What is a shrimp, and what are my shrimp?

The number of people who think shrimp are fish is tragic, so let’s clear up a few things!

Shrimp are invertebrates, lacking a backbone. It is ‘important’ to recognise that not all animals commonly called shrimp are actually shrimp. The well-known mantis shrimp, for example, is a stomatopod rather than a decapod. They’re also terrifying.

Taxonomic classification:

Kingdom – Animalia:            Shrimp are animals.
Phylum – Arthropoda:        Shrimp are arthropods.
Subphylum – Crustacea:        Shrimp are crustaceans.
Class – Malacostraca:     Shrimp are malacostracans.
Order – Decapoda:         Shrimp are decapods.
Suborder – Pleocyemata:      Shrimp are pleocyematans(?).
Infraorder – Caridea:             Shrimp are carideans.

I focus on the shrimp with the following further taxonomic groups.

Family – Atyidae
Genus – Caridina, (Others include Paracaridina, Neocaridina, Halocaridina)

Etymology:

‘Caridina’ is apparently derived from Greek for ‘small shrimp’ or ‘small crustacean’. Thanks to Werner Klotz for this information.

‘Para-‘ is a Greek root for ‘near’. Paracaridina – near ‘Caridina’.
‘Neo-‘ is a Greek root for ‘new’. Neocaridina – new ‘Caridina’.
‘Halo-‘ is a Greek root for ‘salt’. Halocaridina – salt ‘Caridina’. [These species have salt tolerance.]
