Snails can be found in a very wide range of environments, including ditches, deserts, and the abyssal depths of the sea. Although land snails may be more familiar to laymen, marine snails constitute the majority of snail species, and have much greater diversity and a greater biomass. After the a priori species identification, one or more specimens of each species, for a total of 285 (130 gastropods and 155 crabs) specimens, were selected for molecular analyses.

If there are a lot of crown conches in the area, and other species that typically live there are missing, it’s an indication of poor water quality. This can, in turn, affect the oyster and clam populations. Gas­tropods are by far the largest group of mol­luscs. Their 40,000 species com­prise over 80% of liv­ing mol­luscs. Gas­tro­pod feed­ing habits are ex­tremely var­ied, al­though most species make use of a radula in some as­pect of their feed­ing be­hav­ior. Nonetheless, within a mangrove forest, variations in temperature, humidity, water, and salinity can affect the distribution of different species associated with mangroves (crabs, gastropods, worms (e.g., Sasekumar, 1974)) according to their physiological requirements (Alongi, 2008; Shi et al., 2016).Multiple studies have shown that Phasmarhabditis’ efficacy as a biological control agent is dependent on the size or life stage of the gastropod host.
