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.
ecological relationships of flukes
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.
Blood flukes infect humans, but they use water snails as an intermediate host. Their life cycle is as follows: 1. eggs released in water hatch 2. larvae infect water snails 3. in snail larvae develop into a different stage larvae which are again released in the water 4. these larvae can penetrate the skin of human hosts 5. in humans the blood flukes mature and settle in veins around the gut or bladder 6. mature blood flukes produce new eggs which are released in water 7. goto 1.
Some are e.g. liver flukes, but others are not e.g. a whale's fluke.
