"Umbrella Crab" (Cryptolithodes sitchensis)
Also known as the Sitka crab or the Turtle Crab, the umbrella crab is a species of lithodid crab that is native to coastal regions of the northeastern Pacific, ranging from Sitka, Alaska to Point Loma, California. C. sitchensis is noted for having a unusual half-moon shaped carapace that extends over its walking legs and chelipeds, this serves as a form of camouflage allowing C. sitchensis to blend in with the rocks around it. The color of C. sitchensis’s carapace is highly variable and often matches the color of the coralline algae with C. sitchensis feeds on.
Please Stop Feeding Bread to Waterfowl
Feeding bread to wild ducks is incredibly harmful. Bread has almost no nutrients that are useful for the duck, so they become malnourished and more susceptible to disease. Compounding the problem is that excessive bread left in the water will rot, which leads to high levels of E. coli and even botulism outbreaks. Wild ducks need to stay wild, and artificially feeding them causes them to lose their natural instincts for acquiring food.
If you want to feed captive waterfowl, consider chopped vegetables, whole grains, or fruit instead.

Lepidophyma flavimaculatum (Yellow-spotted tropical night lizard) is a medium-sized night lizard (family Xantusiidae) that inhabits the Atlantic versants of the tropical forest in Central America and Mexico. It lives under logs or rocks. It preys on small arthropods, like flies and centipedes. It has a flat body and head, and its black skin is covered with yellow spots. Like all night lizards, it gives live birth to its young and its eyes are covered by a transparent membrane, similar to that in snakes. Its behavior is characteristically secretive, but it is known to be aggressive when handled.
