Parasites

By John Fearnhead.

What is a parasite?

• A parasite is a creature living in or on another creature and drawing its food directly from it.

• The parasite that I am about to show you are all invertebrates.

Cymothoa exigua

• Cymothoa exigua, otherwise known as the tongue eating louse.

• Cymothoa exigua eat fishes tongues and takes the tongues place.

• When the fish eats the parasite takes some of the fishes food.

Hookworms

• Hookworms eat things in their host’s gut [Humans can be hosts too].

• Doctors use hookworms to cure some diseases such as colitis.

• This means doctors could give you hookworms to eat!

Botfly

• A botfly lays its eggs in the skin of the cow.• The egg hatches into a larva which eats its

host to grow.• When the botfly is fully grown it eats its way

out.

Conclusion

• I have shown you some parasites but there are many more.

• There is a parasite for every animal.ss
