Pinniped High levels of organic chemicals accumulate in these animals since they are near the top of food chains and have large reserves of blubber. Lactating mothers can pass the toxins on to their young. These pollutants can cause gastrointestinal cancers, decreased reproductivity and greater vulnerability to infectious diseases. Other man-made threats include habitat destruction by oil and gas exploitation, encroachment by boats, and underwater noise. Pinniped Pinnipeds, commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared
Jugulator (mammal) displayed these behaviours. "Jugulator" occurs in the mid-Cretaceous deposits of the Cedar Mountain Formation, where several of North America's more iconic dinosaurs like "Utahraptor" and "Cedarosaurus" occur. A large variety of mammal species are known from here as well, including other eutriconodonts like "Astroconodon" and "Corviconodon" as well as multituberculates like "Cedaromys" and "Janumys" and several therian mammals such as "Montanalestes" and "Atokatheridium". These diverse mammal faunas offer a transition from dominant taxa in the Early Cretaceous and the multituberculate and therian dominated laurasian mammalian faunas of the Late Cretaceous. Jugulator (mammal) Jugulator is a genus of extinct mammal from
