#Grampus griseus

Trick or treat!!

Treat! Thanks for being the first to come into my inbox for this event :D I wanted to make a ceta doodle and for inspiration chose a random photo from my large reference collection. It turned out to be a picture of a Risso's dolphin who'd lost part of their dorsal fin to a killer whale. It's a photo that has always intrigued me - as do others of a similar nature. What luck they had to escape with their life. And I wonder if they ever think back to that moment? That haunting feeling was something I wanted to capture. It turned into a biiiittt more than just a quick doodle lol but I really love the end result.

The one who got away

Her teeth marked my fin And took a part away A small offer for my life She haunts me anyway

Excerpt from this story from the Smithsonian Magazine:

Risso’s dolphins are deep-diving aquatic mammals that typically swim in groups of 10 to 30 individuals. But late last month, more than 1,500 of them congregated off the coast of central California, creating an unusual and awe-inspiring spectacle for human observers.

Staff with Monterey Bay Whale Watch, a whale-watching tour operator, captured drone footage of the “super pod” of Risso’s dolphins (Grampus griseus) frolicking in Carmel Bay on January 24. The company’s 20-foot, inflatable scouting boat was cruising along the coast south of Monterey, surveying migrating gray whales, when they came across the Risso’s dolphins.

At first, the small crew thought they were seeing a few hundred dolphins. But when they put up a drone, they realized they were actually looking at more than 1,500 of the cetaceans.

“It was just an amazing sight,” says Evan Brodsky, who was captaining the boat that day and captured the drone footage, to��KSBW’s Zoe Hunt. “Just little white dots everywhere, and every single one of those white dots was a dolphin.”

Risso's Dolphin Grampu griseus Family: Delphinidae Genus: Grampus Status and Conservation: Least Concern Working on this one was very relaxing. Dolphins take me not so much time and still, the result is nice, So I usually work two every week I'm working on this family. Still amazed at how little I know about this bug family and how interesting its members are. If you want to know more about them, you can join my club here ____________________________ That will be it for this week. If you like the content, leave me some love. Reblogs are also loved. This blog is becoming the most complete source of mammals. Adios!

Risso’s dolphin - Grampus griseus

Length: 13 feet

This gray dolphin has a large, rounded head. As it grows older, its skin gradually becomes white. It has no teeth in its upper jaw and sometimes no teeth at all. It swims the seas leisurely in groups of up to several dozen.

*[White scars]

Adults look white because of countless scars on their skin. All dolphins and whales are injured at some point, but their scars usually fade with time. This species’ injuries leave permanent white scars that gradually turn their entire body white as they get older.

Risso’s Dolphins

Notes: This is only the Second time that Risso’s have been documented in the Salish Sea! The current rare visitors (as of 01/29/2022) are a Fin Whale near Seattle (only the third time Fin whales have been in the Salish sea), a pod of Risso’s (pictured above) near Salt Spring Island, and the A42s of the Northern Resident Killer Whale Population in the Gulf Islands!

Risso's Dolphins (grampus griseus)

taken in the Pacific Ocean off the coast of Catalina Island

status: least concern

We came across this fun pod of Rissos as we were heading in for a break at Two Harbors! There were quite a few younger members of the pod who weren't quite as covered in scarring as the previous pod I'd seen. The individual with its head up though shows how scarred these guys can get. In contrast the one which you can only see the dorsal fin of is far less scarred and shows the color they are prior to scarring really well - often times this means its a younger individual.

Risso’s Dolphin | Grampus griseus

“Risso's dolphins can dive to at least 1,000 feet and hold their breath for 30 minutes, but they usually make shorter dives of just a few minutes. They feed on fish (e.g., anchovies), krill, and cephalopods (e.g., squid, octopus, and cuttlefish) mainly at night, when their prey is closer to the surface. Most of their diet consists of squid, and they have been known to move into continental shelf waters when following their preferred prey.” (Source)

SEALIFE illustrations pt1: BLACKFISH Last summer, I was commissioned by SEALIFE dolphin watching to create some illustrations for their new educational building. They opted for full realism, which made me very happy - it’s been a while since I could go all out on the nitty gritty details of pretty cetaceans. Over the next few days I’ll upload them all so you can finally see these beautiful boys and girls too. 

★ Killer whale (Orcinus orca) Although little known from the actual Mediterranean, around the strait of Gibraltar and further afield sightings are more common. They have funky bulbous melons and stout dorsal fins around there, and the warm Portugal sun can make them look almost brownish at times.

★ Short-finned pilot whale (Globicephala macrorhynchus) Oof, this has to be one of my favourites. I find short-fins especially handsome to begin with, with their sleek bodies, big backswept dorsal fins and expressive eyes. Their subtle markings are beautiful and complex too - and I’m just so pleased with how this one turned out. This is a male, the females have more modest dorsal fins. 

★ Risso’s dolphin (Grampus griseus) Another personal favourite. Having painted Risso’s before, I was a bit daunted at the prospect of painting all those scars in detail this time. But it turns out drawing sucker scars and rake marks is pretty fun and I’m stoked with the result. Like pilot whales, Risso’s eat mostly squid. However, their skin does not repigment after scar tissue has formed, so the result of every skirmish with both colleagues and prey are permanently etched on their bodies.

A Risso’s dolphin caught up in fishing line. Dolphin numbers in the Indian Ocean may have dropped by more than 80% in recent decades, with an estimated 4 million small cetaceans caught as “by-catch” in commercial tuna fishing nets since 1950, according to a study

Jumping into the weekend like... a Risso's dolphin in Monterey Bay! Delightful photo from Moss Landing by local photographer Joe Platko (IG: @hiimjoe88)

Yes, we know—how is it a dolphin if it doesn't have that classic "nose"?! The long rostrums of bottlenose and common dolphins are certainly recognizable, but many dolphins—like white-sided and Risso's—have shorter snouts, resembling porpoises. The big tell that you're looking at a dolphin and not a porpoise? The dorsal fin of a dolphin has a curved trailing edge that, while porpoises have triangular dorsal fins without much—if-any—curvature. Another clue? Dolphins have conical teeth, white porpoises have teeth that look like little spatulas!

Quite a rare treat yesterday- Risso's Dolphins!

Captain Tom and crew sighted a pod of about 20 Risso's on the first trip of the day outside of the Dana Point harbor. These squid specialists have not been seen as often locally in recent years, it is always a thrill to see different marine species.Yesterday's sightings also included 5 Minke Whales, 1 Humpback Whale (Blackie) and 800 Common Dolphin- quite a grand slam of wildlife!
