Petroleum hydrocarbons, such as those released as a result of the Exxon Valdez spillage, have a greater effect on the feeding and growth of the mottled star than on one of its main prey species, the mussel Mytilus edulis.
A few of the species that contain his name are Troschel's sea star (Evasterias troschelii), Troschel's parrotfish (Chlorurus troschelii), Troschel's murex (Murex troschelii) and freshwater snail Bithynia troschelii.
