A 395 kg shortfin mako, Isurus oxyrinchus (Lamnidae) landed at Montauk, New York in June of 1992 was found to contain two dead, but otherwise healthy appearing pugnose eels, Simenchelys parasiticus (Synaphobranchidae) within the lumen of its heart. The path along which the eels made their way into the shark's heart was not found. Histological examination of the shark's heart revealed the presence of medial hyperplasia and hypertrophy of small arterioles, multifocal arteriosclerosis, and… 
Functional Morphology of the Feeding Apparatus in Simenchelys parasitica (Simenchelyinae: Synaphobranchidae), an Alleged Parasitic Eel
TLDR
A comparison with other species provides several lines of evidence supporting the hypothesis that Pugnose Eels have a feeding apparatus that is equipped for biting off chunks of flesh from prey (irrespective of whether prey is dead or alive), most likely by using rotational feeding.
Distribution, abundance and biology of the smalltooth sandtiger shark Odontaspis ferox (Risso, 1810) (Lamniformes: Odontaspididae)
The smalltooth sandtiger shark, Odontaspis ferox, has a cosmopolitan distribution across warm temperate and tropical waters, and although essentially demersal, it has also been captured pelagically
Naturally occurring lesions and micro‐organisms in two species of free‐living sharks: the spiny dogfish, Squalus acanthias L., and the smooth dogfish, Mustelus canis (Mitchill), from the north‐western Atlantic
TLDR
The finding that apparently healthy sharks can harbour potentially debilitating lesions warrants the inclusion of histopathological studies in the management and conservation of sharks.
Ophichthids (Ophichthidae: Anguilliformes) within the body cavity of marine fishes: pseudoparasites?
Three snake eels (Ophichthidae) were found in three common pandoras (Pagellus erythrinus) from the north-western Mediterranean: two in the stomach and one embedded in the body cavity. This incidence

Evolution of alarm cues: a test of the kin selection hypothesis
TLDR
Investigation of whether individuals of the cichlid fish Pelvicachromis taeniatus respond differentially to alarm cues derived from kin and non-kin suggests that potential inclusive fitness benefits are not mediated by responses specific to individual alarm cues.
Evolution of alarm cues: a role for kin selection?
TLDR
Investigation of whether individuals of the cichlid fish Pelvicachromis taeniatus respond differentially to alarm cues derived from kin and non-kin suggests that potential inclusive fitness benefits are not mediated by responses specific to individual alarm cues.
