The second known species in the genus Colletteichthys is described from the Arabian Peninsula and the northern ArabianSea, supporting the validity of the genus Colletteichthys. Compared to the other known species, C. dussumieri from India,C. occidentalis has only a single tentacle above the eye whereas C. dussumieri has two or more. Colletteichtyhs dussumieri is restricted to the west coast of India.

The presently reported study identified Saurida lessepsianus Russell, Golani et Tikochinski, 2015 from the west coast of India, which was earlier diagnosed as Saurida undosquamis (Richardson, 1848) due to their morphological similarities. Saurida lessepsianus is characterized by 48–51 lateral line scales, 44–47 vertebrae, 3–6 rows of teeth on tongue and anterior part of stomach black. The identity of this species was also confirmed by molecular examination (phylogenetic analysis of the COI sequences) and the study revealed a genetic divergence value of 0.08 between S. lessepsianus and S. undosquamis. Our study confirms the extended distribution of S. lessepsianus along the west coast of India (eastern Arabian Sea) from the Red Sea-Mediterranean Sea.

ECMWF (Europian Centre for Medium Range Weather Forecasting )  predicted 72 hr flow pattern at 850 hPa has been used to develop a quantitative method for value addition in the district level dynamical forecast system for intense rainfall over the west coast. It has been found that the amount of rainfall over the west coast is significantly correlated to 72 hr ECMWF forecast of maximum wind speed over the Arabian Sea along the west coast. The latitudinal width of the heavy rainfall belt over the west coast has got significant correlation with the location of maximum wind core along the west coast. It has been  shown that the strength and location of the 72 hr predicted core and fetch of maximum winds could be used as potential predictors in the value addition for 72 hr heavy rainfall forecast along the west coast of India during summer monsoon.

Importance of sea surface temperature (SST) over the Arabian Sea, Bay of Bengal and the north Indian Ocean is studied in relation with the formation and m1intenan';e of the southwest monsoon over India. SST over southeast Arabian Sea close to the west coast of India becomes maximum before the onset of monsoon over Kerala. Crossing of the equator by southern hemispheric warm water seems to be related with the early or late onset of the monsoon. Magnitude of the difference between SST and air temperature during pre-onset weeks gives valuable hints for early/late and excess/deficient monsoon. A large warm winter mass up to the depth of 100 metres shifts towards the west coast of India before the onset of the monsoon. In 1979, back and forth movement of this water mass seems to be related with the different phases of the monsoon over India.
