Douglas Harper's Etymology Dictionary
remora

1560s, from Latin remora "sucking fish," literally "delay, hindrance," from re- "back" (see re-) + mora "delay" (see moratorium); so called because the fish were believed by the ancients to retard a vessel to which they attached themselves. Hence, in 17c.-18c., "an obstacle, an impediment" (the first sense of the word in Johnson's dictionary). In Greek, ekheneis, from ekhein "to hold" + naus (dative nei) "ship." Pliny writes that Antony's galley was delayed by one at Actium. Sometimes called in English stayship or stopship.

Wikipedia
Remora

The remoras (pronounced or ), sometimes called suckerfish, are a family (Echeneidae) of ray-finned fish in the order Perciformes. They grow to long, and their distinctive first dorsal fins take the form of a modified oval, sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals. By sliding backward, the remora can increase the suction, or it can release itself by swimming forward. Remoras sometimes attach to small boats. They swim well on their own, with a sinuous, or curved, motion.
