Hypnotists

Brood parasitism

Is where a parasite uses its host to raise its young - a little bit like the lazy Mayzie bird in Dr Suse's book, 'Horton hatches the egg', except, more sinister. Usually, trickery, mimicry and predation of the host's own eggs is involved.

Cuckoo catfish

While the cuckoo catfish doesn't use mimicry to trick the foster mother, a mouth-breeding cichlid fish, into picking up and adopting the catfish eggs, it is just as sinister as the cuckoo's chick who destroys the host's eggs. The catfish young hatches before the cichlid's and quickly gobbles up  its foster mother's own eggs. 

The parasitic fish exploit the hosts to avoid predation inside their hosts mouth.

Spider wasp

Body snatchers

  Parasitic plastic surgeons: Body snatchers Barnacle sacculina The barnacle parasitises its host, a crab, and attaches itself to the crab's body till death does them apart. This master plastic surgeon is what's called a body snatching parasite. See the parasite attached to the crab below:   Hans Hillewaert, 2005   The parasitic barnacle is similar to another body snatching parasite, a toungue-eating louse, Cymothoa exigua. The parasite attaches itself to the fish's mouth and becomes it's new tongue. Marco Vinci, 2013

Wild hitchhikers

  Wild hitchhikers Wild hitchhikers, is the name I have given to a group of organisms that hitchhike on other organisms to serve themselves. These group of organisms are called parasites. Technically speaking, parasites are helminths (flatworms), arthropods (insects), and protists. Broadly speaking, you can include pathogens (bacteria, viruses), and parasitoids (organisms that kill their hosts, e.g. wasps) as well. A major distinction between parasites and other disease causing agents is that Parasites don't usually kill their hosts, but do harm them in some ways (e.g. make them weaker compared to their counterparts). The natural world is swamped with these hitchhikers. Isn’t that scary! While it’s not exactly clear how many parasite species there are in total, some believe that upto 40% of all species could be parasitic. What is clear though that parasitic life style is adopted by creatures in over 15 phyla and over 4 of the 7 kingdoms of life. These include kingdoms plantae, anim
