Ants find their way by emitting a gland-made smell trail. In a sandy environment where these trails would blow away, scientists believe “pedometer-like” cells in ants’ brains count steps. A group of ants were caught and divided into 3 groups: stilts added for longer legs, partial leg amputation for shorter legs and normal legs. When they were released, the ants on stilts walked past their nest, those with amputations stopped short of their nest and those with normal legs walked right to their nest. However, each group had taken the same number of steps. It seems ants have a “counterculture”.

Crows can recognize individual humans by their faces. To prove this, volunteers were asked to wear a cave man mask when they were catching and tagging crows. No matter who wore the mask, crows would fly near and caw loudly. When a different mask was worn, there was no crow response. However, when the cave man mask was worn upside down, some crows turned upside down in flight to get a better look at the mask. For thousands of years the survival of crows has depended on recognizing who would harm them – and thus they can recognize individuals in a “crow-d”.

Insects may become a major food source by 2050 when the earth’s population is billions larger and more “meat” is needed. This is the opinion of a Dutch entomologist. Insects make up 80% of the earth’s animals and 80% of earth’s people already eat insects intentionally. The rest of us eat them unintentionally. In the U.S. chocolate can have 60 insect components per 100 grams, peanut butter can have 30 insect parts per 100 grams and fruit juice can have 5 fruit fly eggs and 1-2 larvae for every 250 milliliters. This is information that could make some Americans “bug-eyed”.

Jellyfish – their size determines the number and length of their tentacles. The 40-pound “lion’s mane” jellyfish has a disk-shaped bell that can measure 3.2 feet across and tentacles that can extend more than 32 feet. The tentacles are in eight clusters with 150 tentacles in each. Like all jellyfish, their tentacles are covered with “nematocysts” – capsules containing a trigger and a stinging structure. One tentacle can have thousands of nematocysts, which are activated upon contact with an object. A dead jellyfish or even a detached tentacle can still sting. Obviously, these sea creatures are more Kamagra jelly dangerous than they “sea-m”.
