What a Nut!— Invasive Species Week

This ctenophore (a stingless jellyfish-like animal) called a sea walnut is native to the east coast of North and South America. In 1982, it was discovered in the Black Sea, where it was transported by ballast water. It subsequently spread to the Caspian Sea. In both places, it multiplied and formed immense populations. The sea walnuts contributed to the collapse of local fisheries because they feed on zooplankton that the commercial fish also consume. Mnemiopsis leidy has also been discovered in the Mediterranean, Baltic, and North Seas.

Phytoplankton blooms produce some fascinating textures in Earth’s oceans, and consequently we’ve shared images of them taken from orbit many times (http://tinyurl.com/qhzwbr9, http://tinyurl.com/pwasxol). This bloom, however is a bit different from the others – in this photo from NASA’s Aqua satellite, it looks, well, black.

This may look like a beautiful flower blooming beneath the waves, but it’s actually an animal! 

This stalked crinoid was spotted in the deep waters of National Marine Sanctuary of American Samoa. The feathery “petals” you see are arms, which this invertebrate uses to grasp small particles of food out of the current. Crinoids can also use these arms to crawl along the seafloor if they need to relocate!

Dinoflagellates The dinoflagellates are a large group of flagellate protists. Most are marine plankton, but they are common in fresh water habitats as well. They are characterized by two flagella, one girdling the cell and the other trailing the cell. Some dinoflagellates exist in coral, in a symbiotic relationship. These dinoflagellates are termed the zooxanthellae. Other dinoflagellates occur in such high numbers that the water is colored red, a phenomenon known as a red tide.

#4—Fun Facts for World Whale Day

Whales are the biggest creatures to ever live on the earth. The largest whale, the blue whale, can be over 90 feet long. The sperm whale, on the other hand, may not be the biggest whale, but it has the biggest brain to have ever existed on Earth.

Shark Week Takeover with photos by @BrianSkerry ! • • • Like a living wreath, small fish encircle the head of a whale shark cruising through coastal waters off Mexico’s Isla Holbox. The small fish have little to fear from this shark, since whale sharks are filter feeders, eating mainly plankton and fish eggs. Whale sharks are currently listed as ‘vulnerable’ due to human pollution and hunting, and populations remain unstable due to the slow reproductive habits of these magnificent creatures.

Swimming with whale sharks is one of my favorite experiences in the sea. Their massive size and gentle nature make for exhilarating encounters. • • • To see more shark photos and other ocean wildlife follow @BrianSkerry And keep following our feed all week to keep up with Brian Skerry’s very sharky takeover! #takeover #sharks #sharkweek #sharkweek2018 #allsharksallthetime #newenglandaquarium
