baleen whale
C2Technical / Scientific
Definition
Meaning
A large whale that has baleen plates instead of teeth for filtering small food from seawater.
Any whale belonging to the parvorder Mysticeti, characterized by a comb-like baleen apparatus for filter feeding on krill, plankton, and small fish. These whales often have two blowholes.
Linguistics
Semantic Notes
The term is a compound noun. 'Baleen' refers to the keratinous material forming the plates. The term is a hypernym for specific species (e.g., blue whale, humpback whale). Often contrasted with 'toothed whale' (Odontoceti).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'китовый ус кит'. The standard Russian term is 'усатый кит'.
- Do not confuse with 'синий кит' (blue whale), which is a type of baleen whale.
Common Mistakes
- Pronouncing 'baleen' to rhyme with 'balloon' (it is /bəˌliːn/).
- Using 'baleen' as a countable noun for the whale itself (e.g., 'We saw a baleen' is wrong; it's 'a baleen whale').

FAQ
Frequently Asked Questions
No. Dolphins are toothed whales (Odontoceti), not baleen whales (Mysticeti).
Baleen is made of keratin, the same protein found in human hair and fingernails.
The blue whale is the largest baleen whale and the largest animal ever known to have existed.
Generally, no. Echolocation is a trait associated with toothed whales. Baleen whales primarily use low-frequency sounds for communication over long distances.
