Answer: Crabeater Seal Teeth 

The Crabeater seal is found along the Antarctic coastline and is the most populous species of seal. Their scientific name is Lobodon carcinophaga, which means “lobed-tooth crab lover”, despite not feeding on crabs. In a previous “What on Earth”, we discussed a special adaptation that allows some whales to filter their food using hair-like structures that hang from the roof of their mouth.  

The main gaps fit between each other, allowing them to filter krill out of mouthfuls of water, which pass though the gaps in the tubercles. This food source makes up around 95% of their diet and they also feed on fish and cephalopods.
