BACKGROUND Natural products isolated from marine environments are well known for their pharmacodynamic potential in diverse disease treatments, such as for cancer or inflammatory conditions. Sea cucumbers are marine animals of the phylum Echinoderm and the class Holothuroidea, with leathery skin and gelatinous bodies. Sponges are important components of Persian Gulf animal communities, and the ...
Study of morphological, anatomical characteristics and metabolic assay some Ulva species (sea lettuce) in the coastal waters Persian Gulf, Iran
A total of 98 marine mammal records from Iranian coastal waters of the Persian Gulf and Gulf of Oman were compiled of which 66 are previously unpublished new records. Seventy-nine were from the Persian Gulf and 16 from the Gulf of Oman coast. The largest numbers of records were from Qeshm Island and Bushehr Provinces. Records of finless porpoise (Neophocaena phocaenoides), Indo-pacific humpba...
levels of the heavy metals copper (cu), zinc (zn), lead (pb), cadmium (cd), chromium (cr), nickel (ni), iron (fe) and manganese (mn) were determined by graphite furnace atomic absorption spectrophotometer (model 67og) in coastal water, sediments and soft tissues of the saccostrea cucullata, from the intertidal zone at five stations in the gulf of chabahar on the iranian coasts along the oman se...
Chlorophyll-a indicates the biomass of phytoplankton as the primary production. Chlorophyll-a changes indicate the situation of the ecosystem. The present study was conducted for monitoring it in the northern part of the Persian Gulf and Oman Gulf. For this purpose, CTD and NASA site information was used. Samplings were done from January-March 2018-2021. Mean southern waters chlorophyll-a in ...
A reproductive biology study of blue swimming crab, Portunus segnis (Forskal, 1775) in the northern Persian Gulf and Oman Sea, was conducted from May 2010 to October 2011. The results showed that the annual sex ratio is not M: F=1:1, with 51.9 % female. All the five stages of ovarian development of P. segnis were observed throughout the year. The size of ovigerous crabs varied from 103 to 155...

Iran has 1260 km of coastline that borders the Persian Gulf and the Oman Sea in the northwest Indian Ocean. Marine algae are one of the natural resources in the marine ecosystem which produce a wide range of new secondary metabolites with various biological activities that play an important role in the pharmaceutical care. In this study the cytotoxic activity of 28 marine algae of Chabahar coas...
The spatial distribution of benthic foraminiferal assemblage of Nayband Bay and Haleh Estuary in the North-West of the Persian Gulf, was explored during 2011-2012 . The relationship between spatial pattern of foraminifera assemblages and the ambient factors (i.e. water temperature, salinity, pH, dissolved oxygen, sediment grain size distribution, sediment organic content, and CaCO3 concentrati...
