Purpura panama is the name of a snail from the family of spiny snails thatis commonin the Indo-Pacific .
features
The medium-sized, firm and spindle- to egg-shaped snail shell of Purpura panama , which reaches a length of about 6 cm in adult snails, has a large body circumference, a short thread and a large, egg-shaped housing mouth. The case is sculpted with spiral stripes, a row of low knots on the shoulder of the whorls of the thread and four rows on the whorl of the body. The spindle has a strong callus. The outer lip of the case mouth is thin and notched. The surface of the shell is brown with white lines and spots on the tubercles, the inside of the case mouth is cream-colored with fine red lines, yellow and brown on the edge, the spindle with brown spots.
Distribution, habitat and way of life
Purpura panama is distributed in the Indo-Pacific from the coasts of South Africa ( KwaZulu-Natal ) and East Africa to eastern Indonesia , north to Japan and south to southern Indonesia, where it can be found on rocky surfaces in the intertidal zone and a little below.
Life cycle
Like other new snails, Purpura panama is segregated. After mating, females come together to lay mat-shaped clutches with stalked egg capsules, from which Veliger larvae then hatch.
nutrition
Purpura panama eats mussels and barnacles , in whose shells it drills holes in order to get to the meat. Limpets , on the other hand, are captured by pulling them from the rock with her foot.
Importance to humans
Purpura panama is collected and marketed in India for its meat.
Status as Art
Purpura panama was described as Thais panama by Peter Friedrich Röding in 1798 . Since the species description of Purpura rudolphi by Jean-Baptiste de Lamarck in 1822, this species has repeatedly been synonymous with Purpura panama and even the common German name Rudolph's purple snail has been assigned to the latter. Purpura panama is still considered a separate species, but Purpura rudolphi is now a synonym for Purpura persica .
