Vegreville egg
The Vegreville egg is a giant sculpture of a pysanka, a Ukrainian-style Easter egg. The work by Paul Maxum Sembaliuk is built of an intricate set of two-dimensional anodized aluminum tiles in the shape of congruent equilateral triangles and star-shaped hexagons, fashioned over an aluminum framework. The egg is long and three and a half stories high, weighing in at . It is the second largest pysanka in the world. The biggest one was built in Kolomyia, Ukraine in 2000.
Kassina fusca
"Kassina fusca" have been found in nests of pomerine ants "Paltothyreus tarsatus" and "Megaponera analis". These ants are large (up to 18 and 25 mm in body length, respectively) and have powerful mandibles, poison glands, and stings, and would be able to kill the frog. Yet experiments showed that they were never seriously attacked by "Paltothyreus tarsatus". This is possible because of chemical components of the frogs' skin, offering the frog a degree of "chemical camouflage". The benefit of this association is that the ant nests provide "Kassina fusca" hiding places that remain moist during the dry season; such places are in short supply in the savanna and tend to be occupied by ants. Another species showing a similar association is "Phrynomantis microps".
