Ever seen a fish attached to a shark or a manta ray while they’re swimming about?
Well, these are Remoras. They have an organ on top of their head which allows them to attach to larger fish like sharks and rays to hitch rides and feed of its parasites and waste. Pretty cool adaption.
Aspidonia, plate 47 from Kunstformen der Natur (1904), by Ernst Haekel
* Haekel has combined Horseshoe Crabs, Trilobites and Euryptids (Sea Scorpions) in one group, “Aspidonia” which no modern scientists recognize, though both groups are considered to be Arthropods.
