Bearded seals spend most of their lives in the Arctic waters, although they’ve been seen in southeast Florida! They enjoy feasting on arctic cod, shrimp, clams, crabs, and octopus and have been known to live up to 25 years. Learn more here.
This past Friday I had a particularly curious and enthusiastic fifth block Oceanography class. All of their questions were marine science related so I broke out some notecards and asked them to write all of their burning inquiries down. I wanted to tackle them thoughtfully … here I am! My students are amazing inspiration and I’m quite grateful to them for some fun reason to get back to writing here.
My most entertaining question was “What’s the most extravagant animal in the ocean?” I mean, there are just so many ways to think on it. I asked on Twitter and got lots of good ideas … Since I spend my days in a high school, I went with some superlative options. These are a few I came up with but I am looking to see what you all might think: Octopus (Most likely to win a Noble Prize in Physics), Frogfish (Most confident), Erect-crested penguin (Coolest hair), Leafy sea dragon (Best dressed), or the Whale shark (Biggest life of the party).
Please send some other suggestions!
Maybe it’s because I’m a full-time teacher now, but my favorite character in Finding Dory is the Sting Ray. I mean, if it wasn’t for the class trip to learn about migration Dory – the blue tang with short-term memory loss – may never had thought about “going home” and the trek to look for her parents may never have happened. She is supported on the journey with Marlin and Nemo – a class act father and son clown anemonefish duo. However, they meet some other amazing new creatures and reconnect with some old friends. Here are some of my favorite facts to share about Hank the Octopus, Destiny the Whale Shark, Bailey the Beluga, Crush the Green Sea Turtle, and – of course, the Sting Ray Teacher!
What are your thoughts on the Finding Dory film? Did anyone catch that Dory should now have been able to speak “whale” because of her friendship with Destiny – given Destiny is actually a fish and not a whale?
I won’t say it has anything to do with us … oh, wait … yes, I will. The ocean is getting warmer because of climate change. One effect of this would be that many animals that pretty much only preferred the luxurious tropical waters of the south Atlantic now find the Mid-Atlantic waters great! Oh, fun. Except in the case of the man-of-war this summer. That’s got a lot of folks sketched out and seems to be putting a damper on beach days. Well, at least there’s the opportunity to learn something new … because that’s what summer’s all about, right? Here is a list of fifteen surprising facts about the man-of-war (Number twelve is shockingly cool!):
- The man-of-war is not a jellyfish. They’re a siphonophore, a single animal made of a colonial of organisms working together (e.g., coral colony).
- The man-of-war is made up of four polyps. The top one is a brilliantly purple, blue, or pink gas-filled float. When the top polyp (i.e., “sail”) is filled with gas it looks like the 18th century Portuguese war ship at full mast.
- The top polyp is like an umbrella for the others polyps that are bunched under it. One is made up tentacles full of stinging cells (i.e., nematocysts). They’re used to catch prey such as smaller fish, plankton, and crustaceans.
- The tentacles with the stinging cells can get to be 165 feet (that’s longer than a blue whale!) long, but are more on average about 50 feet.
- Man-of-war are asexual. That’s right … not a man or a woman! One polyp is responsible for all that action. If you’re counting, that’s three of the four polyps. Can you guess what the fourth is responsible for? Digestion.
- The gas that the man-of-war is filled with is Argon. That’s number 18 on the atomic table.
- The man-of-war (or, man-o-war) is also sometimes called the bluebottle.
- People have died from trying to swim into shore after getting stung by them. However, the sting itself will most likely not kill a human.
- Man-of-war that have washed up to shore can still sting you. I was stung by one in Florida. While it was incredibly painful at the time, I lived to tell about it. Here is a “How Not to Get Stung” list.
- Man-of-war tend to travel together (up to 1000!) and drift in the wind or current (Note: They do not swim and therefore do not migrate). However, they’ll deflate if there is a threat at the surface of the sea.
- The eight centimeter fish Nomeus gronovii is immune to the man-of-war’s stinging cells and lives among its tentacles.
- The blanket octopus is also immune to them and not only eats them but also reuses the tentacles to help in hunting other animals. Check out a video of that action here.
- The fossil records for the man-of-war go back 600 million years.
- South Florida-based fine art photographer Aaron Ansarov was featured in National Geographic for his beautiful images of the man-of-war. Check them out … I am still speechless!
- There is a Man-O-War Cay in the Abaco Islands of the Bahamas. I’ve been to nearby Guana Cay several times, so I am quite grateful that over at Rolling Harbour the beautiful place has been described just as I remember.
Psst … Can someone help me out with the plural of man-of-war? Is it men-of-war or man-of-wars?
Are we one step closer to an invisibility cloak?
Researchers at the University of Bristol have demonstrated how to create artificial skin that can mimic the squid. The squid, as well as other cephalopods like the octopus and cuttlefish, can blend into their surroundings to hide from predators or sneak up on prey. The squid’s “Passing Cloud” camouflage technique (i.e., bands of color spread as waves across the skin) was simulated in the experiment. According to the researchers the implications are more than just avoiding your landlord, they noted that “It could also be used for signaling purposes, for example search and rescue operations when people who are in danger need to stand out”. More patterns are being studied in the future as well.
On Feb. 13, 1997, about 20 miles off the coast of England, a massive wave hit the freighter Tokio Express, toppling 62 giant containers into the rough north Atlantic seas.
Trapped inside one of them: nearly 5 million Legos. Many floated to the surface. Carried by currents, they’re still being found on beaches around the world nearly two decades later. Others remain on the ocean floor. It’s not unusual for fishermen trawling the Atlantic to haul up tiny Legos.
The fact that so many of the pieces were nautical themed – sea dragons, pirate swords, sea grass and scuba gear, among others – has turned the Lego spill into one of the most famous and unusual marine debris incidents in recent maritime history.
In Newquay, a seaside town in England, writer and longtime beachcomber Tracey Williams started a Facebook page a few years ago – Legos Lost at Sea – that tracks the whereabouts of the lost Legos as they wash up onto beaches.
Williams recently spoke to the Beach Chair Scientist blog about her work, and you can hear more of what she has to say below. But she hopes to turn the public fascination, much of it generated from a recent BBC story on the spill, into a teaching moment about the harmful environmental impact of marine debris.
“Clearly, 5 million pieces of Legos spilling into the ocean isn’t good for the environment,” Williams said in a recent phone interview. After the BBC interviewed her about her site a while back, the publicity resulted in people contacting her with stories about beach-bound Legos around the world.
“It has connected beachcombers all around the world, which is fascinating,” Williams said.
She received one report of a Lego flipper found on an Australian beach. She’s also heard from the family of a woman who had scoured the beaches for Lego dragons as a hobby in her 80s, passing her finds along t0 younger generations.
“Obviously, marine debris is a big problem. But I think many children have been captivated by this whole Lego story … I think it reminds people of their childhood. It’s the whole issue of marine debris. Oceanographers are interested in how far it’s spread.”
Meanwhile, she also hears from fishermen who come across Lego pieces in their nets.
“Half of it sinks and half of it floats,” Williams said, referring to the sorts of Legos that fell off the Tokio Express. “So clearly, while we’re finding certain items washed up on our shores like the spear guns and the flippers, fishermen are actually finding other pieces like window frames and car chassis.”
While the lost Legos have made for fun beach combing and treasure hunts, there are bigger questions beneath the surface. If the contents of just one toppled shipping container can spread around the world for decades, what about far bigger and more dangerous spills that go unnoticed because they don’t happen to have Legos in them?
“There were 62 containers that fell off the Tokio Express back in 1997 and we only know about what was in three of them,” Williams said.
“What’s in all of the others and when will that all wash ashore?”

The rather short snout with thick, long, white whiskers gives this true seal it’s appropriate common name. The bearded seal (Erignathus barbatus) can be as long 8 feet and weigh up to 800 pounds. I guess now we know what idiom they use under the sea instead of “the 800 pound gorilla in the room …”. These seals tend not to be seen in packs like their more social counterparts we view along harbors.
Bearded seals spend most of their lives in the Arctic waters, although one was recently found in southeast Florida. They enjoy feasting on arctic cod, shrimp, clams, crabs, and octopus and have been known to live up to 25 years. For more information on the conservation efforts and status of the bearded seal population please check out this page created by the NOAA Fisheries Service Office of Protected Resources.

We took our daughter to her first major league baseball game this weekend. I will never forget her cheery face when she’d point at the bright orange and black cartoon Orioles on fan’s shirts and say, “buuurrd?” The Phillies lost so it wasn’t the best experience we could have hoped for at Camden Yards, but overall my little family had an enjoyable time (also, impressive despite the 90 degree weather).
Needless to say, the day got me thinking about marine-themed mascots for major league sports in the U.S. This is a list of 9 marine mascots that might inspire your little marine biologists to follow baseball, hockey, or football or conversely that could get your little sports fan into science. I suppose if you’re a teacher, these mascots are also useful teaching tools to introduce different biological units (Ok, I am not certain what lesson you’d ever need Raymond the Seadog to introduce).
- T.D. the Dolphin (Miami Dolphins – NFL)
- Blitz the Seahawk (Seattle Seahawks – NFL)
- Lou Seal (San Francisco Giants – MLB)
- Iceburgh the Penguin (Pittsburgh Penguins – NHL)
- Fin the Whale (Vancouver Canucks – NHL)
- Raymond the Seadog (Tampa Bay Rays – MLB)
- Billy the Marlin (Miami Marlins – MLB)
- S.J. Sharkie (San Jose Sharks – NHL)
- Al the Octopus (Detroit Redwings – NHL)
From what I uncovered, the national basketball association is void of ocean animals as mascots. Please feel free to comment if you can think of another or just let me know if you have a favorite. Lastly, does anyone know where the Phillie Phanatic is originally from?
