Description

#Polymorphic

Size: 6cm
LD50: 1.45 mg/kg

Mesobuthus eupeus is a polymorphic scorpion species belongs to the well-known family Buthidae. Commonly known as the lesser Asian scorpion or the mottled scorpion. It is thought to be the most widely dispersed species of the genus Mesobuthus, perhaps even of the family Buthidae.

M. eupeus can reach a size of 4 to 5 centimetres in length. The entire body is yellow to yellowish brown. The dorsal segments of the mesosoma often have longitudinal irregular stripes that are black to dark brown. They exhibit sexual dimorphism, the adult females being generally larger than males but have a lower number of pectinal teeth (16 to 23, as opposed to 22 to 28 in males). The pedipalps of M. eupeus have a maximum of ten diagonal rows of granules on the fixed finger and eleven on the movable finger. The pedipalp chelae (pincers) are wider than the patella (segment IV). The segments of the metasoma are thick and have eight keels (octocarinate). The telson is subglobose with a flat dorsal surface.

Polymorphism, in biology, means a discontinuous genetic variation resulting in the occurrence of several different forms (morph) or types of individuals among the members of a single species. A discontinuous genetic variation divides the individuals of a population into two or more sharply distinct forms.

ABOUT SIZES

Scorpions usually sell by instar, a developmental stage between each moult.

However for pricing convenience, this is a personal GENERAL guideline.

1. Scorpling: i2 to i3
2. Juvenile: i3 to i4
3. Sub-adult: i4 to i5
4. Adult: i5 and above
