Eleutherodactylus Beguei Essay
Description:
Eleutherodactylus beguei is a small-sized frog at 15.2 mm. The length and width of the head are proportionate in size, equaling about the same in distance. The snout is slightly pointed and overlaps the lower jaw. Nostrils have an oval shape, do not protrude from the head, and are laterally directed. Canthus rostralis is distinguished as flat from a dorsal viewpoint, but rounded in profile. On the eyelid skin a few small granules are visible. The loreal area is smooth and gradually slopes towards the labial border. They have a rounded tympanum with clear annulus. Equal to that of the third finger’s disc, oval in shaped, and is overlapped by the palatal shelf is the choanae. The tongue’s shape is partially oval and the posterior half is not …show more content…
beguei from other related species, the first characteristics to notice would be the coloring or markings. Two related species of E. beguei are E. feichtingeri and E. varleyi. E. feichtingeri is uniform in color and displays a chevron or diamond shaped pattern (Diaz et al. 2012). For E. varleyi, the perimeter of the snout has a black stripe and is typically reddish brown in color (Diaz et al. 2003). Listening to the advertisement call would allow for quick determination. In E. feichtingeri they have a short metallic advertisement call that can be heard from 50-meters away (Diaz et al. 2012). While, E. beguei’s soft chirps can be barely heard from a 10-meter distance. To further differentiate; observing the development of the vocal sac will provide indications for determining the proper species. E. feichtingeri and E. varleyi from a ventral view of the throat have visible flaps of skin that are used during advertisements. However, E. beguei has a relatively small vocal sac and don’t possess the gular folding. Furthermore, the post-femoral glands of E. varleyi have a tendency to be more swollen and highlighted compared to E. beguei where they can be difficult to locate (Diaz et al.
