Some of our most visited resources are overview pages. These are vetted by experts in the field and dive deep into a subject, ecosystem, or animal group. #SmithsonianEdu
Our most recently published overview covers all things whales

We’ll continue to share our overviews on this thread so you can explore from home - as a part of lesson plans or independent learning. #SmithsonianEdu
Our #GiantSquid page explores the massive (it can reach lengths of over 40 feet!) and elusive invertebrate

Interested in jellyfish & comb jellies? Everything about these gelatinous creatures on our overview page is vetted by @collins_noaasi @InvertebratesDC. https://ocean.si.edu/ocean-life/invertebrates/jellyfish-and-comb-jellies
We’ve got info on all #sharks, from the smallest (the dwarf lantern shark) to the largest (the whale shark) on our shark overview

One-quarter of all ocean species depend on #CoralReefs so, of course, we have a page focused on this vital ecosystem! https://ocean.si.edu/ocean-life/invertebrates/corals-and-coral-reefs
Sea turtles require air to breathe and land to lay their eggs. However, the majority of their lives are spent underwater. Learn more about the seven living species! https://ocean.si.edu/ocean-life/reptiles/sea-turtles
Penguins can be a bit awkward on land, but they swim swiftly and elegantly underwater. The emperor penguin is the fastest, reaching 9 mph (14 km/hr) when in a hurry

Need some help understanding #OceanAcidification? We cover the cause, chemistry, and impacts in this overview. #SmithsonianEdu https://ocean.si.edu/ocean-life/invertebrates/ocean-acidification
#MarinePlastics, pieces both big and small, are an ongoing ocean conservation issue. There are #OceanOptimism solutions though, and we discuss those as well in our overview. https://ocean.si.edu/conservation/pollution/marine-plastics
#ClimateChange drives #SeaLevelRise. This overview covers the complexities like why some areas of the ocean will see more or less and the reasons behind the rise. https://ocean.si.edu/through-time/ancient-seas/sea-level-rise
The #GulfOilSpill occurred 10 years ago this month. We look at the impacts on the ecosystem, and research that has happened since in this overview. https://ocean.si.edu/conservation/pollution/gulf-oil-spill
With their roots submerged in water, mangrove trees thrive in hot, muddy, salty conditions that would quickly kill most plants. More about how they survive in this overview. https://ocean.si.edu/ocean-life/plants-algae/mangroves
Hurricane season officially starts June 1 in the Atlantic. Unfortunately, when it arrives, storms won’t provide us a break and can wreak further havoc on an already stressed system. https://ocean.si.edu/planet-ocean/waves-storms-tsunamis/hurricanes-typhoons-and-cyclones
Marine microbes are a group that includes bacteria, viruses, archaea, protists, and fungi. If you weighed all the living organisms in the ocean, 90 percent of that weight would be from #microbes. https://ocean.si.edu/ocean-life/microbes/marine-microbes

We really learned a lot putting together an overview of the ocean through time—from the first oceans of the Hadean to the present day, we cover it all. #SmithsonianEdu https://ocean.si.edu/through-time/ocean-through-time
