Anglerfish. Fun fact about Angler fish: The bigger ones you see in movies and photos are the females. The males are much smaller and are born pretty damned helpless. The males blunder around in the dark until they find a female and then they bite her. Like grrrrr... until they are firmly attached. The female then forms skin around the male and end up sharing a vasculature. So when the female is ready to release eggs, she sends a hormone to her little male appendage and he releases sperm. Ahhh... deep-sea love <3
Shown on a 16 ounce Kleen Kanteen. Last photo for display only. This listing is for a single sticker.
It measures 2.75" (70mm) across by 2" (51mm) tall. Made from thick, durable vinyl that is waterproof, UV protected, can last outdoors up to 5 years with a permanent adhesive. I have had a one of these on my car for about 7 years and can attest to its durability.  It also does just fine on a water bottle through the dishwasher.
