Mer info så alla förstår hur farliga de är även för oss människor the beautiful sea apples (e.g., Pseudocolochirus violaceus and P. tricolor) also lack these Cuverian tubules, but along with Bohadachia argus and Actinopyga agassizii, are considered among the most toxic sea cucumbers in the world. In fact, according to Wilkens (1998), it takes only about 1g of tissue from any of these particularly toxic species to poison the fish in a 25g tank. These toxins also affect humans, and many people suffer moderate to severe skin and eye irritation if they come into contact with these toxins (Cunningham and Goetz 1996). Some cases in which toxins came into direct contact with the eyes have resulted in blindness, and deaths have even been reported in cases where people have eaten these animals without the proper preparation.
