True clams, in the strict sense, are bivalves with equal shells closed by two adductor muscles, and with a powerful, muscular, foot that they use to burrow themselves in the mud
The word is often applied only to those that are edible, spending most of their lives partially buried in the sand of the ocean floor
Clams live in both salt water and fresh water.
Clam needs to open their valves if they move about, and also to allow their two feeding tubes (siphons) to reach out into the water. Bivalves feed by filter microscopic algae out of the water they live in.
Clams can be found in a variety of sizes ranging from 0.004 of an inch to almost 4 feet as seen in the giant clam
Some clams have life cycles of only one year, while at least one may be over 500 years old
Clams age can be calculated by counting rings on its shell. The growth-increments themselves provide a record of how the animal has varied in its growth-rate from year to year, and that varies according to climate, seawater temperature, and food supply.
A medium-sized, heavily furred mammal. Thick neck, broad shoulders with short powerful legs, sharp teeth, and claws.
They are found living in the forests of Europe and western Asia
The most commonly known badgers are the white and black striped badgers in western Europe. They have black faces with distinctive white markings, grey bodies with a light-coloured stripe from head to tail, and dark legs with light-coloured underbellies. They grow to around 90 cm (35 in) in length including tail.
The behaviour of badgers differs by family, but all shelter underground, living in burrows called setts, which may be very extensive.
Badgers prefer dry, open grasslands, though they are very adaptable. Some also live in the woods, quarries, hedgerows, sea cliffs, and moorland.
These highly social animals have distinct social groups, typically of four to six adults
Badgers can run at 25–30 km/h (16–19 mph) for short periods of time.
The diet of the badger consists largely of earthworms, insects, grubs, and the eggs and young of ground-nesting birds. They also eat small mammals, amphibians and reptiles, as well as roots and fruit
