For our endangered species of the week, I’m rerunning an earlier post about a very “Halloweeny” species – the Kauai Cave wolf spider! So read through and then learn 7 facts about spiders that you might not have known!
The Kauai Cave wolf spider (Adelocosa anops), also known as pe’e pe’e maka ‘ole in Hawaiian (from Earth’s Endangered Creatures) is found in only three caves on the Hawaiian island of Kauai. Like other wolf spiders, the Kauai Cave wolf spider doesn’t build a web to capture prey; it relies on speed and chases down its prey. Like all other spiders, it is venomous; it has three teeth for biting it’s prey. What’s really amazing about this hunting style is the fact that these spiders don’t have eyes (from Arkive)! According to the U.S. Fish and Wildlife Service Species Action Plan, the main threats to the spider are alteration of the caves and surrounding vegetation, non-native predators, and pesticide run-off.
So really, who cares? It’s just one little spider in a few caves in Hawaii. The answer is: when we protect these little spiders, we help ourselves. If pesticides from agriculture are bringing these spiders near extinction, there’s a pretty good chance those pesticides in water run-off are also affecting human populations. It’s in our best interest to clean up the water – the spiders win and humans win!
Seven Spooky Spider facts!
- North America is home to over 3,000 of the approximately 40,000 species of spider worldwide!
- The largest spider is the Goliath Bird-eating Tarantula, which can grow as large as a small dinner plate! Check out this National Geographic video: http://video.nationalgeographic.com/video/animals/bugs-animals/spiders-and-scorpions/tarantula_goliath/
- Spiders are not insects – they’ve got 8 legs and 2 body parts (as opposed to insects with 6 legs and 3 body parts)
- Spiders don’t have internal skeletons – they’ve got exoskeletons made of chitin (the second most common carbohydrate on Earth!)
- Some spiders spin webs each day and eat them at the end of the day to recycle the protein in the strands!
- Pound for pound, spiders’ silk is one of the strongest fibers on Earth!
- Spiders have been sent into outerspace! For more information on these “spidernauts”, see NASA’s website. Check out Esmerelda as she dines at zero-gravity on the international space station!

Here’s a tasty recipe for cool fall nights – we’re planning to have it on Halloween night! Not a quick recipe, but the end-result is filling and a crowd pleaser. I adapted this recipe from one found in the November 2013 issue of Cooking Light.
4 cups veggie broth
2 cups water
12 slices Morningstar Farm veggie bacon strips, microwaved to crunchy
2 tblsp olive oil
1 cup chopped onion
1 tbsp thyme
3 tsp jar garlic
8 ounces sliced cremini mushrooms
8 ounces sliced shitake mushrooms
1/2 tsp salt
2 cups uncooked barley
3 ounces shredded Gruyere cheese
1/2 cup chopped, drained oil packed sundried tomatoes
2 tsp soy sauce
1 tsp pepper
1 (10 oz.) package frozen spinach, thawed
- Preheat oven to 375 degrees
- Combine water and veggie broth and warm in a large pot
- Heat olive oil. Saute onion, thyme, and garlic until onion is soft. Add mushrooms and salt and cook until the mushrooms are soft (about 10 minutes).
- Stir in barley and cook for about 1 minute.
- Add 2 cups broth and cook until almost absorbed. Continue to add broth mixture, one cup at a time, until broth is absorbed and barley is soft.
- Stir in 1/2 Gruyere, tomatoes, soy sauce, pepper, spinach, and crumbled “bacon.”
- Place barley mixture into a greased glass baking pan. Sprinkle remaining cheese on top.
- Cover with aluminum foil and cook for 15 minutes. Remove foil and cook for another 10 minutes.

My students were asking a lot of questions this week about reptiles and their brain power, so I’m reposting this article about the Komodo dragon (Varanus komodoensis). Found in the wild on a few volcanic islands in Indonesia, this largest of all reptiles (with large individuals weighing over 150 lbs) will eat almost any type of meat. It is endangered (population is estimated at 3,000 to 5,000 individuals) because of its limited range, lack of egg-laying females, human encroachment, and natural disasters. Since it’s a top predator in its habitat, the Komodo dragon plays an important role in keeping the ecosystem in balance.
Here are 8 more really cool facts about Komodo dragons:
- Komodo dragons can see their prey at great distances – over the length of a football field!
- Komodo dragons only have light sensing cells called “cones” in their eyes – no “rods”. “Cones” help animals see color and in bright light, while “rods” help animals see in dim light. So if you’re going to avoid the gaze of a Komodo dragon, do so at dusk.
- Komodo dragons have a terrific and unique sense of smell, much like a snake’s. Check out this description from the National Zoo (2013): “It uses its long, yellow forked tongue to sample the air, after which the two tongue tips retreat to the roof of the mouth, where they make contact with the Jacobson's organs. The chemical analyzers "smell" a deer by recognizing airborne molecules. If the concentration present on the left tongue tip is higher than that sampled from the right, it tells the Komodo that the deer is approaching from the left. This system, along with an undulatory walk in which the head swings from side to side, helps the dragon sense the existence and direction of odoriferous carrion from as far away as 2.5 miles (four km), when the wind is right.” So maybe trying to avoid Komodos at dusk won’t work out so well……
- Komodo dragons have both venom AND over 50 strains of bacteria in their saliva – good for bringing down prey.
- Komodo dragon venom is not toxic to other Komodo dragons!
- Komodo dragons can eat up to 80% of their body weight in one feeding!
- Komodo dragons can run up to 13 mph!
- Komodo dragons can be playful and have different personalities! Don’t believe it? Check out this article in Zoogoer magazine.
But wait, there’s more! If you’d like to learn more about these fascinating creatures, check out the National Zoo fact sheet.

In my previous post about the state of birds in the world, the video interview mentioned that we’ve already lost 10 bird species in Hawaii to extinction – a sad report indeed. So I figured I’d share with you a teeny, tiny, thin silver lining on climate change and species survival. In September, the Washington Post reported on a study by researchers at Dartmouth College and UVA. These researchers found that some species of lizard seem able to adapt and function at higher temperatures. Previously, researchers didn’t think tiny lizards could adapt their behavior so quickly to changes in temperature, but they found evidence that little brown anolis in the Bahamas can adjust.
Just figured you might need a little mid-week environmental silver lining! (photo: Christian Cox, Washington Post)

1 cup heavy whipping cream
1 tblsp dijon mustard
1/2 tsp salt
1/4 tsp nutmeg
1 cup shredded swiss cheese
1) Heat oven to 375 degrees (but just for a couple of minutes!)
2) Heat oil in a large frying pan over medium heat. Add onions and cook until browned and soft (stir once in a while), about 30 minutes.
3) In a bowl, whisk together eggs, milk, mustard, salt, and nutmeg. Remove pie crust from freezer, and sprinkle cheese evenly on bottom of crust. Spread onions on top of the cheese. Pour egg mixture over cheese and onions. Bake quiche for 45 minutes or until eggs are set.

Since this week’s earlier post was about birds, I figured I’d use this past post for TBT AND Halloween! Enjoy!
Since September 1, 2012 (and Sept 6, 2014), was International Vulture Awareness Day, this week’s endangered species is a group of animals – the vulture! While some species populations, like the King Vulture (Sarcoramphus papa) pictured here, are doing well, other species populations, like the California Condor (Gymnogyps californianus) and theAndean Condor (Vultur gryphus) are less secure. These massive birds are nature’s waste management experts, cleaning areas of dead and rotting carcasses. Their bodies are specially adapted for this task with their bare heads and strong beaks.
California condors are one of the best known survival stories in conservation biology. These spectacular birds, with wingspans of up to 10 feet, can soar as high as 15,000 feet! In the 1970s, the population dwindled to only 2 or 3 dozen birds, and then dropped to only 10 birds in 1987. Since the birds don’t reach sexual maturity until 6 to 8 years of age, and then they breed slowly, recovery of the species was difficult at best. Through the persistent work of endangered species biologists, reintroduction of the birds began in 1992 and now 127 individuals live in the wild. The Andean condor population is doing better than its California cousin, with a few thousand individuals found in the wild. Like the California condor, it’s a slow breeder and a vital link in the food chain (info from National Geographic). It’s probably the vulture with which you’re most familiar, because it’s the one that looks like it has a white, fur collar around its neck.
So get out there and celebrate Vulture Awareness Day – without scavengers our world would be A LOT messier!
