20 reasons oysters are awesome

O-Y-S-T-E-R! Happy National Oyster Day! There needs to be much love for the oyster. These creatures are delicious, sustainable, and help the environment. Maybe we need more than just one day to celebrate this bivalve? If you don’t believe me, here are over 20 reasons oysters are awesome:

  1. Oysters spawn during the summer months and therefore tend not to be as tasty. This is the epitomes of the old wives’ tale on why “you shouldn’t eat oysters in months that don’t end in ‘R’.”
  2. Another reason this adage has prevailed is that oysters are much better when cold and do not taste that good when in the heat.
  3. Oysters can change their sex. They can produce both semen and eggs.
  4. Oysters have been known to live up to twenty years in captivity.
  5. When oyster larvae attach to a hard material, a vital part of their life cycle, they’re called “spat.” Two to three years later they are considered adults.OystersLifeCycle
  6. The habitat of the Eastern American oyster (Crassostrea virginica) extend from Canada to Argentina.
  7. Even though there are countless (and delicious) varieties of oysters there are only five species. These species are the Pacific oyster (Crassostrea gigas), Kumamoto oyster, European flat oyster, American (i.e., Eastern) oyster, and the Olympia oyster. The shells of the five species are truly what sets these species apart (other than the geographic region they are most often found). The American is pretty familiar with its large size and comma shaped shell. The Olympians have a small, round, pale shell with lustrous coloring. The Kumamotos have a round, pale shell as well but not as much of a smooth shell. The European flat has fine ridges around its large, straight shell, and the Pacific are small with wavy shells. In fact, the same type of oyster can taste different contingent on where it was raised.IMG_7313
  8. Sometimes a bacteria that commonly grows along coastal environments where oysters are found known as Vibrio vulnificus can infect the oysters. This would leave to that “bad oyster” that might make you sick.
  9. One very common misunderstanding of the oyster is that they are an aphrodisiac. However, it’s really just their significant amount of zinc. Zinc is a mineral that will boost your energy and therefore can boost your sex drive. Other benefits of zinc are that skin will improve and make your bones stronger.
  10. Oysters also have immense amounts of omega-3-fatty acids which can sharpen your memory, lower levels of depression and heart disease, as well as a host of other benefits.
  11. Oysters also have lots of vitamin A, C, D and B-12.
  12. Even though Boticelli’s “The Birth of Venus” has Aphrodite rising from the sea on a scallop shell legend has it that the Goddess of Love, Aphrodite, emerged from the sea in an oyster shell.
  13. In the 17th century, New York City was covered in oyster beds and were very much enjoyed by the native Lenape Indians. Eventually, by the 19th century, the oysters were so plentiful that raw oysters could be purchased from the street vendors. There was even oyster saloons with all sorts of methods for consuming oysters.
  14. Most pearls found in jewelry are from clams and mussels – not oysters. Although, there are also actual pearl oysters which are from a different family of bivalves.
  15. Oyster mushrooms and black salsify, also called “vegetable oyster”, actually taste like oysters.
  16. Oysters are a crucial member to the aquatic communities. Not only do they gobble up lots of algae (think of your back bay becoming a dirty fish tank without them), but they are crucial as natural filter feeders. Oysters filter approximately 30 to 50 gallons of water a day removing excess nutrients and allowing shrimp, clams, crabs, and snails to flourish. The cleaner water also enables more seagrass to grow creating more habitat for fish.
  17. Oysters grow on top of one another as an oyster reef. These huge substrates are imperative for soil erosion and shoreline stabilization.Oyster_human_impact_diagram_SM_noaa
  18. If you bring home oysters for your next bake be sure to recycle the shells close to home. The shells of the oysters are extremely rich in calcium and can help balance the pH of the soil as well as add nutrients to your garden. Fertilizer fresh from the sea!
  19. Oyster farms, unlike other types of fish farming, can greatly enhance the health of nearby waterways. Not only do they tend to munch on pollution (yes, they’ve been known to help out Big Oil), but if the oyster were to escape it isn’t in danger of becoming an exotic species.
  20. While it’s all well and good that farmed oysters can do a lot to help water quality … natural oysters reefs are just as vital. Unfortunately, 85% of the global oyster reef population has been lost.
  21. In the Chesapeake Bay an estimated 2,600 acres of oyster beds are lost each year because of runoff and silt. On the Pacific coast invasive crabs and snails are destroying natural oyster beds.
  22. Not only are oyster reefs vanishing, but the ones that remain are just not as strong due to ocean acidification (i.e., climate change for the sea).
  23. There are many organizations along the Atlantic coast that are looking for volunteers to help adopt and raise oysters. If you don’t live on the water volunteers are still urged to build oyster reef substrates or oysters mats.

Are we breaking up with Mother Nature?

Has it gotten to the point that when you do connect with Mother Nature it seems like an awkward hug? It’s been said time and time again that we’re better off taking a step away from technology to reconnect with Mother Nature as a regular part of our daily lives.

The benefits of establishing a relationship with Mother Nature are tremendous. Kids will grow more confident and be better critical thinkers when they are  trusted to play outside and explore, their vocabulary will increase exponentially once they’re not staring at a television set for more than two hours a day, Americans of all ages will not be as obese or depressed if we get off the couch and get outside. But, as we know from the countless authors that have documented the benefits to getting outside and into nature (Louv, Ratey, Sampson) there are also significant challenges. Isn’t that always the case when one is reconnecting with a long-lost family member?

There are so many reasons not to bother. I hear quite often that, actually no – strike that … I find myself saying these things all too often … “The modern suburbs are designed with cars in mind.” “It’s a different world than when I was a kid and there is increased risks with having your children wander off.” “I live somewhere that is quite different ecologically than where I grew up and I am scared of the unknown.” “I work full-time outside of the house and the weekends are fairly structured.” National Wildlife Federation has even been posting recently how “we are a nation of people who are afraid of the outdoors.” But, the authors I mentioned above aren’t pulling this out of thin air and aren’t specifically talking about the importance of nature’s impacts on children.

Who am I kidding though? Like any relationship … reconnecting cannot be forced. However, it is going to take initiative on our part as parents. I plan to do it with lots of baby steps.  If you, the reader of this post, are inspired to get outside and let go more there is a high likelihood that curious little minds will follow. And, in an effort to spark some motivation here is a listing of some fun ways to wander through a favorite secluded spot.


What are some of your challenges in getting outside and wandering aimlessly? Where are your favorite spots to wander?


Marine Mammal Monday: The Marine Mammals of Virginia

From Robert A. Blaylock of Virginia Institute of Marine Science (VIMS) (thirty years ago!) is a pretty fun guide to look through if you’re into historical documents. Yes, that would be me. It is not very up to date on endangered species listing, but was does a fantastic job setting out on its intention “To aid citizens in identification, this guide describes the natural history of marine mammals. This guide is organized by taxonomic orders and families; within a subfamily, species are listed by their frequency of appearance in Virginia waters. Space limits descriptions of the species’ habitats and distributions to the western North Atlantic.”

Eight citizen science projects for your day at the beach (one for every day of your beach week + a bonus)

Do you have one (or several!) of those kids just itching to be future marine scientists? It’s time to take the beach day up one more notch. Here are some citizen science projects that will definitely be lots of fun for the whole family. Trust me … they’re free and easy!

Field Photo: The Field Photo App allows you take photos during your trips to the beach (or even field trips) and geotag them and add metadata and field notes to the photos. The field photos are then uploaded where people share, visualize and archive field photos that document land use and land cover change, flood, drought, fire, and so on.

Great Eggcase Hunt Project: The Great Eggcase Hunt aims to get as many people as possible hunting for eggcases that have either been washed ashore (or are found by divers and snorkelers underwater). The empty eggcases (or mermaid’s purses) are an easily accessible source of information on the whereabouts of potential nursery grounds and will provide the Trust with a better understanding of species abundance and distribution. While it originated in the UK over a decade ago, The Shark Trust has been collecting data in the US since 2003.

Jellywatch: Have you seen a jellyfish, red tide, a squid, or other unusual marine life recently? If so, tell them about it! Marine biologists need your help to develop a better understanding of the ocean. You can help us even more by submitting a picture of what you saw!

Marine Debris Tracker: The simple tool allows users to report the type of debris and its location through GPS features pre-installed on a cell phone. (Check out this list of apps for the beach, too!)

Osprey Watch: OspreyWatch is a global community of observers focused on documenting breeding osprey. There is no charge to participate and we welcome new volunteers to the program.

Ringed-Billed Gulls: In 2013, researchers from MIT and the Massachusetts Department of Conservation and Recreation started using the same scheme as the project originators in Canada using blue or red plastic bands and 3 codes to band ring-billed sea gulls. Nearly 700 birds have been marked.

If you observed one of these banded gulls, you can report your sighting using an online form.

Secchi Dip-In: The Secchi Dip-In is a demonstration of the potential of volunteers to monitor and gather environmentally important information on our lakes, rivers and estuaries. The concept of the Dip-In is simple: individuals in volunteer monitoring programs take a transparency measurement on one day during the month of July (but, they accept data after the deadline as well).

Wildlife Health Event Reporter: The Wildlife Health Event Reporter allows you to observe and record events that may identify important changes in the environment. It’s an experimental tool that hopes to harness the power of the many eyes of the public to better detect these changes.

Marine Mammal Monday: Test your knowledge of state symbols

Can you match the state with the marine mammal "symbol"?

Can you match the state with the marine mammal “symbol”?

Download the pdf here. I’ll post the answers next Monday. First person to comment with the correct answers (here or on Facebook) I’ll send a copy of the Smithsonian’s Whales, Dolphins and Porpoises (Flexibound).

Also, if I’ve missed a state with a marine mammal “symbol”, please don’t hesitate to let me know.
