Developmental trait (?) | Brooding References: Fincham AA (1977) Larval development of British prawns and shrimps (Crustacea: Decapoda: Natantia). Laboratory methods and a review of Palaemon (Paleander) elegans Rathke 1837. Bulletin of the British Museum (Natural History) (Zoology), 32:1-28 Comments: The species breeds from April to September, in favourable conditions females may produce two broods per year. As in all palaemonids, the eggs are protected by females and remain attached to her pleopods until the planctonic larva hatches. Then it undergoes typical development with variable number of zoeal stages recorded (from six to nine). The larva changes lifestyle to benthic in megalope (post-larval) stage. |
Characteristic feeding method / Life stage (?) |
Comments: P. elegans is omnivorous, feeding predominantly on algae, small crustaceans and foraminiferans. |
Mobility / Life stage (?) |
|
Salinity tolerance range (?) | Exact range: 5 - 25 References: Palaemon elegans (rock shrimp) CABI Invasive Species compendium http://www.cabi.org/isc/datasheet/70617 Comments: 1 - 40 tolerated |
Habitat modifying ability potential (?) | Keystone species Comments: P. elegans is known to outcompete and replace native palaemonid shrimps (P. adspersus and Palaemonetes varians) from inshore, lagoon and estuarine habitats. |
Toxicity / Life stage (?) | Not relevant References: White SL, Rainbow PS (1986) Accumulation of cadmium by Palaemon elegans (Crustacea: Decapoda). Marine Ecology Progress Series, 32:17-25 Comments: The species is known to accumulate cadmium in its tissues. |
