The howler monkeys of the genus Alouatta are among the largest and most widespread of new world monkeys and are famed for their loud vocalizations, among the loudest of all terrestrial animals. With the aid of an enlarged hyoid bone the guttural howls of these monkeys can be heard up to 3 miles (4.8 km) away.

Primates TOOB (Safari Ltd.)

Review of the 2019 Primates TOOB by Safari Ltd. I had bought this set early on when I started my Synoptic Collection, mainly for the marmoset and tamarins. I have since retained the bonobo and sifaka too, pending eventual release of standard-sized figures of these species. This TOOB is another example of Safari Ltd recently upping the game in their TOOB sets, with others being Whales (2018), Dolphins (2019), Great Lakes (2020), African Savannah (2020), and Pelagic Fishes (2019).
