Life of Sea | Mantis Shrimp | Mantis shrimp is marine crustaceans, the members of the order Stomatopoda. Although
often animals and are among the most important predators in many
shallow, tropical and sub-tropical marine habitats they are poorly
understood as many species spend most of their lives hidden in caves and
holes. They have name "Mantis" shrimp because they seem to look and hunt characteristics of a praying mantis insect. Approximately 400 species of mantis shrimp are currently described in the world, all living species in the suborder Unipeltata.
Mantis shrimp is an aggressive and typically solitary sea creatures spend most of their
time hiding in rock formations or burrowing intricate passageways in the
seabed. Or they wait for prey to chance upon them or, unlike most crustaceans, actually hunt, hunt and kill prey. They rarely leave their homes except to feed and move, and can be daytime, nighttime or dim, depending on the species. Most
species live in tropical and subtropical seas (Indian and Pacific
Oceans between eastern Africa and Hawaii), although some live in
There are two categories hunt of Mantis shrimp, the "spearers" and "smashers". The "spearers" use their spear-like claw to silently stabbing soft tissued prey. The "Smashers" use their powerful, club-like claw touching, bursting open or pulverize harder bodied prey. It
is interesting that the power of the "smashers". Appendix may produce a
hit near the power of a .22 caliber bullet and are notoriously known as
"thumb splitters". Rumor has it that due to the enormous power of these animals, they can crack aquarium glass. Smashers
use this ability to snails, crabs, molluscs and rock oysters to attack,
their blunt clubs so that the shells of their prey to crack into
pieces. Spearers other hand, the preferred meat of softer animals, like fish, with barbs and hooks claws easier cutting.
Mantis shrimp have a long lifespan and exhibit complex behavior, such as ritualized fighting. Some
species use fluorescent patterns on their bodies for signaling with
their own and maybe even other species, expanding their range of
behavioral signals. They can learn and remember well, and are able to recognize individual neighbors with whom they regularly interact. They can recognize them by visual signs and even by individual smell. Many have developed complex social behavior to defend their space against rivals. In life, they can as much as 20 or 30 breeding episodes. Depending
on the species, the eggs are laid and kept in a cave, or they can be
worn under the tail of the female until they hatch. In monogamous species, the Mantis shrimp remain with the same partner for 20 years. They share the same burrow and may be able to coordinate their activities. Both sexes often care for the eggs.
eyes of Mantis shrimps can be for different types of coral, prey (which
are often transparent or semi-transparent), or predators such as
barracuda, shimmering scales that can be recognized. Alternatively, the manner in which mantis shrimp hunt (very rapid movements of the claws) a very

fact that those with the most advanced vision also are the species with
the most colorful bodies, suggests that the evolution of color vision
has taken the same direction as the tail of the peacock.

and now sometimes referred to as "thumb splitters" because the ability
of animals to painful cuts to inflict if handled carelessly. Mantis shrimp has powerful claws that they use to attack and kill their prey by spearing, stunning or dismemberment. Although
it happens rarely, some larger species of Mantis shrimps are able to
break through aquarium glass with a strike from this weapon. Many saltwater aquarium to keep stomatopods in captivity. These aquarists may play a role in understanding the mysteries of the mantis shrimp. However,
mantis shrimps considered pests by other aquarium hobbyists, because
many types of percussion make burrows in the exoskeletons of dead
corals. It is not uncommon for a piece of coral skeleton, also known as live rock, live mantis shrimp into an aquarium. Once in the tank, they feed on fish, corals and tiny crustaceans.
