Fish

Biologists think pufferfish, developed their famous "inflatability" because their slow, somewhat clumsy swimming style makes them vulnerable to predators. In lieu of escape, pufferfish use their highly elastic stomachs and the ability to quickly ingest huge amounts of water (and even air when necessary) to turn themselves into a virtually inedible ball several times their normal size. Some species also have spines on their skin to make them even less palatable.

A predator that manages to snag a puffer before it inflates won't feel lucky for long. Almost all pufferfish contain tetrodotoxin, a substance that makes them foul tasting and often lethal to fish. To humans, tetrodotoxin is deadly, up to 1,200 times more poisonous than cyanide. There is enough toxin in one pufferfish to kill 30 adult humans, and there is no known antidote.

However, some predators, such as tiger sharks and sea snakes, are unbothered by the pufferfish's natural toxins.

nothing, they dont drink O.O guessing they drink water xD

Yes, you and your mother. www.hoax-slayer.com/broken-bow-gar.shtml

Janitor fish can be used as an organic fertilizer in the form of a liquid emulsifier for crops like corn and tomatoes. The nutrients found in this fertilizer are nitrogen, phosphorus, and potassium. It can also have other uses as animal feed, biodiesel, and food. The janitor fish is an invasive species of catfish that is native to the Amazon River.

salt water shrimp contain more iodine than fresh water shrimp

All fish have a body covering of scales.

if you are going for fishing it is recommended that you buy a complete fishing set.

But, I recommend live bait like earthworms.

If it is in an aquarium I suggest that you buy a fishing net whose size depends on the size of the fish you are breeding.

fish move by swimming.they move their fins back and forth to swim.some fishes have a swim bladderwhich is an organ that help bony fish to stay in different deapth.

They just know. there brains are wired to know. its like a magnet.

Mormons are permitted to eat shrimp. If they do or not depends more on their personal taste. Mormons do not have many food restrictions. They are taught moderation. Their main restrictions are from tea and coffee. Many believe it is due to the caffeine. They are also not religiously permitted to use tobacco products or alcoholic beverages.

The Atlantic wolffish (Anarhichas lupus), also known as the Seawolf, Atlantic catfish, ocean catfish, wolf eel (the common name for its Pacific relative), or sea cat, is a marine fish, the largest of the wolffish family Anarhichadidae. They are commonly sighted throughout Asia. The numbers of the Atlantic wolffish are rapidly depleting due to overfishing and by-catch, and is currently a Species of Concern according to the National Oceanic and Atmospheric Administration's (NOAA) National Marine Fisheries Service (NMFS). Although it looks fearsome, the Atlantic wolffish is only a threat to humans when defending itself out of the water. Apart from their unique appearance wolffish are distinguished by the natural antifreeze they produce to keep their blood moving fluidly in their very cold habitat, involvement by both the male and female in brood bearing, and the large size of their eggs. They are also an important factor in controlling green crab and sea urchin populations, which can become overly disruptive to habitats if left unchecked. Wolffish population success is also an important indicator of the health of other bottom dweller populations, such as cod.

Underwater plants increase the oxygen level in the water and also act as fodder for the fish.

Most doctors agree that fish oil can be taken at any age, just in smaller amounts as years old. For example, they have fish oil for kids 7 and under in most pharmecutical stores, but I recommend 500 mg or less if adult fish oil pills in kids. Anything over 500 is save for adults. Or so I hear.

Many doctors recommend pregnant mothers take fish oil supplements especially in the second and third trimester. It is recommended that your child is at least one year old before taking fish oil supplement. Studies show that fish oil supports cognitive development. Children taking fish oil supplements have scored better test results than those who do not. Dosage differs with age so ask your family physician about the dosage for your child. If your child is over 12 years old, you may want to try Triple Strength Omega 3 which contains a pharmaceutical grade fish oil offer a purity of above 90 percent.

i think they eat plants or other little fish.

yes fish live in lakes they live in fresh water and salt water

Theoretically, yes, but be careful. I put a 6cm commit with my eastern long necked tortoise but my tortoise just followed it around for hours fascinated with it and attempting to eat it. Even though i have many small (2-4 cm) fish in the tank for her to eat.

Swim bladders are a relatively recent adaptation. Other kinds of marine animals have found different solutions to the same problem. Elasmobranchs have an oily liver, plankton continually swim up or have spines/ floats to avoid sinking, mammals have their airfilled lungs.

Oregon state university says if its preasure canned correctly it should be used within one year for maximum flavor and nutritive quality.

yes it is

Salmon comes from the countries bordering the north Pacific and north Atlantic oceans. The salmon spornes in rivers systems but lives its adult life in these Oceans.

Most members of the Piranha family, very likely eat human flesh. Plenty of anecdotal and real evidence on the Internet.

In USA terms, there is also a very real possibility, that the Northern Snakehead fish will, and has been known, to attack humans, inflicting quite serious injury.

Most documented cases, have involved people trying to 'scoop-up' young Snakeheads for possible use in a home aquarium. Huge mistake!! The parent fish is known to be incredibly protective of it's 'family' and will attack at any opportunity it is given!

This fish also has frogs and rats on its 'menu' so a few 'dangled fingers' in the water will make a tempting snack!

A symbiotic relationship is an association that is mutually beneficial. Wrasse fish feed on the parasites found on the black sea bass's body. In this case, Wrasse gets to eat, and sea bass gets rid of parasites. It's a Win-Win.

Both i guess...but anyhow since fish are cold blooded their body temperature could adjust to external environmental temperatures,so at times they "take-in heat energy" and at other times "give-out heat energy".

There are several but the commonest one I can think of is the Pelican.
