Megophrys tadpoles feed at the water surface using unusual funnel-shaped mouths. [5] Anatomy of a wood frog tadpole (Lithobates sylvaticus) As a frog tadpole matures it gradually develops its limbs, with the back legs growing first and the front legs second. The tail is absorbed into the body using apoptosis. Lungs develop around the time as ...
A tadpole person [1] [2] [3] or headfooter [4] [5] is a simplistic representation of a human being as a figure without a torso, with arms and legs attached to the head. Tadpole people appear in young children's drawings before they learn to draw torsos and move on to more realistic depictions such as stick figures.
The hind legs were somewhat specialized in that they not only supported weight, but also provided propulsion. The dorsal extension of the pelvis was the ilium , while the broad ventral plate was composed of the pubis in front and the ischium in behind.
The chick was born with four legs instead of tow, a genetic condition known as polymelia. Polymelia is when an embryo develops extra limbs due to genetic mutations or developmental anomalies.
Lakshmi Tatma is an Indian girl born in 2005 in a village in Araria district, Bihar, with four arms and four legs.She was actually one of a pair of ischiopagus conjoined twins, one of which was headless because its head had atrophied and chest had not fully developed in the womb, causing the appearance of one child with four arms and four legs.
The life cycle of all amphibians involves a larval stage that is intermediate between embryo and adult. In most cases this larval stage is a limbless free-living organism that has a tail and is referred to as a tadpole, although in a few cases (e.g., in the Breviceps and Probreviceps genera of frogs) direct development occurs in which the larval stage is confined within the egg.
Quadrupedalism is a form of locomotion where animals have four legs that are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four legs is said to be a quadruped (from Latin quattuor for "four", and pes , pedis for "foot").
Tadpoles require cool streams with smooth-surfaced stones with a minimum diameter of 55 mm (2.2 in). Tadpoles probably spend most of their time attached to such substrates by a large oral sucker . The large, sucker-like mouth parts of the tadpoles are a second distinctive feature of the species, enabling survival in turbulent water unsuitable ...
