Titan beetle (Titanus giganteus)

Titan is a giant deity in Greek mythology. As its name indicates, the adult Titan beelte can grow up to 16.7 cm long. It is one of the most mysterious creatures in the world. What interest scientists is that its larvae have never been seen so far. One issue of National Geographic published a full page picture of its larva, but was later proved to be the larva of the Macrodontia cervicornis. The mandibles of adult Titan beelte can easily break a pencil. They have strong legs and sharp claws. However, this large insect will usually not attack humans. As adults, they don't even eat much. They fly around to look for mates with the energy accumulated during larval stage and are easily attracted by the bright light in the dark.
