Dear colleagues, My co-authors and I are pleased to announce the recent publication of our article on Antillean manatees’ tactile communication in the Behaviour: Lucchini, K., Umeed, R., Guimaraes, L., Santos, P., Sommer, I. & Bezerra, B. (2021) The role of touch in captive and semi-captive Antillean manatees (Trichechus manatus manatus). – Behaviour, 1(aop): 1-23. https://doi.org/10.1163/1568539X-bja10069 <https://doi.org/10.1163/1568539X-bja10069> ABSTRACT: Tactile signals have been neglected in aquatic animal studies despite being a major communication modality. We investigated Antillean manatees’ tactile behavioural repertoire and budget in captivity (7-females and 4-males) and semi-captivity (4-males) in Brazil. We detected 17 tactile behaviours (14.03% of the activity budget) with social, self-maintenance, or environmental exploration functions. The observation method influenced the detection of self-maintenance behaviours — focal animal and ad libitum detected more of these behaviours than scan sampling. Age, sex, housing, and centre routines influenced the tactile repertoire. The captive females and semi-captive males tactile patterns differed, suggesting that sex and animal-pool density play a role in tactile patterns. We recommend carefully choosing the observation method when investigating functional categories of manatee tactile behaviours. The monitoring and stimulation of manatee tactile behaviours should integrate rehabilitation and reintroduction practices. Environmental enrichment may stimulate tactile behaviours related to habitat exploration, key behaviours in aiding manatee navigation.
