Louisea edeaensis

The crayfish or crab

It was first described by Bott in 1969.

Decapods are ten-legged crustaceans — crabs, shrimps, and crayfishes. Freshwater species here are usually tied to a drainage.

Malacostracans include crayfishes, crabs, and shrimps. Freshwater species are often narrow endemics.

Range and habitat

Louisea edeaensis is recorded from Cameroon and Iceland.

GBIF currently lists 10 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Habits

Freshwater crayfishes and crabs walk the bed. Dams, silt, and introduced species cut a drainage into fragments they cannot cross.

Crayfishes and crabs need cover and clean water. A named form from one creek is not interchangeable with the next drainage.

In crisis

Louisea edeaensis is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
