Common frog (Rana temporaria) tadpole. A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian.Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial.
The Surinam toad catches prey by entraining large volumes of water for ingestion and by limiting fish escape with its fingers. It uses bidirectional suction, a process the frog initiates by depressing its hyoid and retracting its clavicle. The amount of entrained water the frog can ingest is related to its ability to actively increase its body ...
Limnonectes larvaepartus is a species of fanged frog in the family Dicroglossidae endemic to northern and western Sulawesi, Indonesia. [2] It is unique in that it has internal fertilization and gives live birth to tadpoles. [1] Other frog species that have live birth produce froglets.
These frogs are particularly cannibalistic; the stomach contents of feral clawed frogs in California have revealed large amounts of the frog's larvae. [14] Clawed frog larvae are filter feeders and collect nutrients from plankton, allowing adult frogs that consume the tadpoles to have access to these nutrients. This allows clawed frogs to ...
Gosner stage is a generalized system of describing stages of embryonal and larval development in anurans (frogs and toads). The Gosner system includes 46 numbered stages, from fertilized embryo (stage 1) to the completion of metamorphosis (stage 46). It was introduced by Kenneth Gosner in 1960. [2]
Hoplobatrachus tigerinus, commonly known as the Indian bullfrog, is a large species of fork-tongued frog found in South and Southeast Asia. A relatively large frog, it is normally green in color, although physiological traits vary between populations. Sexual dimorphism exists between males and females.
The pickerel frog's poisonous secretions cannot stop all creatures; green frogs, bull frogs, northern water snakes, eastern ribbon snakes, and common garter snakes are their usual predators. [22] When threatened, pickerel frogs will jump into the water and dive to the bottom to escape predators like birds and snakes.
