Inflation of Moth Coremata

Description:  This viral video (with added sound effect) shows an entomologist inflating the coremata in a recently deceased male moth. This pheromone-producing organ will normally sit inside the moth but will be used during courtship to attract potential mates. It is inflated with blood or air. This phenomenon could be used as an example of how organisms increase their change of reproduction through internal and external structures.

These are the androconial organs, which male moths use to release pheromones and attract females. In this species of insect, the organ consists of inflatable tubes at the tip of the abdomen.

Mouthbrooding Fish

Description:  Lake Malawi contains a curious species of fish (ciclid) that hold their offspring in their mouth as they grow and develop. The eggs are fertilized and then help in the mouth until the offspring are able to survive on their own. The parents can still feed while they are taking care of the young but they will generally not feed as much. This phenomenon could be used to explore parental care and could be extended to discuss evolution of this interesting adaptation in this lake.

Male Water Bug with Eggs

Description:  Water bugs show parental care for their offspring. The eggs are laid on the back of the male and he guards them for roughly a week before the nymphs emerge. This phenomenon could be used to show how the behavior of parents helps the offspring survive. Offspring of these (and other invertebrates) could also be compared to show inheritance and variation.

Shrew Caravan

Description:  Shrews spend most of their lives underground and therefore have very poor eyesight. They rely primarily on their highly developed senses of smell and hearing. When a mother shrew wants to move all of her offspring from one location to another (particularly above ground) each shrew will hold onto the shrew in front forming a long caravan. This could be used as a phenomenon to introduce animal behaviors, especially those of a parent to ensure the safety of their offspring.
