When an animal is gravid it means that they are pregnant or carrying eggs. This term is often used in conjunction with amphibians and reptiles.
Some animals that are referred to in this definition are: lizards, turtles, snakes, frogs, and toads.
With nearly 5 decades of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge. I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or in the air. I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!
