Crabs live in more different places than any other sea animal. They are found almost everywhere in the ocean, including smoking volcanic vents thousands of feet below the surface. They also live under the ice in Antarctica. One type of crab even lives on land and climbs trees.
While crabs do not have teeth inside their mouth, some crabs—such as the decorator and brown crabs—have teeth in their stomachs. These grind against one another when the stomach contracts to mash up food.
Interesting Shrimp Facts You May Not Have Known
Whether you’re a fan of shrimp or not, these shrimp facts will give you a new appreciation for these little crustaceans. Just to clear the air–because believe it or not, some people truly don’t realize this–but shrimps and “prawns” as they are referred to in some parts of the world, are essentially the same thing. The only true difference between shrimp and prawns is that a prawn’s second abdominal flap rests on top of the first and third flaps. Crayfish is another term you might have heard associated with shrimp, but again, it is simply another name for members of the shrimp family! Let’s move on to our collection of shrimp facts…
It is estimated that there are over 300 different species of shrimp in existence, and each one has its own flavor and texture. The flavor and texture of a shrimp mainly depends upon what type of foods the shrimp eats and what kind of water it lives in. Even the color of a shrimp can be affected by the shrimp’s diet. For instance, the black and blue tiger shrimps, which have stripes of their respective colors on their shells when they are raw, are colored this way because the foods they eat do not contain any iron. And white shrimp aren’t actually white–they are grey when raw but turn a nice shade of pink once they have been cooked.
In just four ounces of shrimp, there is an estimated 1.22 grams of fat, 112.27 grams of calories, 220 grams of cholesterol, and .37 grams of omega-3 fatty acids. But that’s not all! Shrimp is an excellent source of folate and B vitamins, vitamins A, D, E, potassium, iron, calcium, and magnesium. They are also relatively high in sodium. Even though shrimp does tend to be high in cholesterol, they are low in calories as well as fat, which means they can be quite the lean addition to one’s diet. It has been said that eating shrimp on a regular basis can help prevent the development of conditions such as circulation disorders, high blood pressure, Alzheimer’s disease, and depression.
