Using cone beam CT ‐scans to reveal headfirst ingestion and possible prey manipulation tactics in sawsharks

Research output: Contribution to journalArticle

Abstract

Prey manipulation through headfirst ingestion is a common foraging tactic in predatory taxa. Sawsharks possesses a toothed rostrum that is thought to assist in prey capture, but the process from prey contact to ingestion is unknown. Here we provide evidence of headfirst ingestion and possible prey orientation in situ through the use of cone beam CT scans in the common sawshark (Pristiophorus cirratus). CT scans provide an efficient method for assessing ingestion and proposing plausible behavioural tactics for food manipulation in a species difficult to observe in the wild or maintain in captivity.
