The Happy Face Spider

happy face spiderFound only on the islands of Oahu, Molokai, Maui, and Hawaii, the happy face spider, such as this one guarding its eggs on a leaf in Maui, is known for the unique patterns that decorate its pale abdomen. Scientists believe Theridion grallator may have developed its distinctive markings to discourage birds from eating it.

Can one be immortal?

hydra

The Hydra is a tiny animal that can be found in just about any freshwater pond, just a few millimeters long, that has attracted the attention of scientists for years now due to its extraordinary regenerative abilities. The Hydra is considered to be biologically immortal – it does not die from old age – although a scientific consensus has yet to be reached. Scientists studying the polyp Hydra claim they now know how the creature escapes senescence after they found a key gene. This gene is also believed to be linked with aging in humans.

The animal’s potential immortality is made possible by its reproductive system. The Hydra is an asexual being and doesn’t mate, instead it reproduces by producing buds in the body wall, which grow to be miniature adults and simply break away when they are mature. Popular scientific consensus has found that animals that reproduce later on and less frequently tend to live longer. The Hydra, however, begins to reproduce almost immediately.
