Pandalus
Encyclopedia
Pandalus is a genus
of shrimp
s in the family
Pandalidae
. Members of the genus are medium sized and live on or near the seabed. Some species are the subject of commercial fisheries and are caught by trawling. One species, Pandalus montagui
, lives in association with the reef-building polychaete
worm, Sabellaria spinulosa
.
The life span is typically 3–5 years with sexual maturity being reached at an early age. Members of this genus are protandric hermaphrodites, starting life as males and later becoming females. Reproduction takes place in the spring when up to 3,000 eggs are produced and fertilised internally. The female carries them around under the abdomen for about 6 days before they develop into planktotrophic larvae. These remain in the plankton
for 4–6 months. During this time they drift with the currents and have a dispersal potential of at least 10 kilometres (6.2 mi) The shrimps have a rapid growth rate and this means that populations can build up quite rapidly after disturbance or habitat destruction.

Shrimp
Shrimp are swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water. Adult shrimp are filter feeding benthic animals living close to the bottom. They can live in schools and can swim rapidly backwards. Shrimp are an important...

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Pandalidae
The family Pandalidae is a taxon of Caridean shrimp. These species are commonly called pandalid shrimps. They are edible and have high economic value. They are characterized by the subdivided carpus of the second pereiopod and, mainly, by the lack of the chelae of the first pereiopod...

Polychaete
The Polychaeta or polychaetes are a class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. Indeed, polychaetes are sometimes referred to as bristle worms. More than 10,000...
