What is the larval form of the acanthocephalan called within the intermediate host?
Answer
Acanthellae
The indirect life cycle of the acanthocephalan involves several developmental stages across different hosts. After the egg is ingested by an appropriate intermediate host, typically an arthropod like a crustacean or insect, the egg hatches. The resulting larval form that develops within this intermediate host is specifically termed the acanthellae. Following this stage, the acanthellae further develops into the infective stage, which is the cystacanth, before the cycle continues upon ingestion by the definitive host.
