Invertebrates are animals that do not have a backbone. Invertebrates, which make up the vast majority of known animal species, have, in recent years, attracted much research attention to the possibility that environmental chemicals capable of perturbing the endocrine functions of vertebrates can also disrupt endocrine signaling or endocrine-like signaling processes in invertebrates. Ocean invertebrates range from microscopic zooplankton to the massive giant squid (which can reach almost 60 feet in length! Lined shore crabs do require access to water to moisten their gills and feed. This is the ability to detect noxious stimuli which evokes a reflex response that moves the entire animal, or the affected part of its body, away from the source of the stimulus. 300.
