thermophilic; lower temperatures interfere and delay development and completion of the life cycle. The eggs are released into the water through the fish fecal material, where they hatch into free-swimming hexacanth (six-hooked) larvae. Between 1 and 28 days, the eggs will hatch according to the water temperature range it is in. Eggs that hatch within 1–5 days occur at temperatures between 28 and 30 °C and eggs that hatch within 10–28 days occur at temperatures between 14 and 15 °C.

The discovery of the tapeworm's substantial infections within the crucian carp population in the UK is of particular concern because there have not been any known natural tapeworm parasites of these crucian carp. A plausible cause may be that the crucian carp have limited immunological defenses against this parasite. In Australia, introduced

The parasite attaches near the anterior portion of the intestine, just posterior to the bile duct. An accumulation of tapeworms in this area leads to digestive tract blockage that distends the intestinal wall leading to perforation. When attached,
