5. We chose to spotlight Florida animals because The Ogburn School is located in Florida. Your next assignment is to conduct an internet search to discover information related to animal diversity. You may choose to research animals in the state you live in. If you live in Florida you may choose to research a Florida endangered species, or one from another state or country. Your research must include the following:
a. species of animal
b. location of animal (state or country)
c. the animal\'s status (extinct, endangered, threatened, etc.)
d. reason for status (why is animal extinct, endangered, threatened, etc.)
e. type of habitat needed for survival
f. conservation efforts on the animal\'s behalf
g. prospects for the future of this animal
alveolus (alveoli, plural) The depressions or sockets in the tooth-bearing skeletal elements such as maxillae and dentaries into which the roots of the teeth are inserted. Especially well developed in mammals and crocodilians.
amniote A member of the taxonomic group Amniota, such as reptiles, mammals, and birds, characterized by possession of the amnion, a specialized embryonic membrane.
arboreal Descriptive term for an animal that primarily lives in trees.
astragalus (also talus) Bone that articulates with the tibia and fibula to form the ankle joint.
atlas The first or anteriormost vertebra of a tetrapod, the one that articulates with the skull.
auditory bulla (auditory bullae, plural) The bone that encloses the inner ear region of the mammalian skull and is found on the ventral surface of the posterior region of the skull. Typically fragile and thus rarely preserved in fossils; but inflated and composed of very solid bone in whales. For that reason, whale auditory bullae are commonly recovered as fossils. Alternatively called the tympanic bulla.
autochthonous In paleontology, used to describe a taxon or clade that evolved frim its common ancestor in its present geographic region.
axis (axes, plural) The second vertebra in a tetrapod, it follows the atlas.
