The most exhilarating wildlife experience I’ve spectated. My mind is beyond blown. Strongly considering adding Jaguar to the list of diving mammals I’d like to study after seeing this apnoea 🤔🤔🤔 🐆🐆🐆 @cristinlambert

The gen 2 instrument is now commercially available. This non-trivial case study should pave the way for similar studies in other taxa and species. 🧵.

Lastly, observed changes in the swim speed of seals that were consistent with predictions from CFD estimates of drag, showing the validity of CFD as a tool to predict AND reduce impact from tags.🧵.

We then employed CFD modelling to design a new, low drag Gen 2 device that resulted in a lower additional drag of 8.6%.We show significant differences in behaviour when carrying a Gen 2 compared to Gen 1 tag, demonstrating that the redesign successfully reduced impact.🧵.

We experimentally demonstrate the impact a the widely used Sea Mammal Research Unit (SMRU) Instrumentation Group GPS/GSM (Gen 1) tag has the behaviour of a phocid seal. 🧵.

Maitheas bainne cíoch an róin go ndéanfaidh sé duit = ‘May it do you as much good as seal's milk', is a blessing, for it was believed that a young seal puts on a layer of fat each time it nurses on its mother.

For #InternationalSealDay here’s some of my favourite words and phrases for seals in Irish (os geailge) ☘️ 🦭 🧵 @_SMRU_ . Rón = seal.Bainirseach = female seal.Éan róin = seal pup.Gormánach = pup after it’s moulted it’s lanugo.Oisín = juvenile seal
