For one of the most remarcable anomalies among ants see http://myrmecos.net/2010/12/03/ant-freaks-of-nature/ .

[font=Times New Roman]Hi Marc, [/font]

[font=Times New Roman]Thanks fort the link! It is most surprising that this twin-ant was able to do ordinary work, carry leaf fragments, as Alex writes![/font]
[font=Times New Roman]Here are some of „my“ most remarkable teratologies, among them a Temnothorax unifasciatus with 8 legs (fig. 1):[/font]

[font=Times New Roman]She was able to clean her right antenna with the additional left fore leg; also a remarkable example of neuronal coordination is such an exceptional individual! Though she was always running counter-clockwise circles. Perhaps the reason why I could find her within a nest.[/font]

Wow ,thats impressive!!
But when did the anomaly probably start:was it on the ant since it was born , or did it appear as egg ,larvae or pupae?

thanks

[font=Times New Roman]Such anomalies probably are induced already in the embryonic stage, within the egg. One quite reasonable explanation is that a worker in the nest may have a somewhat defective mandibular tooth, so that it can damage the developing embryo when the egg is handled and carried.[/font]

[font=Times New Roman]Here are two – bad – copies of similar duplications. One is a larva of Temnothorax fuentei with two front ends, from López & Ortuno 1992, the other a two-headed worker of Temnothorax parvulus, from Balazuc (1958).[/font]
