Bicephality in Eratigena atrica Larva
Teresa Napiórkowska* and Julita Templin
ABSTRACT
The study contains a detailed description of a larva of the Eratigena atrica spider, which had a well-developed prosoma and an additional, partly developed head with two segmented pedipalps and one chelicera with two fangs. The larva was obtained as a result of a teratological experiment based on the application of temperatures of 14 and 32°C changed every 12 h for the first ten days of spider embryogenesis.
