Above the shortfin mako shark
And down a longfin mako shark

There are to species of Mako sharks the shortfin mako and the longfin mako. So i will start with the shortfin mako shark

1. The shortfin mako grows to a length of 1.82–3.2 m (6–10 ft) and weights 60–400 kg (135-880 lb). The largest confirmed size was 3.96 m (13 ft) and 794 kg (1,750 lb). It has a bluish back and white underside.  Shortfin makos are known for their speed and their ability to leap out of the water. The shortfin mako shark is a sleek spindle-shaped shark with a long snout. This shark has short fins. It’s second dorsal fin is much smaller than the first. The apex of pectoral fin and first dorsal fin are rounded in younger makos. The teeth are slender and slightly curved.

2. The shortfin mako feeds mainly upon bony fishes, mackerels, tunas, bonitos, swordfish and sailfish, sometimes eat other sharks, porpoises, sea turtles, and seabirds. Makos swims deeper than the their prey so they have a good view of what is above and have a chance of seeing and attacking their prey before they are seen themselves.

3. The shortfin mako is most of the time found in warmer offshore waters and tropical seas worldwide. It species that can be found from the surface down to depths of 150 m (490 ft.). The shortfin mako is found in blue waters normally far from land. And sometimes closer to shore around islands.

4.The shortfin mako’s speed has been recorded at 50 km/h (31 mph) and there are reports that it can achieve bursts of up to 74 km/h (46 mph). It can jump up to 9 m (28 ft.) in the air. They do not know how long its lifespan is they think it lives to 12 to 24 years.

5. The shortfin mako shark gives birth to live young. Developing embryos feed on unfertilized eggs produced by the mother in the uterus. And gestation period is 15 to 18 months. The 4 to 18 surviving young are born live in the late winter and early spring at a length of about 70 cm. While a male shortfin mako need 4 1/2 to 5 years to reach 136 kg (2 m) and female reaches 227 kg (2.7 to 2.9 m) in 7 years when matured. It is believed shortfin makos travel long distances to seek food or to mate. One mako is known to swim 1,322 miles (2,128 km) in 37 days averages 36 miles (58 km) a day.

6. Between 1580 and 2007 the shortfin mako has had eight recorded unprovoked attacks on humans with two being fatal and twenty boat attacks.

And now some facts about the longfin mako shark

1. They believe that the longfin mako lives worldwide in tropical and warm-temperate oceans. They do not know because they get mistake for the shortfin mako. but they know it is found in the Atlantic Ocean and the Gulf Stream off the east coast of the United States, Cuba and southern Brazil in the west, and from the Iberian Peninsula to Ghana in the east possibly including the Mediterranean Sea and Cape Verde. In the Indian Ocean it has been reported from the Mozambique Channel. In the Pacific Ocean it occurs off Japan and Taiwan northeastern Australia a number of islands in the Central Pacific northeast of Micronesia and southern California.

2. The longfin mako is the larger of the two makos and the second-largest species in its family, growing to 2.5 m (8.2 ft) long and weighing over 70 kg (150 lb). Females are larger than males. The largest reported longfin mako was a 4.3 m (14 ft) long female caught with a long pointed snout and large eyes. There are 12–13 tooth rows on either side of the upper jaw and 11–13 tooth rows on either side of the lower jaw. The gill slits are long. The pectoral fins are as long or longer than the head with a nearly straight front margin and broadly tips. The first dorsal fin is large with a rounded apex and is placed behind the pectoral fins. The second dorsal and anal fins are tiny. The caudal peduncle is expanded laterally into strong keels. The caudal fin is crescent-shaped with a small notch near the tip of the upper lobe. The coloration is dark blue to grayish black above and white below. The unpaired fins are dark except for a white rear margin on the anal fin the pectoral and pelvic fins are dark above and white below with sharp gray posterior margins.  Off Cuba it is most frequently caught at a depth of 110–220 m (360–720 ft) and is rare at depths above 90 m (300 ft). Off New South Wales, Australia most catches occur at a depth of 50–190 m (160–620 ft) in areas with a surface temperature around 20–24 °C (68–75 °F).

4. The longfin mako is less active than the shortfin mako shark. For it’s diet it mainly has small bony fishes and squids. Adult longfin makos likely have no natural predators while young mako sharks may fall prey to larger sharks. The longfin mako gives birth to two pups at a time one inside each uterus. The pups measure 97–120 cm (3.2–3.9 ft) long at birth. It is suggested that during the winter females swim into shallow coastal waters to give birth. Male and female sharks reach sexual maturity at lengths of about 2 m (6.6 ft) and 2.5 m (8.2 ft).

5. They have been no attacks on humans from the longfin mako shark. But nevertheless it big size and it’s teeth make it a little bit dangerous.
