Photo of the day (28): juvenile orange Tylomelania

I found this one orange juvenile Tylomelania snail in my aquarium on January 23, 2014.

juvenile orange TylomelaniaI do not know how exactly old it could be. The width of the shell was 5.0 mm and the height of the shell was 10.5 mm on February 2, 2014.

Other snails in my aquarium are as follows: many Gyraulus crista, many Bithynia tentaculata, one Neritina pulligera, one adult orange Tylomelania. Therefore I know, that the one adult Tylomelania is a female. It is good to know, because the gender of Tylomelania snails can be usually identified according to the snail size. Females are larger.
