Evolution of parasitic life in the ocean

In addition, after the infection of a new host group, parasites might encounter certain problems that prevent fu ...

However, which characteristics facilitate the evolutionary transitions from nonparasitic to a parasitic lifestyle are unclear. I will attempt to answer this question by studying a tractable social parasitic system. Social ...

Parasitoid
A parasitoid is an organism that spends a significant portion of its life history attached to or within a single host organism in a relationship that is in essence parasitic; unlike a true parasite, however, it ultimately sterilises or kills, and sometimes consumes, the host. Thus parasitoids are similar to typical parasites except in the more dire prognosis for the host.
