 Known parasites include the tapeworms "Paraorygmatobothrium arnoldi", "Pseudogrillotia spratti", "Phoreiobothrium perilocrocodilus", and "Platybothrium jondoeorum".Sicklefin lemon sharks have been documented resting on the bottom and eliciting cleanings by bluestreak cleaner wrasses ("Labroides dimidiatus"), during which they may open their mouths and stop respiring for as long as 150 seconds to give the wrasses access to their mouths and gills.As with other members of its family, the sicklefin lemon shark is viviparous; the developing embryos are sustained by a placental connection formed from their depleted yolk sacs.
