This is the basic difference between Dioxyribose Sugar and Ribose Sugar. Both have rings of five carbon atoms , but a hydroxyl group present at the 2' position of carbon atom in case of Ribose while the 2' position of carbon in Dioxyribose is occupied by a hydrogen atom.

Snake wine is an alcoholic beverage produced by infusing whole snakes in rice wine or grain alcohol. The drink was first recorded to have been consumed in China during (c. 1040–770 BC) and believed in folklore to reinvigorate a person according to Traditional Chinese medicine. It can be found in China, Hong Kong, Taiwan, North Korea ,Goa ( India), Vietnam etc.
The snake venom proteins are unfolded by the ethanol and therefore the completed beverage is usually, but not always,safe to drink.

Here in this picture you observe water appearing as a ball on a colocasia leaf or any other hydrophobic surface, this phenomenon is known as the 'LOTUS EFFECT'
The lotus effect is named after the lotus plant, which has leaves that repel water due to the unique micro- and nano-scale architecture of its surface.
The surface of a colocasia leaf, like that of a lotus leaf, is covered with tiny bumps and waxy coatings that make it hydrophobic. These microscopic structures reduce the contact area between the water droplet and the leaf surface, causing the water droplet to bead up and roll off the surface easily. This effect is due to the combination of surface roughness and low surface energy, which prevents water from spreading out and sticking to the leaf. (Own collection and photography).

Red ghost crabs are semiterrestrial crabs of the subfamily Ocypodinae. They are common shore crabs in tropical and subtropical regions throughout the world, inhabiting deep burrows in the intertidal zone. They are generalist scavengers and predators of small animals. The name "ghost crab" derives from their nocturnality and their generally pale coloration. They are also sometimes called sand crabs, though the name refers to various other crabs that do not belong to the subfamily. ( Own collection and photography)
