Etymology: Genus name of Mochokus
is the latinisation of Mouchchouéké,
Arabic name for M. niloticus, roughly translating
as “don’t get stung or jabbed by it,”
referring to its dangerously sharp spines, which local
fishermen try to avoid. Specific name of niloticus
–icus, belonging to the Nile River near Thebes,
Egypt, the type locality. Remarks:
This species has a wide distribution, with no known
major widespread threats. It is therefore listed as
Least Concern. It has also been assessed regionally
as Least Concern for eastern, north eastern and western
Africa. In north Africa, the species is assessed as
Vulnerable (IUCN 2020).
