Biology 101, Chapter 5b, The 6th Day-Land Animals part 2 {cold-blooded land vertebrates & land invertebrates}

In addition to Biology 101:
Coldblooded Land Vertebrates
• Apologia Biology Exp 13.2, Frog Dissection
• Write about a coldblooded land vertebrate.

Land Invertebrates
• Apologia Biology Exp. 11.3, Earthworm Dissection

♦ Practice a bit of labeling a virtual earthworm.  External and Internal.
♦ Earthworm and Frog Dissection directions at Home Science Tools.

Land Vertebrates - Coldblooded

(1) Frog Anatomy - Part 1 (external)
Please ignore the evolutionary references! Frogs weren't "modified" nor did they need to "adapt" to anything.  God made them the way they are so the first frogs could live and have more frogs.  =)

(2) Frog Anatomy - Part 2 (internal)

(3) Virtual Frog Dissection for those that don't do an actual dissection.
Scroll down and click View Demo.  You will be instructed different buttons to click on.  As you hover over the buttons, the name of that button appears at the bottom of the screen.  Body parts will do the same thing, so you'll know if you are on the right part.
--About 8-10 minutes, depending on how long it takes to locate various body parts.  Longer if you take notes and/or draw diagrams.

Land Invertebrates

Some invertebrates are arthropods.
Arthropod means jointed leg or foot.  Arthropods have an exoskeleton instead of having an inside skeleton.  This means they are also invertebrates - they don't have a backbone.
►Earthworms are invertebrates but are clearly not arthropods, lol.

We already learned about arthropods when we studied the Aquatic and Avian chapters -- the flying insects in the Avian chapter, and the crustaceans (crabs, lobsters, shrimp, etc) from the Aquatic chapter.
But there are arthropods that don't fly and don't live in water.  These are land invertebrates -- insects that crawl rather than fly, as well as spiders, ticks, mites, millipedes, and centipedes to name a few.

►Just to be clear, this section of the chapter is about invertebrates, not arthropods, although I do cover here what arthropods are.

(4) General Characteristics of Arthropods

(5) Insects & Arthropods

One of the characteristics of arachnids is that they have a cephalothorax instead of a separate head and thorax like insects.  So spiders only have two body parts while insects have three.  Insects and spiders both have an abdomen.
(6) Trapdoor Spider

(7) How do Trapdoor Spiders know when prey is near???

(8) Giant Centipede (has 1 set of legs on each body segment)

(9) Millipede (has 2 sets of legs on each body segment)

(10) Leafcutter Ants

(11) Dead Leaf Mantis

(12) Flower Mantis

(13) Javanese Leaf Insect

(14) Earthworm Anatomy

Biology 101, Chapter 5a: The 6th Day-Land Animals part 1 {warm-blooded land vertebrates}

Warm-blooded land vertebrates - mammals!
Thankfully this is a fairly simple chapter since we've just had a wedding January 4!  =)  I have been super busy for the past several weeks!  But it was beautiful and so sweet. =)

I don't have any experiments or class activities, so we will not have class. Therefore I have no extra links to post here.
I did give a few extra assignments.
•Write about one unusual mammal.
•Google to find out how many body systems there are.  List them along with a short description and the basic organs they include.
•Write a couple of sentences telling what the difference is between a body organ and a body system.
Draw and label the basic body organs.

(1) Baby Kangaroo being born

(2) Kangaroos Boxing

(3) The Sloth

(4) Triumph of the Herbivores
Footage of herbivore mammals out-maneuvering their carnivore predators.

(5) Aggressive Nightlife of the Kangaroo Rat
Watch when a snake comes to pay a visit...

(6) Beaver Lodge Construction
The God-given instincts of beavers are amazing!

(7) The Siberian Tiger

(8) Raccoons

(9) Flying Squirrels

(10) Shifak, or Sifaka, (one species of lemur)

(11) Monkey Insect Repellent
Piper leaves have insect repellent properties and protect these monkeys from mosquitoes.

(12) Monkey Alert!
Amazing how different types of monkeys have distinct calls to warn their troop members of an invading big cat predator, and that the different species of monkeys recognize the warnings from the other monkeys. AND that there are different warning calls for each different predator!
