### Taxonomy and Classification
Bothriocephalus is classified within the family Bothriocephalidae. The genus includes several species, many of which are known to parasitize fish hosts, impacting both wild and cultured populations.
### Morphology
Members of the genus Bothriocephalus exhibit the typical tapeworm body plan, consisting of a scolex (head) equipped with bothria—elongated, slit-like suckers used for attachment to the host’s intestinal wall. Their bodies are segmented into proglottids, which contain reproductive organs.
### Life Cycle
The life cycle of Bothriocephalus species involves multiple hosts. Eggs released into the water hatch into free-swimming larvae, which infect intermediate hosts such as small crustaceans. Fish become infected by consuming these intermediate hosts, where the larvae develop into adult tapeworms.
### Ecological and Economic Importance
Bothriocephalus species can cause parasitic infections in fish, sometimes leading to reduced growth and health. This has implications for fisheries and aquaculture, where infestations may affect productivity.
**Meta Description**
Bothriocephalus is a genus of tapeworms that parasitize freshwater and marine fish. These flatworms have complex life cycles involving multiple hosts and can impact fish health and aquaculture.
