Developmental And Functional Analysis Of Scutes In The Armored Catfish Corydoras Aeneus, Emily Volk Jan 2019

Developmental And Functional Analysis Of Scutes In The Armored Catfish Corydoras Aeneus, Emily Volk

Undergraduate Honors Theses

Fish scales are specialized biological structures of current interest in innovative materials design because of the combination of protective function, flexibility, and light weight they offer. This study presents a developmental and functional investigation of a particular fish scale structure, the scutes (bony external plates) of the armored Bronze Corydoras Catfish (Corydoras aeneus). Scutes in this model fish species were analyzed via three complementary approaches. First, scutes were documented throughout fish development via high-quality microscope images. These images were subsequently used to inform fabrication of synthetic models to characterize the relationship between scute overlap and overall bending stiffness of scute ...

Continuing Improvements Of The Sharkduino Animal Tag System, William Laney

Undergraduate Honors Theses

Much about the movement and habits of marine animals is still unknown. This information can be found for terrestrial animals through direct observation or video surveillance; however, these optical methods are not effective in aquatic environments. To circumvent this problem, researchers “tag” aquatic animals with small sensor systems that record data about the animals movements. The researchers then recover the tag and use signal analysis to draw conclusions about the habits of the animal. Unfortunately, commercially available tags are expensive and most can only be used once. We created an inexpensive and reusable tag to be used on sandbar sharks ...
