Abstract: The present paper deals with a study of eleven species of
Peridinium
from inshore waters of Karachi. All the species are first reports from
Pakistan’s coastal area.
Peridinium truncatum is recorded from the Indian Ocean for the first time. The
species diversity of
Peridinium
was very high from October to December, 1970, which is the post-monsoon
period in the N. Arabian Sea. Most species indicated the coastal nature
of the area under study. The temperature and salinity ranges within
which all the species were found growing in nature are given.
