Celebrando los delfines de Risso este Día de la Tierra

ES: En este Día de la Tierra, celebramos una victoria para el océano con los delfines de Risso.🐬 Hace algunos años, estos delfines quedaban atrapados en grandes cantidades como pesca accidental, resultando heridos o muriendo en las redes de pesca de atún. Afortunadamente, las estrictas regulaciones  promulgadas en 2009 llevaron al desarrollo de prácticas de pesca de atún más seguras para los delfines en Estados Unidos, lo que ayudó a que sus poblaciones se recuperaran.

Hoy, los delfines de Risso son una presencia común en las aguas de la Bahía de Monterey. Se pueden ver con frecuencia por las embarcaciones de observación de ballenas e incluso por los visitantes desde nuestras terrazas.

Actualmente, esta especie está clasificada como de «Preocupación Menor» según la @IUCN, un poderoso recordatorio de que las políticas y la acción pueden generar un cambio real.

Elegir productos del mar sostenibles protege tanto al océano como a las personas que dependen de él para subsistir.

¡Cuéntanos qué es lo que más te gusta de estos delfines maravillosos!

EN: On this Earth Day, we’re celebrating an ocean win with Risso’s dolphins.🐬These dolphins were once lost in large numbers as bycatch, accidentally harmed and killed in tuna fishing nets. Thankfully, strong legal regulations enacted in 2009 led to the development of more dolphin-safe tuna fishing practices in the United States, helping their populations rebound.

Today, Risso’s dolphins are a common sight in the pristine waters of Monterey Bay, often spotted by whale watching boats or even by guests on our back deck.

This species is now listed as a species of “Least Concern” according to the @IUCN–a powerful reminder that policy and action can make real change. Choosing sustainable seafood protects the ocean and people who depend on it.

Tell us what you love about these dolphins!

Gramps

Work continues on the SECAC commission, and the end is in sight with just 2 more illustrations to go! I've just finished grandpa Grampus. Because after the "standard" Risso's dolphin (below, finished in 2022) SECAC also wanted an old male.

Risso's are very interesting in terms of colouration because they change so much throughout their life. They are born rather dark, and bear a colouration pattern akin to many other dolphins, with light grey undersides and a dark cape. Like pilot whales they have a white "anchor" marking on their chest, connected to a white patch on the belly. But as they age this colouration is snowed under by countless rake marks: scars brought on by the teeth of conspecifics. In many dolphin species these scratches quickly regain the same colour as the skin. In Risso's they stay white, likely acting as a sort of score bord for males to broadcast their fitness and fighting prowess.

Still, there's a lot of cool variation. Very old males can turn almost completely white (my illustration is quite conservative) with the underlying colouration also bleaching. Females usually have less scars but there's a broad range going from almost clean to being quite pale indeed with many rakes. Some animals develop white faces (with or without stark black markings surrounding the lips). And in some populations the animals just remain quite dark and seem to gather far less, or smaller rakes overall.

I found a couple of whale toys from when I was a kid, they were in one of those little tubes full of plastic animals. I decided to give them a new paint job :)
