Asian Forest Scorpion


ORDER: Scorpiones

FAMILY: Scorpionidae

GENUS: Heterometrus

SPECIES: longimanus

DESCRIPTION:
H. longimanus is dark brown to black in color and is 3.5 to 5 inches in size. Scorpions have pincers, eight legs and a long tail with a stinger at the tip. Males have broader pincers and longer tails than females. They have two eyes in the center of their head and two to five along the margin on each side.

GEOGRAPHICAL RANGE AND HABITAT:
Tropical rain forest of southeast Asia. Found under logs and other debris.

DIET:
Insects and spiders.

LIFE CYCLE/SOCIAL STRUCTURE:
Nocturnal. Terrestrial, but will burrow to some extent. In courtship the male leads the female back and forth with his pincers. He then deposits a package of spermatozoa on the ground and pulls the female over it. She picks up the capsule with an organ on her abdomen. Young ride on the mother's back until they molt for the first time. They then become independent and live a solitary life. Life span is 7-8 years.

SPECIAL ADAPTATIONS:
They do not see well and depend on touch, using the stiff hairs on their pincers and pectines, a pair of comb-like structures underneath the last two legs.

INTERPRETIVE INFORMATION:
Scorpion venom is a neurotoxin used to paralyze prey. Scorpions sting humans in self defense. Most stings are not serious for humans but a couple of North American species can cause severe pain (Arizona) and even deaths (Mexico). Antivenins are available for these.

OUR ANIMALS:
One in the Children's Zoo. It came from the Chaffee Zoo in Fresno.

STATUS IN WILD:
Not endangered.
