If marriage is a special thing for the whole creatures, , maybe you should see how unique this fish wedding is.
iit's called as Angler Fish
and if you think the above picture is the male fish, you actually wrong, because the below picture was the male is.
the only thing makes them unique is when the male reaches his periphery he doesn't need to forage or other activities, the most thing he needs is only to find a suitable female and use tentacle teeth to bite the female body. then, the male keep continueing to cling to the female and eventually becomes a prominent creature on the female body.
so, if you're part the male angler fish fish, just say good bye for it, because you could never seen him anymore.
