Krill - Wikipedia, the free encyclopedia (3462 words)
There are also some ectoparasites of the family Dajidae that afflict krill (and also shrimps and mysids); one such parasite is Oculophryxus bicaulis which has been found on the krill Stylocheiron affine and S.
It attaches itself to the eyestalk of the animal and sucks blood from its head; it is believed that it inhibits the reproduction of its host as none of the afflicted animals found reached maturity.

Euphausiids of Southeast Asian waters (843 words)
Only Stylocheiron species, which do not migrate vertically, extend much beyond the edge of the shelf, rarely entering the Gulf of Thailand.
This suggests that the speciation process (population isolations + re-invasions) in Stylocheiron, a genus consisting of members which do not migrate vertically, each occupying a discrete depth interval, may differ from that process in strongly migrating genera such as Euphausia and Thysanopoda.
The importance of the Indo-Australian region in the evolution of sub-tropical and tropical species is indicated by 1) the large number of species found there, 2) the present partitioning of central water mass species distributions (e.g.
