"Can mammals talk?"

Presently, no extant mammalian species is capable of verbal articulation using any known or current dialect. However, there are some slight exceptions to this, pertaining to...


 * intraspecies communication / vocalization
 * types of vocalizations (e.g. mating, territory defense, threat warning, etc.)
 * links to examples or alternative wiki pages
 * few examples of primates having been successfully taught ASL to effectively communicate with caretakers

Squalidae
Edits to be made to introduction of Squalidae page:

Introduction

 * "no anal fin," yet picture of spiny dogfish depicts clear pelvic fins (plural, as in ventral pair similar to pectoral fins, but smaller in size and located towards caudal end). Although internal wiki (see Fish fin page) does elaborate on different kinds of fins, personally I think further clarification concerning difference between pelvic and anal fins should be included in the intro to avoid confusion between the two as said image may be partially misleading.
 * remove "tend to have" slender bodies - all dogfish species have streamlined body morphology
 * remove "known to be" - In comparison to other shark species, dogfish are smaller and more compact in size
 * Add Squaliform order comprised of 7 families (see List of sharks page for all), including Squalidae. Squalidae family itself contains only two major genera: Cirrhigaleus (3 species) and Squalus (34 species)
 * "Dogfish sharks earned their name... dog-like packs" should probably be moved into beginning of intro as somewhat informal / less important information (^ after "119 species" and before "they have two dorsal fins...")
 * Once group members have their drafts ready, be sure to include brief description of what their subsections cover

Body
Edits to be made to body of Squalidae page:

Taxonomy
Create Section: breakdown of Squalidae scientific classification including...


 * all families & descriptions of each
 * all genus of each family & descriptions
 * potential color-coded chart?
