ANGEL SHARK: Flat body like a stingray -- you can tell the shark is not a ray because the pectoral fins are not attached to the head. They bury themselves in the sand or mud with only the eyes and part of the top of the body exposed. They are bottom feeders, eating crustaceans like clams and mollusks and fish that are swimming close to the ocean floor
second largest shark (about 30 feet long and 8,000 pounds) filters plankton from the water using "gill rakers"
does well in captivity so is often found in aquariums (which is why we have so many photos of it) about 6 feet long. grey with a black tip on its fins and white streak on its side
about 12 feet long. sleek, tapered body among the fastest swimming sharks and can even leap out of the water diet consists mostly of squid, but it will eat almost anything considered dangerous - have attacked people
third most dangerous to people can swim in salt and fresh water and have even been found in the Mississipi river.
small, gentle shark that can be kept in an aquarium with other fish tail is half its length
biggest shark and biggest fish it isnt a whale (whales are mammals, not fish) grow to 45 feet long and 30,000 pounds, but average about 25 feet long filters plankton from the water using "gill rakers"
10 foot tail (1/2 as long as the body) which it uses to herd small fish
fastest swimmer (43 miles per hour) known to leap out of the water (sometimes into boats)
unlikely to attack people, but considered dangerous due to its predatory nature and its size eyes and nostrils are far apart, giving it a "hammerhead" appearance and allowing the shark to extend the range of its senses.
more attacks on people than any other type. averages 12 feet long and 3,000 pounds. unlike most sharks, it can lift its head out of the water.
very uncommon and likely the strangest looking shark (rarely seen the photos were actually taken in 1909) pale, pinkish grey skin with a long pointed snout (it looks a bit like a sword on top of its head) lives in very deep water.
a small shark (less than 2 feet long) eats perfecty round chunks out of living whales and dolphins by clamping its teeth extremely sharp teeth onto them.
The largest shark known was theMegalodon (Carcharodon or Carcharoclesmegalodon); it is now extinct. It was anancient, meat-eating shark that livedbetween 25 million and 1.6 million yearsago. It was up to 40 feet (12 m) long andits teeth were each the size of a personshand!
Dwarf Lanternfish (Etmopterus perryi), which is about 7 1/2 to 8 inches (19 - 20 cm) long for fully- grown females and 6 to 7 inches (16 - 17.5 cm) long for adult males Spined pygmy shark (Squaliolus laticaudus), which is about 8 inches (21 cm) long for fully-grown females and 7 inches (18 cm) long for males Pygmy ribbontail catshark (Eridacnis radcliffei) , which is about 6 to 7 inches (15 - 16 cm) long for fully-grown females and 7 to 7 1/2 inches (18 - 19 cm) long for males.
The oceanic white-tipped sharks are the mostfearless predators. Jacques-Yves Cousteausays that it is: "the only species of shark thatis never frightened by the approach of adiver, and they are the most dangerous of allsharks."
The fastest swimming sharks are the makosharks and blue sharks, which can evenleap out of the water. They are also amongthe fastest fish. Estimates of their speedvaries; some say that they can swim atabout 60 miles per hour (97 kph), whilemore conservative estimates are about 22mph (35 kph). There hasnt been enoughobservation of their speeds to have adefinitive answer.
The whale shark has the biggest mouthamong sharks.
The thresher sharks have the longest tailamong sharks; the upper lobe of their tailsare about the same length as their bodies.
The strongest shark bite belongs to thedusky shark (Carcharhinus obscurus); itsjaws have been measured to exert 132pounds (60 kg) of force per tooth (JamesSnodgrass and Perry Gilbert, 1965).
The piked dogfish shark (Squalusacanthias) is very abundant, especially inthe North Atlantic Ocean. It is a smallshark, about 63 inches (1.6 m) long.
The whale shark was long thought to beoviparous (an egg 14 inches (36 cm) longwas found in the Gulf of Mexico in 1953;this would be the largest egg in the world).Recently, pregnant females have beenfound containing hundreds of pups. Whalesharks are viviparous, giving birth to liveyoung. Newborns are over 2 feet (60 cm)long.
The Portuguese shark dives down over9,000 feet (2750 m). This is over 1.5 miles.
The Blue shark had been known tomigrate from 1,200-1,700 miles (2000-3000 km) in a seasonal journey from NewYork state in the USA to Brazil.
One Blue shark was found with 135 pupsin her uterus.
