Some American soldiers serving in Iraq have become infected with a skin disease caused by a protist called Leishmania, which is transmitted by sand flies. The Leishmania organism bears flagella with a unique crystalline rod structure. One of its life stages is squiggly and worm-like in appearance, much like its relative in the same group, Trypanosoma. Leishmania belongs to the group .

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
