The Northern Banana Salamander (Bolitoglossa rufescens) also known as Common Dwarf Salamander or Rufescens Salamander is a species of salamander in the Plethodontidae (lungless Salamanders) family. It is found in the Atlantic slopes of Meso- America from San Luis Potosi, Veracruz, North Chiapas and Mexico continuing on to the southern part of Guatemala, Belize, and northern Honduras. Species of genus Bolitoglossa are commonly known for their characteristic mushroom shaped tongue and the ability to project their tongue a considerable distance to capture prey.

Description and Ecology
The Northern Banana Salamanders are small terrestrial, arboreal salamanders. Their size ranges from 35-36mm SLV and 65-70mm TL. It dwells in tropical and subtropical moist lowland rain forests and mountain ecosystems, as well as in citrus orchards, banana plantations, and pine plantations. Predominantly found in bromeliads in tropical and subtropical wet forests. B.rufescens is dorsally pale brown to tan brown in color and on paler species it may consist of dorsal longitudinal streaks or specks. The ventral area in most species is grey or paler than the dorsal color, in some the coloring might be uniform. A dark brown streaks usually runs from behind the eyes and extend towards is posterior, it may go as far as half the length of the body or farther. Northern Banana Salamanders are rather small in size when compared to other salamanders in the same Bolitoglossa genus such as the O'Donnell's Salamander (Bolitoglossa odonnelli) which are longer in length. The Northern Banana Salamander has a robust body with ll costal grooves running longitudinally between its legs and 3 additional costal grooves in between their limbs. This grooves assist salamanders in water transportation, enhances respiration and aids in thermo-regulation. They possess webbed fingers and toes, with 4 digits on its front limb and 5 digits on its hind limbs. Its snout is truncate and slightly projected on its anterior dorsal view. This species are lungless salamanders, they lack lungs and breath entirely through their skin and lining of their mouth.

Diet
Salamanders mostly feed on small invertebrates found on forest floor. Diet is influenced by size and micro-habitat of the salamander. Bolitoglossa rufescens are small and strictly arboreal, research shows that their diet is comprised significantly of ants(Hymenoptera: Formicidae)followed by beetles and weevils Coleoptera,Collembolan and Arachnids.

Behavior
Snakes are major predators of salamanders they sense their prey by flickering their tongue in the air or by direct contact with prey or substrates. Anti-predator behavior studies show that Bolitoglossa rufescens responds more often to predator attacks that involved stimulation to the head other than its the tail or trunk area. It responds by elevating or elevating and undulating its tail.
