紫色洋金花


今天我穿著我的紫色洋金花(Datura metel)的萬聖節裝扮上了一整天的課。念過植物學的人看得出來我是某種茄科植物。有些人猜錯,以為我是牽牛花(這個是另外一科的)。

Ethnobotany的老師愛死我的裝扮了。她猜是Brugmansia(木曼陀羅),我說不是,但非常接近了!經我一番提示,Brugmansia花往下開,什麼往上開?她終於猜對了。

植物分類學教授一看到我就說,"You are a Datura." 呵,薑還是老的辣!不過聽說今年只有兩個學生(包括我)萬聖節裝扮成植物,大家怎麼這麼不給教授面子?

Crayfish

My ecology class went on a field trip to sample invertebrates in Otter Creek. It was tons of fun! I got too excited with all the insect nymphs and larvae that we caught under the rocks. There were also many crayfish. It was my first time capturing crayfish with hands. I found they don't really pinch. It might be because the crayfish we caught were not very big.

The other species we found include mayfly, stonefly, caddisfly, dobsonfly, snail, and midges; they indicate that Otter Creek has good water. Well, too bad that we had to release them afterwards so I didn't have crayfish for dinner. I didn't have the chance to take a picture, so here's a picture from the Internet to show you what a crayfish looks like.
