fulica has been considered the most important snail pest in the tropics and subtropics and perhaps the world.
fulica is also a vector of Angiostrongylus cantonensis (Nematoda; Protostrongylidae), the roundworm responsible for eosinophilic meningo-encephalitis in humans and the spread of the disease has been correlated with the spread of A.
fulica are extremely dangerous from the perspective of the conservation of native snail species.
Mascarene CootFulica newtoni is known from numerous travelers' reports and bones from Réunion (to France), and also probably occurred on Mauritius from where there were reports of poule d'eau, the contemporary name used for the birds on Réunion.
Birds were last reported on Réunion (by Dubois) in 1672, and on Mauritius (by Leguat) in 1693, and were presumably hunted to extinction despite the fact that they were “not good to eat”.
In the 20th century the rate of introduction rose to four species per decade; with the exception of the 1950s when the rate was even higher due to the intentional introduction of biocontrol agents for a pestiferous snail species Achatina fulica.
fulica and found the largest prey size to be 49 mm in length, while the average size of prey was 10-30 mm in length, mainly juveniles.
fulica has decreased in numbers as a result of both predation and the introduction of disases (Gerlach 2001).
While the heparins isolated from various mollusks are structurally different from human heparin (6) and pharmaceutical heparins(7, 8), mollusk heparins contain antithrombin-dependent anticoagulant activity associated with the presence of the unique 3-O-sulfated glucosamine residue found in the antithrombin pentasaccharide binding site common to all anticoagulant heparins(5, 8, 9, 10, 11).
fulica is a very large gastropod that requires substantial quantities of calcium for its shell(37, 47).
fulica is known to make a bactericidal glycoprotein that is found in its mucus(50), suggesting that snail GAG may have a protective role.
Many Florida residents remember the problem with Achatina fulica when it was introduced in this state.
Achatina fulica has no natural predator in Brasil and the shell competes with some local species, especially with the Megalobulimus group.
Miracatu is on the border of our most important Atlantic tropical rain forest park, where it is possible to find over 25 different described species of Megalobulimidae and Strophocheilidae and many other new species.
RESPONSE OF AMERICAN COOTS AND SORAS TO HERBICIDE-INDUCED VEGETATION CHANGES IN WETLANDS(Site not responding. Last check: 2007-10-18)

American Coots (Fulica americana) and Soras (Porzana carolina) are species that are seldom considered when wetland habitat management plans are implemented to benefit waterfowl (Alisauskas and Arnold 1994, Eddieman et al.
The effects of herbicide-induced changes in wetland vegetation (largely cattails, Typha spp.) on densities of American Coots (Fulica americana) and Soras (Porzana carolina) were assessed in northeastern North Dakota.
However, the coots it parasitises are the three lowland ones, White-winged (Fulica leucoptera), Red-gartered (Fulica armillata) and Red-fronted (Fulica rufifrons) coots.
The rare and local Horned Coot (Fulica cornuta) is only found in a few high Andean lakes of Argentina, Bolivia and Chile, not Paraguay which has no Andean highlands.
There is an old paper on the Horned Coot that I haven't read for a while, maybe its time to refresh my memory on what it said.

Snails come in a range of different sizes.
The largest land snail is the Giant African Snail (Achatina fulica;Family (additional info and facts about Achatinidae) Achatinidae), which can measure up to 30 cm.
Pomacea maculata (Family (additional info and facts about Ampullariidae) Ampullariidae), or Giant (additional info and facts about Apple Snail) Apple Snail is the largest freshwater snail, with its size reaching 15 cm diameter and over 600 g (An artifact that is heavy) weight.
American Coots (Fulica americana) wintering on the Savannah River Site (SRS), near Aiken, South Carolina, arrive in stages and exhibit temporally stable patterns of site fidelity.
Site fidelity in colormarked coots was observed both throughout the winter and across years (Pottei- 1987) on various portions of Par Pond reservoir on the SRS.
