What a species-specific relationship is?

Answer 1

Question = what a species-specific relationship is?

Answer = Read the following para carefully you will get your answer =

"""Most species of whale lice are associated with a specific species of whale.

They remain with their host throughout their entire development and do not go through a free-swimming phase.

Although the relationship between a specific species of whale louse and a specific species of whale is more pronounced with baleen whales than with toothed whales,

almost every species of whale has a specific species of louse that is unique to it.

With the sperm whale the parasitic relationship is in addition s*x-specific.

The whale louse Cyamus catodontis lives exclusively on the skin of the male sperm whale, while Neocyamus physeteris is found only on females and the young."""" ( end )

When two differnt species are associated with each other ( Be it mutualism ; parasitism as in the case above or ; commensalism) AND the association is such that a particular species is associated with another but very definite and constant species the it is ' Species - specific relationship.
