Strepsirrhines are a suborder of primates that include animals like lemurs, lorises, and galagos. They are primarily found in Madagascar and parts of Africa and Asia. Strepsirrhines are known for their wet noses, which help them detect scents better than other primates. They also have large eyes and a keen sense of smell, making them well-adapted to their environments. These primates are generally smaller than their relatives, the haplorhines, which include monkeys and apes. Strepsirrhines are often nocturnal, meaning they are active at night. Their social structures can vary, with some species living in groups while others are more solitary.
