Interim profile, incomplete information
Taxonomic name: Anolis maynardi Garman 1888
Synonyms: Anolis maynardi Nicholson et al., 2005). , Anolis maynardi Schwartz & Henderson, 1991
Common names: Little Cayman green anole (English), Maynard's anole (English)
Organism type: reptile
Little is known about the biology of Maynard's anole (Anolis maynardi). Most easily identified from its long, slender head, it has been introduced to Cayman Brac from Little Cayman, possibly through commodity transport routes; here it has the potential to compete with the endemic Cayman Brac brown anole, Norops sagrei luteosignifer.
Anolis maynardi is a moderate sized anole, with a snout to vent length of 76 mm and a total length of 216 mm. It has a long pincer shaped snout, a pale green throat fan and prominent toe pads. Colouration is capable of changing through various shades of ochre and green to pale blue, gray and occasionally tan. There is a prominent light stripe that extends along the margin of the upper jaw to the insertion of the arm. The belly is pale green to gray. Generally, the body lacks any pattern, except when the lizard is excited or stressed where it can become an ochre colour and develop pale blue longitudinal lines that extend from the head onto the body.
Males are larger tan females with a throat-like fan, a more pronounced pncer-like snout and slightly larger post-anal scales. The long, narrowly constructed throat fan consists of pale yellowish-green skin with large green scales.
The long slender head is probably the most distinctive feature of A. maynardi and can make up as much as 40 % of the toatal snout to vent length.
Nothing is known about the biology of A. maynardi but the forceps-shaped snout suggests a unique feeding adaptation. (From Seidl & Franz, 1994)
planted forests, urban areas
Anolis maynardi has the potential to compete with similar lizard species such as the Cayman Brac brown anole, Norops sagrei luteosignifer (Burton, pers. comm.; in Varnham, 2005).
Anolis maynardi belongs to the Anolis carolinensis subgroup, a clade of nine canopy dwelling species distributed across the northern Caribbean (Seidl & Franz, 1994; Glor et al., 2005). The results of genetic analysis suggest that all non-Cuban members of this group have originated from overwater dispersal and subsequent geographic isolation of Cuban source populations (Glor et al., 2005).
Native range: Little Cayman (Seidel & Franz, 1994).
Known introduced range: Cayman Brac (Seidel & Franz, 1994).
Introduction pathways to new locations
Ignorant possession: Anolis maynardi is thought to have been introduced to Cayman Brac through commodities shipped from Little Cayman (Seidl & Franz, 1994).
Seafreight (container/bulk): Anolis maynardi is thought to have been introduced to Cayman Brac through commodities shipped from Little Cayman (Seidl & Franz, 1994).
