Squirt here to talk about how temperature changes in the water column. The surface waters (epipelagic layer) tend to be warmer than deeper waters because they are warmed by sunlight. The bathypelagic layer feels very cold to me. I live happily in the mesopelagic layer because the waters are just right. Other factors that affect water temperature are longitudinal location and water currents. Waters closer to the poles are colder than waters which are close to the equator. Have you ever seen pictures of the Southern Ocean? There are usually chunks of ice floating. Brrr... I don't think I like the cold waters at the poles! Do you like the cold?
Hi everyone! Squirt here to talk about cephalopods. Cephalopods are a group of marine animals that includes cuttlefishes, nautiluses, octopods, and squids - like myself! There are over 900 known species of cephalopods. Cephalopods are invertebrates, this means they do not have a backbone. Some consider cephalopods the most intelligent marine invertebrates because they have big brains. Some cephalopods are bioluminescent while others can change colors like a chameleon when they feel threatened or want to blend in to their surroundings! One of the most noticeable features of cephalopods are their dangling arms. These arms help cephalopods capture prey and navigate through the water. Check out the arms on the cephalopods below. Octopus have 8 arms and squids have 8 arms and 2 tentacles….. Pretty cool tools to have when capturing food!
Squirt here! Did you know that light is made up of a rainbow of wavelengths? Marsh Myers tells us all about what happens to light in the ocean in the video I want to share with you today. He also shares with us how some animals camouflage in the dark waters. Ask an adult if you can make your own animal using construction paper. I'd love to see pictures of the animal you create in the comments section! Check out the video here: https://www.youtube.com/watch?v=4ZyWUjedm7s
Hi everyone! Today I want to share a video about water pressure with you. Water pressure is the pressure exerted on an item due to the weight of water above it. The degree of water pressure increases as you dive deeper because more water is above you. This video shows you how water pressure affects different items. Ask an adult to help you try out the egg experiment Marsh Myers talks about. Please share your results in the comment section, I'm excited to see what you found. Just follow this link for the video: https://www.youtube.com/watch?v=yTQ_7_DFGyQ
Good morning Kids! Are you ready for our next matching game?
This time we will dive into the depths of the bathypelagic layer. The bathypelagic zone extends from 4000 - 6000 meters. Waters in this layer is completely dark as no sunlight penetrates this deep. With the help of a light I caught a: giant isopod, threadfin dragonfish, phanthom anglerfish, google-eye, bathynermest, humpback anglerfish, squid, tripod fish, and slender snipe eel. Can you guess who's who in the image below? The answers can be found under the image.
A. Google-eye; B. Tripod fish; C. Giant isopod; D. Squid; E. Humpback anglerfish; F. Threadfin dragonfish; G. Slender snipe eel; H. Bathynemertest; and I. Phanthom anglerfish. Photographs by Dante B. Fenolio.
