Maternal Care and Parent Hatchling interaction observed in Asian Forest Scorpion (Heterometrus scaber) in captivity.

Heterometrus scaber is one of the least studied scorpions under the genus Heterometrus. I found this adult female from inside the premises of Hill Palace while we were doing our 'Fauna of Hill Palace' faunal diversity study. The adult female was gravid when I found it and was placed in a well maintained terrarium. The specimen did react good in captivity and towards the end of may2010, the female was seen digging burrow into the loose sand and no longer used the wooden bamboo plank as its hide. She was rarely seen outside except while feeding.

The gestation period of Heterometrus species is 8-12 months (The Biology of Scorpions - Gary A. Polis) while some families exhibit lesser period. I have observed very complex maternal care and hatchling interaction and I believe this complex behavior is directly proportionate to its gestation period. Most of the scorpions, especially Heterometrus species give birth to live scorplings and towards the end of June2010, she gave birth to a litter of 36 scorplings (The Biology of Scorpions - Gary A. Polis). The adult female carried the scorplings on her back for several weeks until their first molt. 

Several interesting observations were made like,

• The adult female scanning the whole terrarium before she leave the scorplings for a walk outside.
• Scorplings feeding directly from the adult female's mouth. The female showed no aggression or resistance while the scorplings had their meal
• Cannibalistic behavior within the litter when a less matured or injured scorpling was eaten by others etc.

These are just a few behaviors that I've noted in Heterometrus scaber scorpions in captivity. There's a lot more coming up.
