What is a shrew?

You might call a mouse small, but a tiny creature knows and a shrew may be much smaller.  In fact, shrews are among the tiniest mammals on earth.

Shrew are furry animals that look much like a mice, except for their long, pointed noses, which they use to explore cracks and crevices for food.

Shrew

Some kinds of shrews are only two to three inches long and weight about as much as a penny, while the largest ones may be the size of small rats.

Shrews make their homes in grassy fields, woodlands, gardens and marshes.  They are often mistaken for mice because of their small size.

But for all its small size, a shrew is a big eater and spends almost all its life in a never-ending hunt for food.

It must eat nearly twice its own weight in insects and worms each day to keep up its supply of energy.

Shrews are useful in gardens and farms.  They get rid of pests that destroy drops.– Dick Rogers

 

What is a sea lamprey?

Sea Lamprey

A sea lamprey (pronounced LAM pree) is an eel-like water creature.  It grows up to three feet long.  Its mouth is a cuplike sucker lined with sharp “teeth”.

Fishermen dread the sea lamprey because of its destructive eating habits.  It is a parasite—it eats other fish by attacking itself to the other fish with its strong sucker mouth.

It scrapes a hole in the fish with its teeth and tongue, which also has teeth, and then sucks the blood out of the fish.

A fish attacked by a sea lamprey usually will die.

Sea lampreys are normally saltwater creatures, but they swim up freshwater rivers and into lakes to spawn.

Sometimes they remain in the inland lakes and never go back to the sea.

When this happens, they can become serious pests.  Sea lampreys have destroyed many important food fishes, such as trout and mackerel, in the Great Lakes.-  Dick Rogers
