The Life Photo Meme theme this week is Smart.

This is a photo of some brain coral that I took on a dive in Belize, circa January 2006. There are two genra here. In the front is a groove-brained coral (Diploria sp.) and in the back is a boulder brain coral (Colpophyllia sp.). I never could get these two straight during my QUantitative Ecological Survey Techniques course.

They may not be especially intelligent, but I think they look pretty sharp.

The Life Photo Meme theme this week is Free.

My subject are these nuisance little crazy ants that infest many homes (and hospitals) around the world. We’ve had them wandering freely around our house for a season now, despite our best efforts at non-chemical control. We’ve resorted to using a commercial insecticide called Terro®. The ants seem to like it. My identification of these insects is tentative, based on macrographic observations and behavior.


 

Life Photo Meme: Leafhopper

The Life Photo Meme theme this week is Honor an Invertebrate.

So continuing with my mangrove journey from last week, the next creature I came upon was a leafhopper. It was clinging to a mangrove propagule and obligingly held still while I used my little iPhone hack to take a close-up snap.


 

Beach Chair Scientists and Beyond

Beach Chair Scientist
I learned about a new Web site at last month’s NMEA conference called the Beach Chair Scientist. It is run by Ann McElhatton and features a companion blog for “anyone with an enthusiasm for learning about the science behind life in the ocean or along the seashore.” So far there are entries on horseshoe crabs, seaweed and ocean exfoliants.

WATERlog
Another blog I learned about recently is run by The National Aquarium in Baltimore and is called WATERlog. The blog is updated weekly and features posts on their conservation efforts and peeks behind-the-scenes. A recent post featured news of the birth of an Atlantic bottlenose dolphin at the Aquarium. The blog’s sidebar shows photos from the National Aquarium’s Flickr Pool, which gives a personable angle on how the guests view the institution. In contrast, the blog’s About page seems terribly formal, as if it was ripped from an annual report. It does not give a clear idea who the primary author, or authors, are for the site. Compare that to The Monterey Bay Aquarium blog called Sea Notes. They list the authors for each of their posts and I wish the National Aquarium would do this too.

As a side note, the National Aquarium blog is hosted at Wordpress and the Monterey Bay Aquarium blog is on Typepad. For anyone interested in comparing the two hosting services, you can see how these two aquariums take advantage of the different blogging hosts. It is also interesting to note that neither one chose to host their blogs on their own servers.

EcoSRQ
Finally, there is also a new Web site for environmentalists in my area of Florida, called Eco Sarasota. If I recall correctly, this site is an outgrowth of the Sarasota environmental Meet-up group. But just like the National Aquarium site, there is a dearth of contact and background information on who is behind it. Hope they add more info soon.
 

Happy Birthday Snooty, World’s Oldest Known Manatee

Snooty the manatee turns 60 this weekend. Born in captivity in 1948, he is thought to be one of the oldest known West Indian Manatees in the world. He lives just up the street from me, in the 60,000 gallon South Florida Museum Parker Manatee Aquarium.

Manatees and their relatives, the dugongs, are in the family Sirenia, which in turn is a distant relative of the elephants. In addition to sharing the characteristic of longevity, manatees and elephants are some of the largest and heaviest vertebrates. Snooty weighs in at nearly 1300 pounds and is over 9 feet long.

To celebrate, keepers gave Snooty a treat of pineapples and strawberries.

The Hunt for Point-of-Rocks

Point-of-Rocks, Sarasota, FL (060729_por1) [240x180, 24.5K]

David McRee (aka, the BeachHunter) has a new write up of the Point-of-Rocks area of Siesta Key, FL. Readers of this blog know my fascination with the place. Like most of Florida, there are a lot of tacky ads to wade through on the BeachHunter site (and an ocean of matted photos). But the information is thorough and can help you navigate through the half-flower hedges to the best public access beaches.

And why would you want to visit Point-of-Rocks? It’s the only area I know of on the SW coast of Florida that has tidepools.

International Coastal Cleanup, September 15th

2007 International Coastal Cleanup Charts and GraphicsTomorrow is the International Coastal Clean Up Day.

In 1986, a staff member of The Ocean Conservancy was appalled by the amount of trash she found littering the shores of South Padre Island, Texas. She took responsible action by organizing a beach cleanup. In three hours, 2,800 Texans picked up 124 tons of trash from 122 miles of coastline. With that, Ocean Conservancy’s International Coastal Cleanup was born.

That event was just the beginning of a movement for cleaner beaches and waterways. Later, it grew to encompass the shorelines of 25 U.S. states and territories. In 1989, the Cleanup went international, with the participation of residents of Canada and Mexico. To date, over 6 million volunteers have removed over 100 million pounds of marine litter from a grand total of 170,000 miles of beaches and inland waterways.

If you are in my neck of the woods, the Sarasota Bay Estuary Program is having a shoreline restoration at Herb Dolan Park in Bradenton Beach. They need help removing rubble and planting 2600 plugs of Spartina grass. The Eco-Sarasota Meet Up Group is also organizing a cleanup on Otter Key.

Jaehyung HongAnd here is a funny idea from Jaehyung Hong mentioned over at Yanko Designs that is supposed to get kids excited about conservation. It is a piece of plastic that you stick other pieces of plastic into and is vaguely shaped like an octopus. But it seems a bit daft to me. There are only six openings for the legs.

1 Drop of Blood in a 1000 Drops of Water

We had a shark bite in Sarasota Bay recently. A hapless New College student went night swimming and got nibbled on by a (suspected) bull shark. She is expected to recover after receiving several dozen stitches. If you care to see the damage, she has posed for inspection. :shock:

Remarkably, it is only the seventh reported unprovoked1 shark bite in Sarasota County since 1882. These statistics are literally kept on file at the International Shark Attack File. They advise not being in the water during darkness or twilight hours when sharks are most active and have a competitive sensory advantage. Indeed. My buddy SB and I didn’t follow that advice in our undergrad days either. We took a couple turns snorkeling along Lido at sunset. But the severed head of a stargazer and a disemboweled cownose ray were pretty good clues we weren’t alone.

Of course, I kind of like the notion put forth by NBA star Gilbert Arenas. He recently opined that there are no such things as shark attacks:

There are these things called shark attacks, but there is no such thing as a shark attack. I have never seen a real shark attack. I know you’re making a weird face as you’re reading this. OK people, a shark attack is not what we see on TV and what people portray it as. We’re humans. We live on land. Sharks live in water. So if you’re swimming in the water and a shark bites you, that’s called trespassing. That is called trespassing. That is not a shark attack.

A shark attack is if you’re chilling at home, sitting on your couch, and a shark comes in and bites you; now that’s a shark attack. Now, if you’re chilling in the water, that is called invasion of space. So I have never heard of a shark attack. When I see on the news where it’s like, “There have been 10 shark attacks,” I’m like, “Hey, for real?! They’re just running around? Sharks are walking now, huh! We live on the land, we don’t live underwater.”

Perhaps the co-ed would have been less attractive had she slathered on some Shark Defense. This is a new sun tan lotion that purports to also repel sharks. Testing for the product took place at the Bimini Biological Field Station. This is also the location where a classic Mythbusters segment was filmed, one dealing with the notion that sharks can smell one single drop of blood in a thousand drops of water. It’s a shame Discovery hasn’t cottoned on to the idea of letting users embed their video into posts, a la Comedy Central. But you can follow the links below to see how Adam Savage and Jamie Hyneman used condoms and syringes to bust this myth.

Unprovoked attacks are defined as “incidents where an attack on a live human by a shark occurs in its natural habitat without human provocation of the shark.”

New FL Exhibit on Megalodon: Largest Shark that Ever Lived

Backside of a fossil sharks tooth, one of the largest ever excavated in Florida. On display at the Paleo Preserve (www.paleopreserve.org).

The Florida Museum of Natural History will soon open a new exhibit called Megalodon: Largest Shark that Ever Lived

At about 60 feet long, Megalodon was the largest shark that ever lived. The dominant marine predator vanished 2 million years ago, but its story inspires lessons for ocean conservation today.

Visitors enter a full-size sculpture of Megalodon through massive jaws. Once inside, they will discover this shark’s history and the world it inhabited.

The exhibit opens June 16 and runs through January 6, 2008.

Free Seagrass Poster

Seagrass poster [125x162, 20K]Got a chance to see this at FMSEA. Very nice.

The Loxahatchee River District is pleased to announce the debut of its environmental poster series: Seagrasses found in the Loxahatchee River Estuary and southern Indian River Lagoon

The poster provides a way to educate the public about the importance of seagrass and how residents can alter their actions to minimize their impact on seagrass. Through education and awareness, the poster will foster a stronger sense of stewardship for the protection of seagrasses and the Indian River Lagoon. The seagrass poster will be distributed throughout Palm Beach and Martin County schools, environmental centers, and other learning facilities. Funding for this project was provided by the South Florida Water Management District through the Indian River Lagoon License Plate Program.

Growing Ear Spiders

The weird news making headlines recently is the true story of a Oregonian boy who had a pair of spiders living in his ear. But this got my own spider-sense tingling, because that is a pretty tight space for even the tiniest chelicerates to co-habitate. Rather, I suspected that there was only one spider that had molted while in the boy’s head. And sure enough, if you watch the video at CNN, it certainly seems that way. The actual spider is denser, and sitting at the bottom of the jar. The shed skin is lighter and floating. So instead of two spiders in his ear, he had just one that was growing bigger. Not sure which is worse.

But how did the critter get in there? Well, I once heard an interesting anecdote from an arachnologist. He postulated that we are never more than eight feet away from a spider at any given time, even in the cleanest of buildings. They are just all around us.

UPDATE: Seems that Straight Dope agrees with me.

Florida Marine Science Educators Association Conference, 2007


I will be attending the FMSEA 2007 Annual Conference this week in Naples. My presentation notes and updates will be posted here. Not sure about connectivity, but I will update as much as possible.

PBS Special: Journey to Planet Earth - State of the Ocean’s Animals

PBS is airing its tenth installment of Journey to Planet Earth series tomorrow. The show is hosted by Matt Damon, which is kind of annoying. Expect a disheartening survey of the many ills facing our planet’s oceans interspersed with optimistic words about mankind’s resourcefulness and the hope that technology and international cooperation will someday solve all these problems.

STATE OF THE OCEAN’S ANIMALS
Premiers March 28th, 2007 at 8pm on PBS
Check local listings

Nearly half the world’s marine animals may face extinction over the next twenty-five years. Global warming, over-fishing, and habitat destruction are emptying the world’s oceans. Join host Matt Damon as “State of the Ocean’s Animals” takes a hard look at the future of our watery natural world: the beauty, the incredible animals, and the dangers that threaten them.

Features scenes from the Pacific Northwest (whales, salmon and sea otters), Florida (sea level rise and its effect on loggerhead turtles), Japan (the slaughter of dolphins), China (shark fin trade), and the Antarctic (threats to Emperor Penguins).

Florida mystery squid revealed

Asperoteuthis acanthoderma, squid [200x150, 8K]A Mote scientist received an unidentified floating object (U-FL-O?) last week. It was a squid found at the surface by a sharp-eyed fishing captain southwest of Key West last Tuesday. The story made the news and now there are some updates. There is still a chance it is a new species but all the major characteristics point towards Asperoteuthis acanthoderma.

A. acanthoderma reaches a rather large size. The largest specimen known has a mantle length of 78 cm and long, slender tentacles. In one squid (45 cm ML) the tentacles were over 12 times longer than the mantle (i.e., about 5.5 m) (Tsuchiya and Okutani, 1993). The most distinctive feature of this species is the presence of very small, pointed cartilagenous tubercules over the surface of the head, mantle and arms.

The really interesting thing is that if this is A. acanthoderma, then it may be the first time it has been documented in the Atlantic Ocean. Up until now, all specimens have been found deep in the Pacific. So where has this one been hiding? How did it get here? Many mysteries remain.
