Salamanders are a type of amphibians that is often overlooked. This suggests that acoustic crypsis is being used by whale mother-calf pairs to minimize the risk of eavesdropping and detection by predators while still allowing for communication between mother and calf over relatively short ranges. Despite high energetic demands from a large body, low mass-specific metabolic rates are likely powered by low heart rates. This Arctic creature has a long, tusk-like proboscis which is actually a tooth that grows continuously and can reach lengths of over 6 feet!
