Question

Based on the relationship, fill the given blank.
Whale: Baleen plates; _ _ _ _ _: Bat

Answer 1

Hint: The baleen plates are webbed plates that are arranged horizontally used for filter feeding. In addition, the same bats use modified limbs to do the same function.

Complete answer: The whales are aquatic animals and baleen plates are a filter-feeding system present inside the mouth of baleen whales. Instead of teeth baleen whales have baleen. Baleen acts as a filter. Once the whale is underwater it opens its mouth and pushes out the water and animals as small fishes remain inside as a source of food. Like that as in whales, bats have wings or patagium, which is a membranous structure used for climbing and handling food. The wings of bats are of a webbed type and are different from those of other birds. This type of structure is present in an extinct group of animals and birds.

So, the correct answer for the above relationship is wings or patagium.

Additional information: Baleen is used for making baskets, backscratchers, collar stiffeners, switches, and crinoline petticoats. Baleen was commonly used as a creased paper because of its flexibility. Baleen is also referred to as whalebone. The use of the whalebone is now replaced with synthetic materials like plastic and fiberglass.

Note: The patagium like structure is present in extinct groups of animals which also includes the dinosaur Psittacosaurus in which it extended from its ankle to its tail. Scientists are carrying out research to find out whether early baleen whales had teeth or not.
