Venom in snakes evolved independently multiple times, through convergent evolution.

Snake venom is categorized into different types based on their primary effects, often haemotoxic (damaging blood) or neurotoxic (affecting the nervous system).

Most reptiles and amphibians are carnivores, though some are omnivorous or herbivorous.

How an organism obtains its food.

The maximum opening of a predator's mouth, limiting the size of prey it can consume.

The ability of a skull to move. It allows some animals to open their mouth wider and swallow larger prey.

Herbivorous animals have evolved adaptations like longer guts and special digestive structures to process plant matter.

Proteins in herps' digestive systems play a key role in breaking down and absorbing nutrients from food.

Many factors including size, habitat, diet availability, activity time, and others influences what an organism eats and how it obtains food.

Helodermatid venom glands are located in the lower jaw.

Different ways reptiles and amphibians catch and eat food, varied by environment, prey type, and their physical structure.

A feeding method where an animal expands its mouth cavity to suck in water and prey.

Tadpoles use a raised and lowered buccal floor to filter food from the water ,using gill slits and mucus.

Feeding in air and water have major differences, often in response to how the environment makes it harder or easier to catch prey.

A slow, non-projectile feeding method; the mouth does not open and close quickly with a lot of movement, the mouth stays relatively fixed while food is crushed or taken.

A feeding method using a specialized, rapidly projected tongue to catch prey.

A feeding method with flexible skull joints, allowing more efficient prey capture by a variety of ways the mouth can open to grab prey.

Snakes use a highly kinetic skull to eat large prey with their powerful mouths. Their skulls are designed to eat bigger prey since they are much smaller in the head compared to their body.

A method used by burrowing snakes with modified skulls

Snakes have diverse methods for capturing prey; some constrict, others use teeth, some use venom

The process of using venom by venomous snakes in prey capture.

An important part of the feeding apparatus involved in tongue projection.

The joins in the skull of reptiles that increase feeding efficiency.

A characteristic feature of chameleon feeding

Venom in snakes evolved independently multiple times, a process called convergent evolution, meaning different groups independently arrived at similar solutions.

An organism's diet refers to what it eats, while its foraging mode refers to how it obtains prey.

Various factors influence an organism's diet and foraging mode, including size, habitat, geography, cranial kinesis, digestive proteins, resource availability, activity time, age, behavior, and history.

The maximum opening of an animal's mouth (gape size) limits the size of prey it can consume. Larger prey may be too big to fit in the mouth.

Nine venom proteins are shared by the venom clade, which includes snakes, helodermatids, and other venomous lizards.

Different feeding modes in herps are due to factors like environment (water vs. air), prey characteristics, and the predator's morphology (body structure and adaptations).

Tadpoles use filter feeding, raising and lowering their buccal floor to trap food particles from the water with gill slits and mucus.

A feeding method where the skull is relatively immobile, relying on crushing or gripping prey.

Chameleons project their tongue twice their body length, using specialized muscles and the hyoid apparatus, with binocular vision for accurate aiming.

A feeding method with a highly mobile skull, allowing for greater flexibility in capturing and manipulating prey.

Snakes have evolved highly mobile skulls, using extra joints and specialized muscles to swallow prey much larger than their heads.

Snakes have modifications like reduced bone fusion, increased connective tissue, and independent jaw movements to allow for large prey ingestion.

Burrowing snakes have rigid skulls with modified joints for digging, using lower teeth to rake prey.

Snakes have various methods of catching prey, including constriction, using teeth, and envenomation.

The skull joints in reptiles that increase feeding efficiency by allowing for more flexibility in the mouth opening.
