Description
Size: Length 40-45 mm; Diameter of the column is 20-25 mm.

Color: Orange to gamboge in reticulate or mosaic bands around circumference. Tentacles with orange tips and yellowish tinge. Oral disc and actinopharynx red in color.

Column without cinclides, fully covered with verrucae. Circular muscles somewhat well developed. Mesogloea very thick. Ectoderm with numerous mucus cells. Endoderm not very thick. Limbus well pronounced. Tentacles upto 80 in number in large specimens; Long and pointed at the tip. Mesogloea relatively thick and ectoderm with mucus cells. They are with orange tips and with yelowish tinge. Inner and outer tentacles are almost of the same size. They are not fully retractile. Pedal disc broad and curves round to the substratum to grasp a ball of mud, gravel and shell particles present in the locality by which attachmet is effected. Oral disc large and flat. Radial muscles of the oral disc ectodermal. Tentacles arranged decamerously. Mouth large. Actinopharynx is longitudinally ridged and each of these ridges occures opposite to the insertion of the mesentery into the coelenteric wall. Sphincter weak endodermal and not circumscribed. 10 pairs of perfect Mesenteries, all fertile and filament bearing. The imperfect mesenteries (10 pairs) are present only at the proximal end of the body and devoid of filaments and gonads. The anemone always shows a decamerous arrangement of mesenteries and hence it may be regularly reproducing by sexual method only. Both marginal and oral stoma are present on all 10 pairs of perfect mesenteries. The anemone is primitive in having a lesser number of mesenteries and in the nature of the sphincter. But it shows advanced characters in having a well developed pedal disc, parietobasilar muscles and in the development of verrucae all over the column.
