Cleaning & Homemaking Objectives

  • Analyze data on cleaning behaviors, determining the impact on animal survival.
  • Provide examples of animal homes, including their construction, architecture, and impacts on animal survival.

Many cleaning and homemaking behaviors have a genetic basis.

If you have spent time watching animals, whether they are wild or domesticated, you see the same basic activities throughout the day: sleeping, thermoregulating, foraging or hunting for food, and cleaning.
 
Often cleaning is overlooked despite critical impact on survival.

Some animals get a significant portion of their nutrients by cleaning other species Oxpeckers are African songbirds that eat ticks, blowfly larvae and other parasites off the skin of large mammmals

Cleaner Shrimp, made popular by the movie “Finding Nemo,” get their food from a number of sources, including cleaning fish, removing dead scales, dirt, and parasites.
 
These recently wild caught shrimp move closer to the camera, potentially for food.
These cleaner shrimp have learned to take food form the hand and readily clean under fingernails.
This cleaner shrimp tries to clean a clownfish.  The fish could damage the shrimp, but does not appear to be alarmed.

Songbirds build nests with a variety of plant materials.  Some are genetically programmed to continually collect fresh leaves.  The fresh leaves of many “wild carrot” plants contain chemicals that repel parasites, including mites and ticks.

Cleaning, or “grooming,” can also be critical for flight and thermoregulation.

Birds continually groom their feathers.  This is critical in creating a continuous air foil for flight, a topic introduced in the next module.

Furred aquatic mammals groom to maintain a moisture barrier essential for heat retention.  Certain environmental pollutants, like oil, can be difficult to remove from fur, and can lead to loss of thermoregulation.

Cleaning is not just about reducing pathogen exposure.  From the behaviors in  this mouse video, what is another benefit of cleaning behaviors?
Cleaning reinforces social bonds in many species.  This may go beyond establishing a dominance hierarchy.  Research on primates suggests that lack of touch in the first six months impacts neural development and social development.

Home Making

Animals construct structures for protection from predators and the elements.

Animals use a variety of building materials.

Building materials need to be readily available and offer some degree of protection.  Some animals utilize mud before it hardens into a semi-waterproof structure.

Several stingless bee species use tree resins as structural material.
 
Besides being flexible, resins contain chemicals that repel potential bee parasites.
One of the most interesting examples of individual invertebrate structure building is the caddisfly Dicosmoecus found in Oregon streams.

Hermit crabs do not build their own structures, they adopt abandoned snail shells, or forcibly remove snails if necessary.
 
Terrestrial hermit crabs are wild-caught from tropical beaches and need complex care including: constant high humidity, both fresh and salt water, deep substrate for molting, a varied diet, and plenty of extra shells as they grow in size.
Animal structures vary in complexity.
Simple nest structures include small scrapes in the ground.

Some organisms use available structures with minimal alteration.  
 
These garter snakes over-winter in underground caves in Manitoba, Canada.  This ability to use caves makes them the northern-most reptiles.
Some of the mosts difficult to study animal structures are built underground.
Moles excavate extensive tunnels in the dirt.  They have cylindrical bodies to fit through tunnels, small eyes, and strong forelimbs for digging.

Structures and behaviors for homemaking have a genetic basis.  Prairie dogs dig even when kept in captivity.
Beavers build impressive homes and have a significant impact on surrounding habitats and organisms.  We will have more on beavers in an upcoming laboratory.
The next section introduces the most diverse of Phyla in Kingdom Animalia: the arthropods.
