Shortfin Mako Shark - Isurus oxyrinchus
The shortfin mako shark /ˈmɑːkoʊ/ (Isurus oxyrinchus), also known as the blue pointer or bonito shark, is a large mackerel shark. It is commonly referred to as the mako shark, as is the longfin mako shark (Isurus paucus).[1][2][3] The shortfin mako is on record as the fastest-swimming shark, capable of bursts of speed up to 18.8 metres per second (68 km/h; 42 mph).[4] The species is classified as Endangered by the IUCN.
The shortfin mako shark is a fairly large species of shark. Growth rates appear to be somewhat accelerated in comparison to other species in the lamnid family.[10] An average adult specimen measures around 3.2 m (10 ft) in length and weighs from 60–135 kg (132–298 lb). The species is sexually dimorphic, with females typically larger than males. Large specimens are known, with a few large, mature females exceeding a length of 3.8 m (12 ft) and a weight of 570 kg (1,260 lb).[10] The largest taken on hook-and-line was 600 kg (1,300 lb), caught off the coast of California on June 3, 2013,[11] and the longest verified length was 4.45 m (14.6 ft) caught off the Mediterranean coast of France in September 1973. A specimen caught off the coast of Italy and examined in an Italian fish market in 1881 was reported to weigh an extraordinary 1,000 kg (2,200 lb) at a length of 4 m (13 ft).[12] Yet another fish was caught off Marmaris, Turkey in the late 1950's at an estimated size of between 5.77 m (18.9 ft) and 6.19 m (20.3 ft) making it the largest known specimen of the species.[13] However, this estimate was created using photos of the shark and not at the time of capture so this estimate must be taken with reasonable caution. The authors did not estimate a weight for this specimen.
Atlantic Blue Marlin - Makaira nigricans
The Atlantic blue marlin (Makaira nigricans) is a species of marlin endemic to the Atlantic Ocean. It is closely related to, and usually considered conspecific with, the Indo-Pacific blue marlin, then simply called blue marlin. Some authorities still consider both species distinct.
The Atlantic blue marlin (hereafter, blue marlin) feeds on a wide variety of organisms near the surface. It uses its bill to stun, injure, or kill while knifing through a school of fish or other prey, then returns to eat the injured or stunned fish. Marlin is a popular game fish. The relatively high fat content of its meat makes it commercially valuable in certain markets. It is the national fish of the Commonwealth of the Bahamas and is featured on its coat of arms.
Blue marlin are distributed throughout the tropical and subtropical waters of the Atlantic Ocean. A bluewater fish that spends the majority of its life in the open sea far from land,[2] the blue marlin preys on a wide variety of marine organisms, mostly near the surface, often using its bill to stun or injure its prey.
Females can grow up to four times the weight of males. The maximum published weight is 818 kg (1,803 lb) and length 5 m (16.4 ft).[3] Greater lengths have been claimed unofficially.[4]
The biggest females are more than four times as heavy as the biggest males, which rarely exceed 160 kg (350 lb) in weight.[13] The longest females can reach a length of 5 m (16 ft) with the bill, from eye to tip, constituting about 20% of the total body length.
Body mass in the largest female specimens has been reported from 540 to 820 kg (1,190 to 1,810 lb), depending on the source (few large specimens are scientifically verified).[14] The largest blue marlin caught by IGFA angling rules is from Vitoria, Brazil, which weighed 1,402 lb (636 kg).;[15] fishermen often refer to individual marlins that reach or exceed 1,000 pounds as "granders".
