Relating to parasites that live on the outside of their host's body.
Fleas and ticks are examples of ectoparasitic organisms that can harm pets.
Ectoparasitic → It is formed from "ecto-" (from Greek "ektos", meaning outside) and "parasitus" (from Latin, meaning one who eats at another's table, or parasite). The word describes organisms that live on the outside of a host and derive nourishment from it.
Think of 'ecto-' meaning 'outside' and 'parasite' as something that feeds off another. This helps you remember that 'ectoparasitic' refers to organisms that live on the outside of their host.
