Ais forAnchovy

Scientific name: family: engraulidae
Anchovies are small, oily fish that are usually preserved in brine and matured. This process gives them a very strong flavour. Anchovies are used on pizza, on Caesar salad and as an ingredient in numerous other dishes. They are one of the main ingredients of Worcestershire Sauce.
Anglerfish are small, predatory fish. They have one or more long, thin, flexible spines on their heads with a fleshy lump at the end. They can move this spine around and dangle the lump like bait in front of their mouths. Anglerfish are fairly rare and have an unusual way of reproducing. Male anglerfish are much smaller than females, and when they are mature they bite onto a female and then wither away to nothing but reproductive organs. They live like parasites on the female's bloodstream.

Fis forFish

Fish live underwater, in either salt or fresh water. They can only breathe underwater, but they use gills to breathe, not lungs like we do. Fish are covered in scales. Some people keep very small fish in their houses as pets. The biggest kind of fish is a whale shark, which is just a really big kind of shark. Whales grow a lot bigger than sharks but they are not fish, as they don't have gills and have to come to the surface of the water to breathe, just like we do.

Fis forFlounder

Scientific name: families: pleuronectidae and bothidae
Flounder is a common name for a large number of related flat fish species that typically live on the bottom of the sea where they camouflage with the sea bed. They eat smaller fish, catching them by surprise as their prey simply cannot see them.
Flying fish are a type of fish with very big fins. They can jump out of the water to get away from things that want to eat them, and then they glide through the air for some distance before they fall back into the water again. They can glide for around 50-400 metres, and reach speeds of up to 70km/h. Flying fish eat plankton, and are themselves eaten by tuna and dolphins.
