In the anatomy of some taxa, such as many Cicadomorpha, the front of the head is fairly clearly distinguished and tends to be broad and sub-vertical; that median area commonly is taken to be the frons. [9] The clypeus is a sclerite between the face and labrum, which is dorsally separated from the frons by the frontoclypeal suture in primitive ...
The head of a small white butterfly (Pieris rapae). Note the upward pointing labial palpi on both sides of the coiled proboscis. Comparison of moth and butterfly dorsal anatomy. Adult Essex skipper (Thymelicus lineola) Pupa of a sphingid moth Caterpillar of the subfamily Arctiinae Eggs of the buff-tip (Phalera bucephala), a notodontid moth
This result suggests that the bottom-up cues that drive the flicking response are distinct from the top-down cues that drive the Hollow-Face illusion. Another example of the Hollow-Face illusion is the "Gathering 4 Gardner" dragon. This dragon's head seems to follow the viewer's eyes everywhere (even up or down), when lighting, perspective and ...
The broad whitefish is a herring-shaped fish with a more compressed body and convex head than other whitefishes. It is iridescent, with a dark olive-brown back, silvery grey sides, and a whitish bottom. [2] [3] Features that distinguish it from other species include a mild overbite and 18–25 short gill rakers.
John Landis Mason, inventor of the Mason jar. In 1858, a Vineland, New Jersey tinsmith named John Landis Mason (1832–1902) invented and patented a screw threaded glass jar or bottle that became known as the Mason jar (U.S. Patent No. 22,186.) [1] [2] From 1857, when it was first patented, to the present, Mason jars have had hundreds of variations in shape and cap design. [8]
Photo of a pileus or mushroom cap. In mycology (the branch of biology that includes the study of mushrooms and other fungi), the pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp (fungal fruiting body) that supports a spore-bearing surface, the hymenium. [1]
A demo of Graham's scan to find a 2D convex hull. Graham's scan is a method of finding the convex hull of a finite set of points in the plane with time complexity O(n log n). It is named after Ronald Graham, who published the original algorithm in 1972. [1] The algorithm finds all vertices of the convex hull ordered along its boundary.
