Yellow-shelled semi-slug (Parmarion martensi)

Janggel or yellow-shelled semi-slug (Parmarion martensi) is an animal species in Ariophantidae, semi-naked snails or has an internal shell which is very small, nocturnal but sometimes performs activities in the morning when the environment is wet, very moist and foggy.

P. martensi has a pair of antennas, a small and reduced shell wrapped in a mantle to form a bulge in the upper back to cover the head to half the body. The shell is brownish yellow, transparent, thin, shiny and shaped like a nail.

Dlium Yellow-shelled semi-slug (Parmarion martensi)

Yellow-shelled semi-slug has a length of 3-5 cm, yellowish brown or grayish brown or dark brown on the back. Two black parallel lines that extend from the base of the antenna on the head to the back of the body.

Janggel is found in andosol soils in mountainous and highland areas, tropical at an altitude of 750-3,000 m, pH 7, temperature 11-25C, humidity 80% and rainfall 2,500-7,000 mm/year.

P. martensi is often seen clustered with activities not far apart because of slow locomotion and move in a place not too far away. The eggs are often placed in groups with 10-15 eggs per group.

This species moves while secreting phlegm that is toxic to plants. They eat dead and living organic material including leaves, stems, flowers, fruit and other parts of plants that cause holes by bite marks on the surface. Sometimes it also takes root and shoots.

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...
