Query: Ecological notes on the Annulated Treeboa (Corallus annulatus) from a
  Costa Rican Lowland Tropical Wet Forest   The Annulated Treeboa (Corallus annulatus) is one of nine currently
recognized species in the boid genus Corallus. Its disjunct range extends from
eastern Guatemala into northern Honduras, southeastern Nicaragua, northeastern
Costa Rica, and southwestern Panama to northern Colombia west of the Andes. It
is the only species of Corallus found on the Caribbean versant of Costa Rica,
where it occurs at elevations to at least 650m and perhaps as high as 1,000m.
Corallus annulatus occurs mostly in primary and secondary lowland tropical wet
and moist rainforest and it appears to be genuinely rare. Besides C. cropanii
and C. blombergi (the latter closely related to C. annulatus), it is the rarest
member of the genus. Aside from information on habitat and activity, little is
known regarding its natural history.
