This National Science Foundation (NSF) Biological Sciences program award of $365,966 to the Woods Hole Oceanographic Institution (WHOI) aims to provide a comprehensive understanding of the evolution and development of shark skin denticles, the tooth-like scales that create a hydrodynamic exterior. The project will investigate how denticle shape has changed over millions of years to optimize drag-reduction during aquatic locomotion. Key goals include determining the genetic and developmental...
This $857,250 National Science Foundation project grant supports research into the evolution of nociception in elasmobranchs through June 2025. The grant funds research at the University Corporation to determine if sharks experience pain by identifying cell types and structures associated with nociception. Researchers will analyze shark genome and transcriptome data to identify pain receptor sequences and profiles in dorsal root ganglia. Immunohistochemistry will label putative nociceptors,...
This Project Grant from the National Science Foundation Division of Environmental Biology, under the Biological Sciences program (CFDA 47.074), provides $961,754 to Rice University from May 1, 2023 to April 30, 2028. The grant supports research investigating modularity in the diversification of the acanthomorph fish skull through three-dimensional geometric morphometrics analysis of micro-computed tomography scan data from over 1,000 fish species. Key products include quantifying the tempo and...
This National Science Foundation (NSF) Project Grant under the Geosciences program (CFDA 47.050) provides $708,199 to the Woods Hole Oceanographic Institution (WHOI) to develop a robust, open-source toolkit for analyzing microfossil fish teeth and shark scales (ichthyoliths) to study fish evolution and ecology. The 5-year project, running from April 1, 2025 to March 31, 2030, will leverage machine learning and digital imaging to create a framework for taxonomic identification and paleoecological...
This National Science Foundation project grant of $139,432 awarded on May 1, 2022 will fund research into the hydrodynamic consequences of spines on zooplankton morphology and function under the Biological Sciences program (CFDA 47.074). Specifically, the award to the University of California, Berkeley supports a collaborative research effort between the university and a small liberal arts undergraduate college to examine the ecological functions of spines in different barnacle nauplii larval...
The National Science Foundation Division of Emerging Frontiers awarded a $431,276 Project Grant to the President and Fellows of Harvard College from August 15, 2021 to July 31, 2024. The grant supports research titled "INTBIO COLLABORATIVE RESEARCH: DEEP TIME, DEVELOPMENT, AND DESIGN: EVOLUTION OF SHARK SKIN TEETH FROM GENOTYPE TO PHENOTYPE TO PROTOTYPE" under the Biological Sciences program (CFDA #47.074). The research aims to advance understanding of how shark skin teeth evolve...
This $690,650 Project Grant awarded by the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) supports the development and testing of a field-ready, cost-effective sound playback system for conducting eco-acoustic and marine larval settlement studies. The system will enable researchers to easily manipulate and introduce sound cues in field experiments to investigate how sound impacts diverse marine fauna, with a focus on coral reef ecosystems. The 2-year effort will build,...

The grant will support research titled "INTBIO COLLABORATIVE RESEARCH: DEEP TIME, DEVELOPMENT, AND DESIGN: EVOLUTION OF SHARK SKIN TEETH FROM GENOTYPE TO PHENOTYPE TO PROTOTYPE." The research aims to advance understanding of the development and evolution of shark skin teeth...
This $677,674 federal Project Grant award from the National Science Foundation's Biological Sciences program (CFDA 47.074) will fund the development and testing of a bioinspired, long-term telemetry attachment device for monitoring critically endangered marine mammals. The principal investigator's research team at the New Jersey Institute of Technology will collaborate with various universities, industry partners, and federal agencies including NOAA Fisheries, the Alaskan Eskimo Whaling...
This Project Grant award, valued at $231,912, was provided by the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) to the University of Washington (UW) to study the hydrodynamic consequences of spines on zooplankton, particularly barnacle nauplii larvae. The key objectives of this research project are to: (1) determine the functional consequences of the presence, location, and morphology of spines on hydrodynamic forces and torques; (2) examine the impacts of spines...

This National Science Foundation (NSF) Project Grant award under the Biological Sciences program (CFDA 47.074) provides $409,878 to CAL Poly Humboldt Sponsored Programs Foundation (HSU Foundation) to conduct collaborative research on the relationship between the inner ear morphology and habitat of sharks, rays, and their relatives.

The key products and services to be delivered through this 3-year grant include:

  • Using computed tomography (CT) and magnetic resonance imaging (MRI) to document the skeletal labyrinth morphology of inner ears across all living shark and ray families
  • Assessing the relationship between inner ear shape and locomotor ecology/habitat of these marine organisms
  • Developing 3D anatomical models of shark and ray inner ears for educational use at K-12 and college levels, as well as for public displays
  • Contributing to resolving phylogenetic conflicts among chondrichthyan groups by incorporating inner ear morphological data into evolutionary analyses
  • Training and supporting two graduate students and undergraduates to present research at conferences and contribute to published papers

The findings from this research project aim to advance the understanding of ecomorphological relationships in non-tetrapod vertebrates and provide new insights into the evolution and ecology of cartilaginous fishes.
