Virginia rail
The Virginia rail probe with its bill in mud or shallow water, also picking up food by sight. It mainly eat insects and other aquatic invertebrates, like beetles, flies, dragonflies, crayfish, snails and earthworms. It can also eat aquatic animals like frogs, fish and some small snakes, as well as seeds. Animal preys constitute the biggest part of this bird's diet, but vegetation contributes to its diet in the fall and winter.
Pacific electric ray
The Pacific electric ray feeds mainly on bony fishes, including anchovies, herring, hake, mackerel, croakers, rockfishes, surfperches, kelp bass, and flatfishes, but will also take cephalopods and invertebrates given the opportunity. Its jaws are highly distensible, allowing it to swallow surprisingly large prey: one female long has been observed ingesting a silver salmon ("Oncorhynchus kisutch") nearly half her length. During the day, the Pacific electric ray is an ambush predator: when a fish approaches its head, the ray "jumps" forward from its resting place and folds down its disc to envelop it, while delivering strong shocks. Once the fish is subdued, the ray repositions itself to swallow it head-first. The entire process takes about two minutes.
