4 What is it? Look at each sample and identify it. Be specific. (1pt each, 4pts total) 10. _ 11. _ 12. _ 13. _ 14. In the microscope, you will see two specimens of the same creature. It s a member of the Class Arachnida, and is related to spiders, ticks, and mites. They are tiny, 2 to 8 millimeters in length, with four pairs of legs and one pair of relatively large pedipalps (pincer-like claws). Most people do not notice or recognize them, which is primarily due to their secretive nature and small size. Frequently we discover them in bathroom sinks and tubs; however, they are neither dangerous nor destructive. They eat many small arthropods, including caterpillars, flies, ants, beetle larvae, and booklice. You may move the specimen card on the microscope stage in order to see both specimens, but please don t remove the card from the stage. What is this animal? (2pts) 15. Look at these egg specimens. Are these from a reptile or an amphibian, and why? (2pts) 16. Give two differences between horns and antlers. (2pts) 17.

7 25. Loons have four basic calls, though there are some variations. All calls are given by both males and females, except the yodel, a territorial call, that can only be produced by males. Listen to the CD, starting at track #1. Name the two loon calls (first 2 CD tracks) and then identify the other animal sounds on tracks #3- #6. (1pt each, 6pts total) Track #1 - The resembles a wolf howl. Individual loons use this call to locate other loons. If you listen closely, you will hear a wailing loon saying, Where are you? Indeed, that s what they are asking. Track #2 - The sounds like a quavering laugh. It is typically used when loons are disturbed. A variation of this call is the flight call. It is usually given over lakes and is a loon s way of requesting clearance for landing. If a loon on the lake responds with a yodel, the one in the air usually flies on to the next lake. Track #3 This is an omnivorous mammal that ranges throughout North America, and is the only representative of the family Procyonidae in Wisconsin. Track #4 This insect is well-known for producing a loud buzzing sound in the treetops during summertime. Track #5 This bird exclusively feeds on fish, and is also known as the fish hawk. It is found worldwide. Track #6 One of Wisconsin s most common nocturnal birds, it remains year-round and is generally found in dense woodlands often near waterways. Its name comes from the vertical streaking pattern of feathers on its chest. /6pts Running Total: 89pts 4/15/2016 FINAL VERSION Page 7 of 9
