#DidYouKnow there are more than 14,500 species of #copepods? Thats more copepods than #mammals (6k) or #birds (10k)! They are found in all habitats where water is found including oceans, lakes, caves, bromeliads, and even damp soil. They are also the most abundant animals in the ocean! 🦐🧪

Ectoparasitic copepods in the genus Salmincola Wilson, 1915 are considered harmful to host salmonids, yet experimental studies on the mechanism by which these copepods affect hosts are critically limited.
