๐ฌ Catfish cancer spreading in Lake Memphremagog
Strange black tumors, identified as melanomas, have affected roughly one-third of brown bullhead catfish in Lake Memphremagog, spanning Vermont and Quebec. Genetic evidence suggests this cancer might be spreading from one catfish to another, potentially marking the first documented transmissible cancer in a fish species. Researchers hypothesize transmission could occur during spawning season when fish aggregate closely. However, some scientists believe environmental toxins like arsenic might be the primary cause of the lesions. The scientific community is currently debating whether this is a contagious clone or an environmental issue. ๐ฌ
