6 letters animal with stric in the middle?

The animal you're looking for is "strick," which refers to a type of fish, but it seems you might be looking for a more common animal. The Word "lizard" fits the criteria of having six letters with "str" in the middle. However, "str" specifically in the middle of a six-letter animal name is quite rare. If you're open to a broader interpretation, "ostrich" could also work, though it has seven letters.
