In grasshoppers, incomplete metamorphosis consists of three distinct stages: egg, nymph, and adult.

The Giant mole rat (Tachyoryctes macrocephalus), also known as the giant root rat, is endemic to Ethiopia and lives in the high altitude Afro-alpine grasslands of the Bale Mountains.

Kinesis is an undirected, random movement where an animal changes its speed of activity based on stimulus intensity rather than stimulus direction.

Anopheles mosquitoes serve as vectors that transfer malarial parasites (Plasmodium) from one person to another.

Following cleavage, cell divisions and rearrangements lead to the formation of a hollow structure called a blastula (or blastocyst).

The magnum is the longest section of the avian oviduct and functions in secreting and depositing almost all of the albumen around the yolk.

The blister beetle (Epicauta) eats up masses of locust eggs, serving as a natural biological control agent against locust populations.

Punishers are environmental responses that decrease the likelihood of a behavior occurring again by weakening that behavior.

The isthmus is the relatively short section of the oviduct where glands produce sulfur-containing amino acids required to form the inner and outer shell membranes.

Blister beetles produce cantharidan, a powerful protein blocker that prevents viral replication and reacts with the genetic material of hostile cancer cells.
