Inshore. Neritic.
For Mulyadi (2002, p.37)this species resembles C. minorand C. americana.
After Lacuna & al. (2013, p.77) the P5 of both sexes showed absence of setules on the inner and outer margins, however these attibutes were seen on the same organism from the Indian waters. Further, difference can also be observed between results from Mindanao and those in Indonesian waters. For instance, in Indonesian waters 18 segments for yje female A1 were observed, but our study described only 17, female swimming leg 5 reported as 3-segmented in Indonesian waters, however in Mindanao waters 4-segmented only. These variations exhibited between the same species from different places may be interpreted as an evidence of some kind of genetic switch mechanism. | | | Last update : 03/12/2020 | |
