Features of defense. Warning coloration is found in some of the brilliantly coloured shells and bodies of carnivorous marine snails that produce highly toxic poisons.An “extinct species” is a species of organism that can no longer be found in the wild or in captivity. A species is a classification of organisms which can reproduce successfully with one another.There are an estimated 60,000 – 80,000 species of gastropods, second only to the insects. They are typically called snails and slugs and are different in that they produce a single coiled shell. The shell is made of calcium carbonate (limestone) and is excreted from tissue called the mantle.Gastropods can mount distinct responses to different categories of pathogens, and can orchestrate effective elevated secondary responses under certain circumstances. Defense responses of at least one gastropod species, Biomphalaria glabrata, involve hemolymph lectins that are diversified by a variety of processes, including somatic diversification. Gastropod - Mollusks, Shells, Taxonomy: Given the antiquity of the gastropods, it is perhaps realistic to expect that most changes have occurred more than once.

The following new taxa are described (localities ...Gastropod - Reproduction, Life Cycles: The fertilized egg of gastropods hatches into a free-swimming form (trochophore larva). In some species, the swimming veliger stage persists for weeks or even months. Land gastropods exhibit internal fertilization. Egg production is correlated with the degree of care given to the eggs or young.Reviewed gastropods were recorded by species. Records of cryptic gastropods were presented by authors with variable levels of confidence but were …

Table 1 shows the list of bivalve and gastropod species found in mangrove forests of Cozo, Esteves, and Tinib in Casiguran, Aurora . A total of 22 taxa comprising eight species of bivalves and 14 species of gastropods were identified. The bivalves belong to five families with three families represented by a single species. Gastropods were more threatened (prop threat = 0.33; lower = 0.19, upper = 0.61) than bivalves (prop threat = 0.26; lower = 0.20, upper = 0.42; Table 1).Threat and data deficiency levels varied greatly amongst families (Table 2): for example, the bivalve family Unionidae had the most species in our sample (n = 190), with 33% estimated threatened …Gastropoda includes shell-bearing species as well as species with a reduced shell. These animals are asymmetrical and usually present a coiled shell. Shells may be planospiral (like a garden hose wound up), commonly seen in garden snails, or conispiral (like a spiral staircase), commonly seen in marine conches.
