Eastern Crayfish

Cambarus bartoni

Size: to 3"

Habitat: small streams, sometimes ponds and lakes

Notes: Active at night, hides in burrows or under objects during the day.

Compare freshwater crayfish with marine lobsters.

Blue coloration is the crayfish equivalent of albinism, and also occurs in lobsters. Individuals like this have little chance of surviving in the wild.

Overview of Algae & Plants

Algae and plants are similar in that they can produce their own food from nutrients and sunlight by photosynthesis. The main difference between the two is in their complexity. Algae are simple organisms, sometimes unicellular, and even the largest types are relatively simple in structure. True plants, on the other hand, are quite complex, with many specialized structures, even in the smallest types.

Fungi are not plants, they do not produce their own food, but rather feed upon decaying matter. But neither are they animals, so I tacked them on here.
