| The Suriname Toad, Pipa pipa (Linnaeus, 1758) is an Amazonian frog that also occurs on Trinidad. These specimen are from southwest Trinidad. It can reach 200 mm in total length. Eggs are laid by the female, fertilized by the male and placed on the female's back by the male. The female's skin then swells and encapsulates the eggs where they undergo development. Food is captured by suction feeding. The long fingers end in sensory organs which detect prey in the water. |

| The Tongueless Frogs occur in South America and Africa, and one African species has been introduced into California. They are highly aquatic with heavily webbed digits on the feet and free fingers with sensory tips. The eyelids are often missing, the eyes are small, and as the common name suggests they lack a tongue. Small species are about 45 mm, the largest species is about 200 mm. There are four living genera with about 30 species. The fossil record contains their remains from the lower Cretaceous of Israel. The South American genus Pipa has a complex courtship and parental care that involves placing the eggs on the female’s back and having the skin swell around them for protection. The eggs develop directly into miniature adults. |
