Sub-species level (?) | Not entered |
Native origin (?) | Ocean: Atlantic --> Ocean region: NW Atlantic References (not structured): Alonso, G., Tablado, A., Gappa J. L., Magaldi, N. 1995. Seasonal changes in an intertidal population of the amphipod Ampithoe valida (Smith, 1873). Oebalia, 21, pp. 77-91. |
Life form / Life stage (?) |
References (not structured): Hiebert, T.C. 2015. Ampithoe valida. In: Oregon Estuarine Invertebrates: Rudys' Illustrated Guide to Common Species, 3rd ed. T.C. Hiebert, B.A. Butler and A.L. Shanks (eds.). University of Oregon Libraries and Oregon Institute of Marine Biology, Charleston, OR. Comments: A tube-dweller that rarely leaves the tube, A. valida can swim rapidly for short periods if needed. |
Sociability / Life stage (?) |
|
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual References: Borowsky, B. 1983. Reproductive behavior of three tube-building peracarid crustaceans: Jassa falcata, Ampithoe valida, and the taniad Tanais cavolinii. Marine Biology, 77(3), pp. 257-263. Comments: Ampithoe valida is known to reproduce sexually. In amphipods, reproduction involves the male transferring spermatophores to the female, which then fertilize the eggs. The fertilized eggs are brooded by the female in a specialized ventral pouch called a marsupium until they hatch into juvenile amphipods. |
Developmental trait (?) | Brooding References: Borowsky, B. 1983. Reproductive behavior of three tube-building peracarid crustaceans: Jassa falcata, Ampithoe valida, and the taniad Tanais cavolinii. Marine Biology, 77(3), pp. 257-263. Comments: This reproductive strategy, which includes brooding, provides a protective environment for the developing embryos, increasing their chances of survival. The species typically exhibits high reproductive rates, producing multiple broods over the course of a breeding season. |
Characteristic feeding method / Life stage (?) |

Physiological responses of Ampithoe valida and its feeding potential on Ulva prolifera. Marine Environmental Research, 186, 105942. Pardal, M. A., Marques, J. C., Metelo, I., Lillebø, A. I., Flindt, M. R. 2000. Impact of eutrophication on the life cycle, population dynamics and production of Ampithoe valida (Amphipoda) along an estuarine spatial gradient (Mondego estuary, Portugal). Marine Ecology Progress Series, 196, pp. 207-219. Comments: Ampithoe are omnivorous, with a feeding preference for macroalgae such as U. prolifera, but also on some organic detritus. Grazing studies have shown that A. lacertosa grazes macroalgae (e.g. Ulva spp.) faster than eelgrasses, while the opposite is true for the grazing habits of the congener, A. valida, that consumes eelgrasses more readily than it does macroalgae. |
Mobility / Life stage (?) |
References (not structured): Hiebert, T.C. 2015. Ampithoe valida. In: Oregon Estuarine Invertebrates: Rudys' Illustrated Guide to Common Species, 3rd ed. T.C. Hiebert, B.A. Butler and A.L. Shanks (eds.). University of Oregon Libraries and Oregon Institute of Marine Biology, Charleston, OR. Comments: A. valida typically moves slowly along the substrate, such as seagrass beds and algae. Also capable of swimming. Although it primarily resides in the benthic zone, it can swim through the water column using its appendages. This ability allows it to move between different parts of its habitat, escape predators, and disperse. |
Salinity tolerance range (?) | Exact range: 10 - 40 References: Li, C., Tang, Y., Sun, W., Xia, J., Xia, Z., Zhang, J., He, P., Liu, J., Zhao, S. 2023. Physiological responses of Ampithoe valida and its feeding potential on Ulva prolifera. Marine Environmental Research, 186, 105942. Comments: Ampithoe valida could survive under temperatures of 5–30 °C, salinities of 5–40, and pH of 4–10, with suitable growth in the ranges of 15–25 °C, 10–40 psu, and 6–10, respectively. |

Known measurable environmental impact? | Known References: Li, C., Tang, Y., Sun, W., Xia, J., Xia, Z., Zhang, J., He, P., Liu, J., Zhao, S. 2023. Physiological responses of Ampithoe valida and its feeding potential on Ulva prolifera. Marine Environmental Research, 186, 105942. Comments: A. valida showed well growth and could effectively reduce U. prolifera biomass. |
