Final answer:
Shared characteristics among diverse animals from corals to monkeys include the presence of specialized tissues. These specialized tissues are part of a group known as Eumetazoa, which encompasses most animal species.
Step-by-step explanation:
Among animals ranging from corals to monkeys, a characteristic that is shared is the presence of specialized tissues. All animals, except for sponges (Parazoa), have specialized tissues, which is a hallmark of a group known as Eumetazoa. From simple organisms like corals, which may have nerve and muscle tissues, to complex organisms such as monkeys, which have a wide array of specialized tissues, this feature is common across the animal kingdom.
Other features such as having a mouth and an anus, sexual reproduction, and a fixed number of embryonic tissue layers are also common among many animals but are not universal, as there are exceptions. For instance, not all animals have a mouth and anus (some have a combined opening called a cloaca), and not all animals reproduce sexually (some have asexual reproduction modes).
