of the Red Sea and some fishes were purchased from
Al-Mehwat fish market at Al-Hodeidah city, Yemen.
Fishes were freshly brought to the laboratory and their
whole body surface, inside the mouth and the gill
arches were examined for parasites. Table 1 gives a
list of these fishes with their families, numbers and
both their range and mean length. Fish scientific
names were checked according to Froese and Pauly
(2013). Parasites were removed from their hosts and
preserved in 10% seawater formalin. Parasites appendages
were dissected out with a needle in pure phenol for the
study of temporary mounts. The drawings were made
by using a camera Lucida and photographs were made
with a Samsung digital camera, 10.1 mega pixels.
