Shortfin Mako Shark Essay, Research Paper
The shortfin mako shark is the fastest fish in the universe. It is
capable of achieving velocities of up to 60 miles per hour. It s dark ruddy iron-rich
musculuss on the side of the shark s organic structure and particularly on the tail
enable the shark to swim at these velocities. The velocity of the mako
affects its physical features, its eating wonts, and its marauders.
The mean size of the shortfin mako shark is from 10 to 12 pess
and the largest size of all time recorded was 18 pess.
This fish weighs about
1,000 lbs. Its big heavy conico-cylindrical molded organic structure is
colored in such a manner that it blends into the openwater environment
doing them unseeable to feed. Its dorsum is a deep blue grey and its
underparts are snow white. The neb of this shark is bluffly pointed ;
this helps the shark to rush through the H2O. Its first dorsal five,
which is short starts behind the thoracic fives.
This is unusual
compared to other sharks in the mako shark s household. The anal five is
bantam compared to the dorsal five. The mako has long gill slits and
strong caudal keels. The upper and lower lobes of the caudal five are
of about equal length. The mako has big eyes and is considered
one of the most beautiful common sharks.
The mako shark is found worldwide in temperate and tropical
seas. It is found from the Gulf of Maine to the equator and is most
dumbly populated in the Gulf of Mexico. These sharks are oceanic,
yet they are on occasion found inshore. They migrate seasonally
approximately 1,550 stat mis. In the summertime, mako sharks stay comparatively
near to the shore, approximately 20 stat mis out. In the winter they migrate into
well deeper Waterss. They do this so that they can be in H2O
warmed by the gulf watercourse.
The Isurus oxyrinchus has a two twelvemonth reproduction rhythm.
Though few have been seen copulating, scientists believe that the male
makos attack the females and coerce them to copulate. They believe this
because frequently times females are found with atrocious hurts to the
dorsal and thoracic fives following coupling. Gestation takes about 12
& lt ;< br />
months and reproduction is ovoviviparous. This means that the
female parent carries the eggs internally until they are ready to hatch. While
in the uterus the embryos are oviphagous ( they feed on unfertilised
eggs ) . An mean litter consists of 10 to 12 whelps, each being about
two pess long.
The shortfin mako shark is a carnivorous animate being that feeds on
swordfish, tuna, mackerel, tuna, herring, Tarpon atlanticus, and other big fish.
Once a 120 lb swordfish was found whole, blade and all, in the
tummy of a 730 lb mako. Often times these sharks swallow
their prey whole. The long, thin, crisp dentition of the mako enable it to
catch its nimble quarry. They are smooth edged and turn in rows. The
foremost two rows are used for obtaining quarry, and the other multiple rows
are used to replace damaged of lost dentition. The astonishing velocity of this
fish besides helps it to catch its nutrient.
The mako shark s merely enemy is adult male. This fish is hunted for
athletics and used in merchandises such as the oriental daintiness, shark five
soup, and gristle pills. The mako shark is a large game fish because
of its velocity, size and the great battle it puts up when hooked. It can
leap 15 pess out of the H2O to liberate itself from the fisherman. Mako
sharks are unsafe and have attacked many worlds and little
H2O trades. Fisherman must be careful. Because the shark is
hunted so much and so frequently, some people worry about it going
endangered. There have been no corporate surveies on the mortality
or population kineticss of the mako shark, and no 1 knows how
many sharks there are in the universe. Though the mako shark has no
preservation position at this clip, the National Marine Fisheries Service
( NMFS ) presently manages this shark. The NMFS has reduced
gimmicks of the shark by commercial fishermen.
It seems all animate beings have at that place place in the ecosystem,
including the much feared mako shark. If athletics fishing continues and
the shark s population dwindles, the black effects would be felt
for all ; even adult male, which at times believes he is above nature and non a
portion of nature.
