Hello Sunshinesky,
That's an interesting project. I wish mine were that engaging
I managed to find the following referenced quote:*
(vide infra)
"Adult amphibians are carnivorous, preying heavily on invertebrates. Cannibalism is noted in some larval species, and Sirens are documented as feeding on plants more than occasionally. Larger species, such as Cryptobranchids, Amphiumids, and Dicamptodontids are known to also consume fish, rodents, frogs, and even snakes. The type of prey consumed is thought to be related to the abundance of that particular prey, and may be affected by seasonal changes. Most amphibians change their preferred prey as they develop from larvae to terrestrial adolescent. This is usually a reflection of their changing physiology, i.e. larger teeth, increased gape, or increased motility.
Caudates show a number of "hunting" methods. Some are simply opportunistic feeders, waiting for small prey items to come into reach, while others may actively search for food items. More correctly, most caudates use both methods, depending on the circumstances. Once a food item is located, a short chase may ensue, however, most species will choose not to expend the energy in an active chase. In captivity, when a terrestrial or aquatic salamander gets a whiff of food items, they usually emerge from hiding places and begin searching for the source of the smell. In the wild, terrestrial and aquatic salamanders may use the same cues to begin searching for food.
Caudates mainly use eye sight for hunting, with the exception of the blind salamanders, cave salamanders, and those with reduced eye sight. Caudates are also capable of hunting by scent, as is a common practice in most species. Aquatics and semi-aquatics possess a lateral line system that enables them to detect surface vibrations with exceptional accuracy. The response to potential food is very strong in healthy amphibians, which can been seen clearly in captivity. Many types of caudates become accustomed to regular feedings in captivity, and can be persuaded to accept frozen foods, as well as live foods. Some individuals become very excited during feeding time, often snapping at anything moving, including other caudates, fingers, and forceps. In poor light, such as in murky waters or dark caves, caudates may rely more on olfaction food detection (sense of smell). In captivity, some species switch to olfaction detection as their primary function, especially if trained to accept non-living foods."

This relates to caudates in general, but seeing as axolotls are classed under the order Caudata, there will be some similarities.
Goodluck with your project and welcome :happy:
