Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual References: Norman, C. P., Jones, M. B. 1993. Reproductive ecology of the velvet swimming crab, Necora puber (Brachyura: Portunidae), at Plymouth. Journal of the Marine Biological Association of the United Kingdom, 73(2), pp. 379-389. Comments: In spring and summer velvet crabs will reproduce in similar but shorter life cycle as that of the edible crab. Velvet crabs lifespan is around 5 years and are understood to reach maturity at 1 year. |

Marine ecology progress series. Oldendorf, 119(1), pp. 139-154. Comments: Invertebrates such as crustaceans and molluscs and also carrion or even brown algae. More likely to be predatorial at greater depths. |

Habitat modifying ability potential (?) | Unknown Comments: Not available. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Cubbon, K., Capper, A., Irving, A. D., Li, Y., Bell, M., Taggart, M. A. Metal Accumulation in Commercially Important Velvet Crab (Necora Puber) in the Orkney Islands, Scotland. |
Known human health impact? | Known Comments: Harmless. |
Known economic impact? | Known References: Shelmerdine, R. L., White, E. 2011. Escape gaps for velvet crabs (Necora puber): stock and economic benefits for the catching sector. Comments: The crab Necora puber is a decapod crustacean of great commercial interest. On the coasts of Galicia (NW Spain) this species has clearly been over-exploited. |
Known measurable environmental impact? | Not known Comments: Not available. |
