Now Thats a Seed Pod
This is a gigantic seed pod that I found left on a sidewalk. It is enormously huge! This was from a tree, but we do not know what or where it came from. I got scraped on the nose on the front porch of another house, but my nose is fine now!

Bats
This is a picture of a fruit bat. The way you can tell between a vampire bat and a fruit bat is that vampire bats are very freaky and fruit bats are very cute. Fruit bats are also completely black and vampire bats are kind of tan. We found this next to our house one afternoon. Something cool- it has 5 fingers just like humans. When my mom started taking pictures of this bat, it started crawling. I wasn't really scared, but my mom was!

Catepillars
This is a picture of clear-winged butterfly caterpillars. Sometimes the butterflies are yellow. Some of these are caterpillars that have just hatched. The little bits that are in my hand are poop from the caterpillars. I found them in the garden at a neighbors house.
Field Notes:
For More information on Clear- winged butterflies look here.
We have not been able to positivly identify this caterpillar as that of the clear-winged butterfly. The boys around here have named it as such. If anyone can help it would be greatly appreciated.

Toad-O-woad-A
This is a picture of a toad in my hand. The white stuff that is coming out of his skin is actually poison. There is a bump behind its eyes that shoots the poison out when its afraid. The toad may not look like its afraid, but it really is. The toad uses this to protect itself. If you look down in the middle of the toad's backbone. This toad has yellow cat-eyes and little horns above its eyes.
Field notes True toads are widespread and occur natively on every continent except Australia and Antarctica, inhabiting a variety of environments, from arid areas to rainforest. Most lay eggs in paired strings that hatch into tadpoles, although, in the genus Nectophrynoides
Nectophrynoides

the eggs hatch directly into miniature toads. True toads are toothless and generally warty in appearance and have a pair of parotoid gland

s on the back of their heads. These glands contain an alkaloid poison which the toads excrete when stressed. The poison in the glands contains a number of toxins causing different effects. Bufotoxin
Bufotoxin
Bufotoxins are a family of toxic substances found in the parotoid glands, skin and venom of many toads ; other amphibians; and other plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain: 5-MeO-DMT, bufagins, bufotalin, bufotenine,...
is a general term, different animals contain significantly different substances and proportions of substances. Some, like the cane toad Bufo marinus, are more toxic than others.

Male toads possess a Bidder's organ The Bidder's organ is a spherical, brownish organ in any member of the family Bufonidae, or simply, toads. The organ is located just in front of the kidney, or, mesonephros. It is formed at the cranial tip of the male and female gonad during the larval stage. Normally it is inactive and contains miniature follicleFollicle

s which have the capability to mature (becoming active). Under the right conditions, the organ becomes an active ovary and the toad, in effect, becomes female. (This is similar to the gender-changing frogs described in Jurassic Park
