Remarks: The shape of the hook-like or spine-like process shows some variation in different genera, but it is undoubtedly homologous throughout the whole series. The function of this organ is unknown.

Distribution of P. indica in the Indian Ocean (upper water column of 200 m).
Triangle: South West Moonsoon season: April 16 to October 15 (white triangle = negative stations; black = animals collected). Circle: North East Moonsoon season: October 16 to April 15 (white circle = negative stations; black = numbers of ianimals collected).
Nota: High densities were recorded in the area north of 10°N the Gulf of Oman and in the central Bay of Bengal. Towards the south it extends to 10°S in moderate numbers and further south the number decreases considerably and the species is completely absent south of 30°S except along the South African coast. Maximum number in a standard haul was obtained from a night station during the NE monsoon season, located near the mouth of the Gulf of Oman. |

Distribution of P. indica (Number per haul based on standard collections (mosthy 200-0 m) in the indian Ocean.
Nota: Zooplankton collections taken from The Indian Ocean during the International Indian Ocean (IIOE 1962-1965).
For the authors P. indicashowed a positive correlation with salinity and phosphate and a negative relationship with dissolved oxygen. Measurement of specimens from different areas showed that individuals from the locality whjch had the maximum density of the species were slightly smaller in size when compared to those from other areas. The females ranged from 1.6 to 2.8 mm, the smallest being in the area of the Gulf of Oman. Males ranged from 1.5 to 2.1 mm.
The position of the pigment spot was found to vary in males in relation to the position of geniculate antennule. When the geniculate A1 was on the right side, pigment spot was found on the left and vice versa. In females also the spot was either on the left or on the right side.
It appears that P. indica which is the only one in the genus which can survive in a nutrient rich environment of high salinity and low oxygen, had taken advantage of the upwelling, to produce dense populations of the species in the northern areas of the Arabian Sea. |

Vertical abundance of females, males and late copepodites.
Nota: The numbers of this species were the highest for the genus Pleuromamma during the Krill Expedition in the Pacific east tropical (23°N to 3°S). The species was found at most of the stations. Females occurred primarily between 250 and 600 m during the day. The depths of maximum concentrations were from 350 to 400 m between 6°N and 8°N. Maximum numbers were 2800 individuals/1000 3.
Female vertical distribution at night was from 150 to 300 m between 20°N and 3°N. It appears that vertical distribution was shallower north of 12°PN than south of this latitude. The data suggest that the species undergoes diel vertical migration.
The mean percentage combined was 1.8% (day: 0.6, night: 3.0) for all samples with the bongo net .

The mean female size is 2.219 mm (n = 14; SD = 0.3730), and the mean male size is 1,968 mm (n = 10; SD = 0.3002). The size ratio (male : female) is 0.84 (n = 5; SD = 0.0122). | | | | Rem.: | Timonin (1971, p.282) considers the trophic interrelations in the equatorial and tropical Indian Ocean, and divides the plankters into 6 trophic groups from the litterature and the results of studies of mouth-parts structure and intestine content. This species is omnivorous.
