I don't usually think about how big or small an animal is when I am given just the measurements. It's often when I see the animal next to something I can recognize, that it really sinks in.
If you can't tell in the picture, that is a Giant Manta Ray with a scuba diver placing a satellite tracking tag on it.
My nephew asked me to draw him some Valentine cards to give to his class. Of course he asked me this a couple of days before his school was celebrating Valentines day, so I told him they probably wouldn't be ready on time. And they wouldn't be. But he did inspire these first drafts! Happy St. Valentines Day!
