Short Description of your Research or Creative Project (700 characters or less)
Within the Class of Chondrichthyes or cartilaginous fishes is the poorly studied species of the white spotted ratfish, or Hydrolagus colliei. The objective of this project was to study this species’ diet and reproduction by analyzing stomach contents and gonads. We analyzed 8 males and 37 females. Fish were on average 52.48 cm in length with females being 10 cm longer than males. Fish fed on 4 prey groups, with benthic crustaceans being the most common, and females starting to reproduce at 53 cm length. Our data support previous studies suggesting that this species is a benthic feeder with sexual dimorphism, with females being larger than males and reproducing after they are 50 cm in length.
