Answer:
both are different in feeding behaviour and blowholes.
Step-by-step explanation:
The main difference between Mysteceti and odonticeti whales is the presence of feeding behaviour. Mysteceti whales also known as baleen whales which have baleen plates that capture prey from sea water while on the other hand, odonticeti whales have teeth which helps these whales to hunt aquatic animals. Baleen whales have baleen plates, or sheets, which sieve prey or food from seawater whereas toothed whales have teeth which helps them to actively hunt fish, squid and other sea creatures. The number of blowholes also different in both whales, Odontoceti whale has only 1 blowhole, but the Mysticeti has two blowholes in its body.
