Life History/Behavioral Trends, cont. - Primates are gregarious. We live in groups and are very social. II. Primates: Strepsirhinis- The primate Order is divided into two suborders: Strepsirhini and Haplorhini.- Characteristics of Strepsirhinis:- Rhinarium (wet nose)- Attached upper lip- Tapetum lucidum (reflective retinas)- Different blood supply to uterus- Postorbital Structure (the bony bar that all primates have to protect the eyes)- Metopic Suture (The forehead is separated into two halves connected by a suture.)- Unfused Symphysis (Their jaw is separated into two halves connected by a suture.)- Toothcomb- Grooming clawThese notes represent a detailed interpretation of the professor’s lecture.
