It is a symbiotic relatiionship, a parasitic relationship, meaning it benefits the parasite but harms the host.

flukes inhabit the elk veins and feed off of them, causing harm
A parasitic relationship. The fluke (if it is a blood fluke) takes needed nutrients from the elk's blood, which can harm the elk.
Flukes have a parasitic ecological relationship with their hosts, often living in the digestive, circulatory, or respiratory system of animals. They can cause harm to their hosts and impact their health and fitness. Flukes may also serve as intermediate hosts for other parasites, completing their life cycle and spreading infection.
What are blood flukes?
Flukes are bigger than flounders, plus the flukes eyes migrate to the left side of their head and the flounder to the right side of their head.

There are many types of flukes for different animals. In humans, we can be infected with a couple of types of liver flukes, a lung fluke, and blood flukes.
monogenea are ectoparasitic while trematoda are endoparasitic
The elk and wildebeast have distinct physical differences, but elk live in North America and wildebeast live in Africa.
There are 1,099 miles between Cheyenne and Elk Grove.
Flukes are a type of tapeworm that is parasitic. They have suctioned mouths and are generally not segmented. Most are only a few centimeters long.
Some are e.g. liver flukes, but others are not e.g. a whale's fluke.
