FLAKE FISH FOOD
This is the most common type of fish food that is fed to most pet fish. Flake fish food usually comes in a small container with a removable lid. The flakes are dry, and are designed to float on the top of a fishtank after being sprinkled in the water. Because of this, flake fish food formulas are best suited for fish species that prefer to feed on the top of the water. With a bit of research, you will be able to figure out if your fish are top-dwellers, mid-water dwellers or bottom feeders. However, many bottom-dwelling fish will still be able to eat flaked fish food after it settles on the bottom of the tank. Flaked fish food is baked at high temperatures, in order to remove moisture and to give it a much longer shelf life.
SHORT INFORMATION ABOUT SHARK AND THERE FEATURES
SHARK TEETH
Sharks have the most powerful
jaws on the planet. Unlike most animals' jaws, both the sharks' upper
and lower jaws move.
A shark bites with it's lower jaw
first and then its upper. It tosses its head back and forth to
tear loose a piece of meat which it swallows whole.

Each
type of shark has a different shaped tooth depending on their diet (the
shark in the photo is a great white -- you can tell he's a carnivore just
by looking at those sharp, pointy teeth!).
A shark may grow and use over 20,000
teeth in its lifetime!

DINNER TIME
Normally, sharks eat alone.
But sometimes one feeding shark attracts others. They swim up as
quickly as possible and all begin to try to get a piece of the prey.
They bite wildly at anything that gets in their way -- even each other.
The great white
shark rarely partakes in feeding frenzies.
SUPER SENSES
One of the reasons that sharks
are such successful predators is that they have such super senses.
Two-thirds of a shark's brain is
dedicated to its keenest sense -- smell.
Some sharks have eyes similar to
a cat. A mirror-like layer in their eyes allows them to see better
in the water. This allows the shark to hunt in clear seas or murky
water.
To top it off, sharks have a few
unusual senses. For instance, they are able to feel vibrations in
the water using a line of canals that go from its head to its tail.
Called a "lateral line", these canals are filled with water and
contain sensory cells with hairs growing out of them. These hairs
move when the water vibrates and alerts the shark to potential
prey.
Sharks also have a sensory organ
called the "ampullae of Lorenzini" which they use to
"feel" the electrical field coming from its prey.
SUCKER FISH
Sucker Fish, also known as Remora are fishes which are about thirty
centimetres long when fully grown. These fishes are capable of swimming
but are generally found attached to sharks, turtles, dolphins, and even
to ships. The first dorsal fin is modified into a suction apparatus; its
rays become divided into two halves and are modified into transverse
plates which are surrounded by a membranous fringe. Erection of the
plates after the fish joins its host creates a vacuum which enables the
fish to remain attached. The sucker fish cannot be dislodged until it
wishes to get detached.
