Phyllomedusa trinitatis is a species of frog in the subfamily Phyllomedusinae. It is found in Trinidad and Tobago and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, moist savanna, subtropical or tropical moist shrublands, freshwater marshes, heavily degraded former forests, ponds, and canals and ditches. It is threatened by habitat loss. An interesting characteristic of this frog is it has no webbing on the hands and feet. Researchers suggest that the unique toes might be due to both habitats and its predation behavior. A common predator of this frog's tadpole is dragon fly larva. It can produce poisonous secretion for predator defense. Description P. trinitatis is also known as the Trinidadian monkey frog, the leaf-nesting frog, and the Trinidadian leaf frog. P. trinitatis has parotid glands near its eyes. The frog has black and yellow eyes while much of the rest of the body is a bright green. The frog's chest and chin are brown. However, the color of the frog can also differ depending on its local environment and ability to achieve homeostasis in different temperatures. The frog is described to have no webbing on the hands and feet. Additionally, it has smooth skin on the back dotted with small tubercles throughout. Males are described to lack vocal slits. Distribution The frog can be found throughout northern Venezuela specifically in the following states Distrito Federal, Sucre, Vargas, Miranda, Aragua, Carabobo, Yaracuy, Monagas, north of Bolivar and Guárico, and eastern Falcón. Diet Based on such studies, the researchers proposed that P. trinitatis is often stalking its prey due to its above average size and relatively slow movement. They suggest that the toe pad shape of P. trinitatis might be related to its predatory behavior and not just its habitat. P. trinitatis is also known to eat insects such as field crickets. Predators In a study conducted in Trinidad, West Indies, researchers studied predation of Phyllomedusa trinitatis tadpoles by the dragonfly larvae Pantal flavescens, one of the predators of P. trinitatis during its tadpole stage. Researchers studied whether the larvae had a preference towards tadpoles of P. trinitatis or Physalaemus pusulosus as prey, especially as density of each species varied. Their results demonstrated that the relative prey density has no significant bearing on the dragonfly's preference of hunting for P. trinitatis tadpoles over Physalaemus pusulosus Prior to adulthood, phorid flies in Trinidad
