The animals which don’t' have separate sexes are called as:

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about animals that do not have separate sexes. This means we are looking for a term that describes organisms that possess both male and female reproductive organs.

2. **Identifying Key Terms**: The key terms in the question are "separate sexes" and "animals." We need to focus on the classification of animals based on their reproductive structures.

3. **Defining Sexual Dimorphism**: Sexual dimorphism refers to the differences in appearance between male and female members of the same species. In animals with separate sexes, these differences can be pronounced.

4. **Recognizing Hermaphroditism**: In contrast to sexually dimorphic animals, some animals are hermaphrodites. This means that a single organism has both male and female reproductive parts, allowing it to perform both reproductive roles.

5. **Examples of Hermaphroditic Animals**: Common examples of hermaphroditic animals include certain groups such as Annelida (segmented worms) and Platyhelminthes (flatworms). These organisms do not have distinct male or female forms.

6. **Conclusion**: Therefore, the animals which don’t have separate sexes are called hermaphrodites.

**Final Answer**: Hermaphrodites.
