(CNN) Pesto the baby penguin is already taller than his parents. Now he’s a social media star. Quoting,

Penguins are also sexually dimorphic, which means you can’t tell their sex by looking at them. In order to discover the genders of their penguins, keepers take a small drop of blood from the penguin’s toe and send it to a lab in order to get an official answer.

WRONG. The correct meaning is exactly the opposite. Quoting Wikipedia,

Sexual dimorphism is the condition where sexes of the same species exhibit different morphological characteristics, including characteristics not directly involved in reproduction.[1] The condition occurs in most dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits.

A correct statement:  Penguins are not sexually dimorphic.
