Stomatopods

چکیده
What is a stomatopod? Stomatopod crustaceans are commonly known as mantis shrimp, because their preycatching (raptorial) appendages resemble those of praying mantises. They are strictly marine and are quite distinctive from all other crustaceans, having separated from them roughly 400 million years ago and having evolved on their own unique track ever since. About 500 species are recognized today, most living in shallow tropical waters on sand flats or in coral reefs. While unfamiliar to most people, mantis shrimps are actually very common in these habitats.

Intraspecific deception by bluffing: a defense strategy of newly molted stomatopods (arthropoda: crustacea).
After molting, stomatopods can be evicted easily from home cavities by conspecifics because these marine crustaceans lose temporarily their body armor and the use of their raptorial appendages. Some newly molted stomatopods defend their cavities with a meral spread display, a signal correlated with attack when used by animals between molts. The use of the meral spread display actually increases...
متن کاملThe evolutionary history of Stomatopoda (Crustacea: Malacostraca) inferred from molecular data
The crustacean order Stomatopoda comprises seven superfamilies of mantis shrimps, found in coastal waters of the tropics and subtropics. These marine carnivores bear notable raptorial appendages for smashing or spearing prey. We investigated the evolutionary relationships among stomatopods using phylogenetic analyses of three mitochondrial and two nuclear markers. Our analyses recovered the sup...
متن کاملEye design and color signaling in a stomatopod crustacean Gonodactylus smithii.
Many species of stomatopod crustaceans have multiple spectral classes of photoreceptors in their retinas. Behavioral evidence also indicates that stomatopods are capable of discriminating objects by their spectral differences alone. Most animals use only two to four different types of photoreceptors in their color vision systems, typically with broad sensitivity functions, but the stomatopods a...
متن کاملPublished in Marine and Freshwater Behaviour and Physiology2009 42(4):219-232 Adaptive signalling behaviour in stomatopods under varying light conditions
Stomatopod crustaceans (mantis shrimp) are aggressive benthic marine predators with extraordinary color vision. When communicating with conspecifics, many stomatopods display conspicuously colored body areas, often in combination with other types of signals such as motion and chemical cues. Some species occupy wide depth ranges (>30 m), where changing light conditions can influence color percep...
متن کاملMultimodal signals: ultraviolet reflectance and chemical cues in stomatopod agonistic encounters
Complex signals are commonly used during intraspecific contests over resources to assess an opponent's fighting ability and/or aggressive state. Stomatopod crustaceans may use complex signals when competing aggressively for refuges. Before physical attacks, stomatopods assess their opponents using chemical cues and perform threat displays showing a coloured patch, the meral spot. In some specie...
متن کاملFrom odor molecules to plume tracking: an interdisciplinary, multilevel approach to olfaction in stomatopods.
Like many marine crustaceans, mantis shrimp rely on their sense of smell to find food, mates, and habitat. In order for olfaction to function, odorant molecules in the surrounding fluid must gain access to the animal's chemosensors. Thus fluid motion is important for olfaction, both in terms of the large scale fluid movements (currents, waves, etc.) that advect the odorants to the vicinity of t...
