Musical Notes:

Octopus’s Garden is a fabulously sweet and silly song by The Beatles.  According to Wikipedia, “The idea for the song came about when Ringo Starr was on a boating trip with his family in Sardinia in 1968. He ordered Fish and Chips for lunch, but instead of fish he got squid (it was the first time he’d eaten squid, and said “It was OK. A bit rubbery. Tasted like chicken.”) Then the boat’s captain told Starr about how octopuses travel along the sea bed picking up stones and shiny objects with which to build gardens. Starr said that hearing about octopuses spending their days collecting shiny objects at the bottom of the sea was one of the happiest things he had ever heard, inspiring him to write this song.”

“Stinging Nettle” is a song by the band, Calexico.  This song is found on their first album titled Spoke, which was released in 1997.  At the time, their band name was still Spoke so technically, it is a self-titled album.  This song features the quiet beautiful and eerie side of Calexico.

They’re all the same organism!  Crayfish are not a fish at all.  They are Arthropods that belong to the subphylum Crustacea.

This shows all the different types of appendages.

Here are some videos from our class dissection:

Crayfish gills

Internal structures

And here’s one of the a crayfish molting.  It’s a long video (it finishes molting at 4:30)

Arthropod means “jointed limbs.”

These are examples of arthropods from each subphylum.

Subphylum Trilobitomorpha- an extinct subphylum-flourished from around 540 million years ago to 280 million years ago.

Subphylum Chelicerata- They all mash up their food with dagger-like chelicerae which are literally "claw horns."

Subphylum Chelicerata- This is a horseshoe crab. Cool fact: They do not have hemoglobin like us. They have a compound called Hemocyanin which turns their blood blue when it is exposed to oxygen.

Subphylum Crustacea: Pollicepes polymerus- These are found in the high intertidal zone on the California Coast.

Subphylum Crustacea: Try to find the crab! It's a decorator crab which attaches anemones and coral polyps for camouflage.

Subphylum Myriapoda: Centipede means "hundred legs"

Subphylum Insecta-There is an estimate of six to ten million species!

Here’s a video that explains the “waggle” dance of a honey bee.

And here’s a video that shows some unique bees…

Flatworms!

Our friend the Planaria

Marine: Orsaki Flatworm - Maiazoon orsaki

Marine: Pseudobiceros gloriosus

Marine: Pseudoceros zebra

This head has hooks to hang out to the host's intestines. Clever, huh?

**Please note: They do NOT have a coelom! I got it wrong in the notes. Other bilaterally symmetrical organisms tend to have coeloms, but not these guys. They do have a single opening that functions as both the mouth and anus. Yum! Most platyhelminthes also have a series of specialized organs called protonephridia (“first kidney”) which help to filter waste out of their bodies.

This video shows the mouth/anus (pharynx) really well:

This is a land planarian:

Now, I’ve watched lots of gross movies with parasites/ worms in your face/ tapeworm….this one is pretty mild. It’s a fluke that is living in a minnows eye.

The wonderful world of sponges!

Sponges are considered the oldest living animal phylum. We may have originated from a sponge!  The name Porifera means “pore bearer” in Latin. Sponges are the only animals that if broken down to the level of their cells can miraculously reassemble and regenerate themselves.  They filter water to harvest small amounts of microscopic food.

Here’s a video showing the filtering process in action:

And since sponges are animals…they reproduce with sex cells.  How?

Guava Jelly

“Rock Lobster” is a song by the B52′s.  It was released in 1978.  This fun song contains superficially nonsensical lyrics about a beach party and excited rants about real or imagined marine animals (“There goes a dog-fish, chased by a cat-fish, in flew a sea robin, watch out for that piranha, there goes a narwhal, here comes a bikini whale!”)

Here are color pictures of the two mammals on p. 233 for your homework.

Musical notes:

“Kingdom Rise Kingdom Fall” is a song by the Wailing Souls.  According to their website, “Fusing the harmonies of Motown with the Roots and Dancehall sounds of reggae, The Wailing Souls have ridden the crest of Jamaica’s music for more than four decades.  The Wailing Souls are part of the small surviving group of Reggae and Roots originators still musically active today. The legendary group dates back to the late 1960′s.”

Animal Collective is a musical collective orginally from Baltimore.  Their style of music is often referred to as noise pop, although I would describe it as “The Beach Boys floating in a fog with neon lights flashing everywhere” music.  Do you know what I mean?  Anyway, here’s a sample and a link to their new video for My Girls on their website.

These games come from a site called “The GEEE! in Genome”

Science education is full of nerdy puns.  Anyway, these games are pretty fun.  Some are better than others but they are all fairly short.
