- Easier - Most
people think of a shark as being a large, ferocious
fish that has sharp teeth and feeds on meat. But in
truth a shark can be one of over 370 different types
and range in size from the whale shark, the largest of
all fish that measure up to forty feet long, to the
smallest shark, the spined pygmy shark that only grow
to a length of about six inches.
- Harder -
Sharks are found in all types of oceans including the
arctic, but most are found in warm seas. Some prefer
the spacious ocean depths, others are found in coastal
waters, a few enter rivers and lakes that empty into
the sea, and one species found in India and Pakistan
lives only in freshwater rivers.
- Sharks are different from most other kinds of
fish. They have a unique boneless skeleton that is
composed of tough, elastic cartilage. Most sharks have
a rounded tough-skinned, streamlined shaped body,
somewhat like a torpedo. This helps them to swim.
Unlike most fish, sharks do not have a swim bladder.
Instead their oversized liver is filled with an oil
that is lighter-weight than water. This also aids
their swimming ability. Even so, most sharks must
constantly swim or their body would sink.
- Unlike fish which spawn millions of eggs, sharks
have relatively few young and those mature slowly.
Shark eggs are fertilized inside the female's body.
Among most species of sharks, the fertilized eggs are
hatched inside the female, and the pups are born
alive. However, about 40 shark species do lay their
eggs outside their bodies. Young shark pups are not
cared for by either parent, and their greatest threat
is being eaten by a larger shark.

Trailhead at Virtual Field Trips
- Did you know that about 80% of the shark species
have never attacked humans? Sharks are found in all
the oceans of the world, but there are only four
species that are considered dangerous: the great white
shark (known to most of us courtesy of the movie
"Jaws"), tiger shark, bull shark and oceanic whitetip
shark. Humans are not the preferred food of sharks
despite public hysteria and opinion to the contrary.
Research suggests it to be a case of mistaken
identity. Read about this and much more on this
