Definition
Proper noun * Hylobatidae: A taxonomic family within the order Primates, comprising the lesser apes, which include gibbons and siamangs. In some biological classifications, this family is considered a subfamily (Hylobatinae) of the family Pongidae.
Usage Notes
- The term Hylobatidae is used primarily in scientific and zoological contexts for formal classification.
- It specifically refers to a distinct family of primates, separating the smaller, arboreal "lesser apes" (gibbons and siamangs) from the "great apes" (such as orangutans, gorillas, and chimpanzees).
Examples
- The agile brachiators of the family Hylobatidae are found in the tropical rainforests of Southeast Asia.
- A key anatomical feature distinguishing Hylobatidae from other apes is the presence of ischial callosities.
- The study focused on the vocal communication systems within Hylobatidae.
Advanced Usage
- Phylogenetic context: In modern cladistics, Hylobatidae is recognized as the sister group to the family Hominidae (which includes great apes and humans), forming the superfamily Hominoidea.
- Conservation status: Many species within Hylobatidae are listed as endangered due to habitat loss and fragmentation.
