackerel shark.

It voted to limit the catch of several types of hammerhead sharks and to require countries to keep data on shortfin mako sharks.

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

In keeping with the name, the streamlining, pointed snout, and other detailing was partly inspired by the sleek, fast-moving shortfin mako shark.

Shortfin mako shark (Isurus oxyrinchus)

An uncommon species, it is commonly lumped together under the name "mako" with its better-known relative, the shortfin mako shark (I. oxyrinchus).

Members of the family Lamnidae (such as the shortfin mako shark and the great white shark) are homeothermic and maintain a higher body temperature than the surrounding water.

The shortfin mako shark is one of the rare sea creatures big enough and fast enough to chase down and kill an adult swordfish, but they don't always win.

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

Shortfin mako sharks are known to feed on adult cobia and have been seen by fishermen following cobia during their annual springtime migration in the northern Gulf of Mexico.

By releasing shortfin mako sharks that are unintentionally caught or caught for sport, U.S. fishermen will be leaders in encouraging fishermen from other nations to conserve this shark species.

In 2010, the Convention on Migratory Species (CMS) also added the shortfin mako shark to Annex I of its Migratory Sharks MoU.

The catch and release reports submitted via email allow fishermen to put their mako on the Shortfin Mako Shark Live Release Interactive Web Map at http://www.nmfs.noaa.gov/sfa/hms/shortfinmako/Map/index.htm.

By submitting this live release information through the app, and putting their mako on the map, fishermen will be able to see how they are making a difference in the conservation of shortfin mako sharks and encourage others to do the same.

Common threshers are well regarded by sports fishers as one of the strongest fighting sharks alongside the shortfin mako shark (Isurus oxyrhinchus), and are ranked as game fish by the International Game Fish Association (IGFA).

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."

While meeting three sharks in an old minefield on a fish-free diet at a meeting, Bruce, a great white shark; Anchor, a scalloped hammerhead; and Chum, a shortfin mako shark, Marlin discovers the diver's mask that was dropped from the boat and notices an address written on it.

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

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.

Mackerel shark - several species

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

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

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

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

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

Lamniformes - mackerel sharks

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

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

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").
