Nine-banded Armadillo

Dasypus novemcinctus


Description: head and body to 17 inches, tail to 16 inches; upper body tan to gray with bony plates on shoulders and rump with nine flexible bands in the center; tail composed of 12 rings (second photo); bony plates don't protect directly against predators which can bit through it but do protect animal from thorns and other sharp plant material so it can move quickly through thickets and undergrowth to escape predators; long snout and tongue; hairless on top but a few white hairs on belly; poor eyesight but well developed senses of hearing and smell

Food: 93% of diet is animal such as grubs, insects, and other invertebrates; also eats berries and fungi

Habitat: determined by texture of soil it burrows in-- if soil too hard, armadillo unable to survive; prefers sandy soil with dense cover; primarily nocturnal but may be seen during day, especially in colder months; an accomplished burrower that can begin digging and be out of sight in seconds

Range: entire state

Voice: mostly quiet but does grunt

Breeding: male and female pair up for one breeding season at end of July or August; pair shares one den 7-8 inches in diameter and up to 16 feet long; embryo floats free in uterus, remaining dormant until November; four young of same gender develop from single egg and share placenta (identical quadruplets); young born in March-April fully formed, open eyes, and can walk within hours; nurse for about two months but stay with mother for several more; young ready to breed following summer


 

Florida Black Bear

Ursa americanus


Description: length to 6 feet, height at shoulder to 3 feet; adults range in weight from 150 to 500 pounds or more; adult females average about 180 pounds, adult males about 300 pounds; coats mostly black with a brown muzzle, although backs may be brownish (adult female, top photo); cubs almost all black except for muzzle (middle photo)

Habitat: in whatever habitat provides suitable food and habitats may change with seasons; prefer thick swamps, forested areas with dense understory, pine flatwoods, sand pine scrub; marks home range by clawing boundary trees; primarily active in day but may become nocturnal in areas around human activity

Range: entire state; average home range for adult male is about 50 square miles, adult female about 10 square miles; male and female territories may overlap but same sex territories don't; young males and females with cubs frequently wander into more urban developments where won't encounter adult males

Voice: variety of huffs, grunts, and whines; young cub calling for mother sounds almost like human infant crying

Breeding: mate from May to July; females breed for first time at 3-1/2 years of age, give birth at 4, then tend to reproduce every other year as long as nutrition is adequate; usually two cubs born January or February; cubs stay with mother for up to 18 months; mother doesn't hibernate but creates den-like nest in thick palmetto and goes into stupor in spring when cubs born (called "denning")

Notes: excellent tree climbers; cubs often sleep and rest in tree tops; adults climb trees for food (figs, bees/honey, grubs in dead limbs); bears usually solitary and timid, but mothers fearless when protecting cubs; have excellent senses of smell and hearing but are a little nearsighted; often stand on hind legs to see and smell more accurately
