Although snails infected by other Leucochloridium species are reported to continue to reproduce, [3] snails infected by L. paradoxum often show a reduction of the sexual organs. [ 6 ] The appearance and behaviour of the sporocysts is a case of aggressive mimicry , where the parasite vaguely resembles the food of the host, thereby gaining the ...
Leucochloridium is a genus of parasitic trematode worms in the order Diplostomida.It Is the sole genus in the family Leucochloridiidae. [2] Members of this genus cause pulsating swellings in the eye-stalks of snails (a phenomenon colloquially called a zombie snail), so as to attract the attention of predatory birds required in the parasites' lifecycle.
Furthermore, parasites take up glycogen and lipids from the hepatopancreas. [5] Cercariae: The cercariae measure 0.31 mm to 0.47 mm by 0.03 mm to 0.15 mm and live up to 48 hours in water. They have a tendency to infect snails that are at least 2.5 cm in length, though smaller snails have also been observed to shed cercariae. [12]
Over the next two to three months the larvae develop into adult male and female worms. The male remains small at 4 cm (1.6 in) long and 0.4 mm (0.016 in) wide; the female is comparatively large, often over 100 cm (39 in) long and 1.5 mm (0.059 in) wide. [5] Once the worms reach their adult size they mate, and the male dies. [6]

These larvae grow and take on a sac-like appearance. This stage is known as the sporocyst and it forms a central body in the snail's digestive gland that extends into a brood sac in the snail's head, muscular foot and eye-stalks. It is in the central body of the sporocyst where the parasite replicates itself, producing many tiny embryos .
Dillman said he was part of a team that made four trips to the Colorado River between March and August of 2023 to collect more than 2,000 snails of two distinct species known to transmit the worms.
