3/3/2024 0 Comments Puffer fish drawings![]() So let me know what is your favorite fish, or do you know any names of any fish? You can let me know in the Q and A, and you can do that by using the Q and A button at the bottom of your screen, the one with the double speech bubbles.Īll right. So my favorite fish is the grouper, because I think they are super friendly and fun, and I also think they're really cute. So some of you might already know that I love the deep ocean, and my favorite deep ocean habitat is a hydrothermal vent, and to get us started thinking about the deep ocean today, I'm really curious to talk about fish with all of you. So before we begin, I want to give a special thanks to our generous donors, volunteers, and other important partners who enable us to discover, create, and share new knowledge with the world today and every day free of charge. And I'm going to go over a couple of details to allow everyone to get time to grab those materials. I have mine right here, and a pencil or a pen. So for today's activity, you are going to need a piece of paper. And for our new explorers, we are so happy that you have joined us today. So far we have doodled the deep sea, made jellyfish puppets, and today we are drawing fish with some really cool ocean experts. So as I said before, my name is Lara, and I am a museum educator at the National Museum of Natural History in Washington, D.C., and welcome back to those of you who were here yesterday or earlier this week. My name is Lara, and I am going to be talking with you today and the rest of this week about deep sea adaptations, so welcome. Thank you so much for joining us, everybody. “The beautiful lines and structure could serve only to channel those particles to the center, and have no aesthetic purpose,” one of the researchers told LiveScience.Webinar: Deep Sea Animal Adaptations Week – Deep Sea Fishes and Sketching There is a chance that it’s only the fine sand the females are after, not the formations’ intricate patterns or symmetry. If things go well, however, the female will lay her eggs in the center of the circle, and then, like most fishes, the males will fertilize those eggs externally. Third, the male gathers fine sediments to give the resulting formation a distinctive look and coloring, Kawase said.įemales base their decision about whether or not to mate with a male upon his construction skills, although the researchers still don’t understand what it is, exactly, that females are looking for in their ideal circular pattern, LiveScience says. Second, the male decorates these ridges with fragments of shells. It takes about seven to nine days for the pufferfish to construct the circles.Īlthough some other fishes construct mating mounds, the pufferfish’s creation is unique for a number of reasons:įirst, they involve radially aligned ridges and valleys outside the nest site. Although the fish are only about 12 centimeters (5 inches) long, the formations they make measure about 2 meters (7 feet) in diameter. Males laboriously flap their fins as they swim along the seafloor, resulting in disrupted sediment and amazing circular patterns. Males, LiveScience explains, create the structures to attract females. Now, the mystery has been solved: pufferfish are the culprits. The team of researchers behind the finding declared that the “huge geometrical structures” play a role in this species’ mating rituals. ![]() But since 1995, when they were first discovered in Japan, no one could explain these phenomena. In certain tracts of ocean, divers know to look for “underwater crop circles,” ornate symmetrical patterns temporarily carved into the sandy sea floor.
