Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population. Since peripatric speciation resembles allopatric speciation,in that populations are isolated and prevented from exchanging genes,it can often be difficult to distinguish between them.,and peripatric speciation may be considered one type or model of allopatric speciation. The primary distinguishing characteristic of peripatric speciation is that one of the populations is much smaller than the other,as opposed to allopatric speciation,in which similarly-sized populations become separated. The terms peripatric and peripatry are often used in biogeography,referring to organisms whose ranges are closely adjacent but do not overlap,being separated where these organisms do not occur—for example on an oceanic island compared to the mainland. Such organisms are usually closely related;their distribution being the result of peripatric speciation.
Theridion grallator,also known as the Hawaiian happy-face spider,is a spider in the family Theridiidae that resides on the Hawaiian Islands. T. grallator gets its vernacular name of "Hawaiian happy-face spider" from the unique patterns superimposed on its abdomen,specifically those that resemble a smiley face. T. grallator is particularly notable because of its wide range of polymorphisms that may be studied to allow a better understanding of evolutionary mechanisms. In addition to the variety of color polymorphisms present,T. grallator demonstrates the interesting quality of diet-induced color change,in which its appearance temporarily changes as it metabolizes various food items.
