Interpretation. 1  Opiates are the natural or synthetic drugs that have a morphine-like pharmacological action. 2  Heroin (diacetylmorphine) is a synthetic opiate made from morphine and is rarely detectable in body fluids. 3  Ingestion of bakery products containing poppy seeds can also cause morphine to be excreted in urine.
Western pond turtles are omnivorous and most of their animal diet includes insects, crayfish and other aquatic invertebrates. Fish, tadpoles, and frogs are eaten occasionally, and carrion is eaten when available. Plant foods include filamentous algae, lily pads, tule and cattail roots.
Mud (Kinosternon spp.) and musk (Sternotherus spp.) turtles are two common, hardy species that remain rather small. While most remain less than 5 inches in length, a few individuals may grow slightly larger. Mud and musk turtles are primarily aquatic, though they require a small land area on which they can bask. Mud and musk turtles are omnivorous, but they eat insects, fish, worms and carrion in the wild. A note about these relatively small turtles: they can make a pretty big stink. When these turtles feel threatened, they can release a musky odor.
