You wouldn't ride dirt bikes through a kiwi sanctuary, so why is it okay to race boats in Hector's dolphin habitat?

Next month, the SailGP competition will be taking place in Lyttelton Harbour, near Christchurch in New Zealand. This competition will involve boats racing at speeds of 100 km/h or faster, through areas where endangered Hector's dolphins are known to inhabit. At these speeds, if a dolphin is spotted ahead of the boat, it will be too late to change their course, and it's almost certain that a strike from one of these boats would kill a dolphin. What makes this even worse is that the race will be happening during the breeding season, when Hector's dolphins move closer to the coastline to birth and nurse their calves, making them even more vulnerable.

These tiny dolphins need our protection now more than ever - they already face threats from fisheries bycatch and toxoplasmosis. I am ashamed of the lack of responsibility my country has taken to ensure the continued survival of the Hector's and Maui's dolphins. This fiasco is just the latest in a series of failures to prioritize the welfare and safety of endangered marine life in New Zealand.

We wouldn't let people ride dirt bikes through a kiwi sanctuary. There would be public outcry if people were driving through penguin colonies. We should show that same level of care and concern for our endangered marine mammals. The wealth and influence of New Zealand's sailing community should not make them immune to these standards.

Another northern right whale is dead, this time a proven breeding female who had just given birth to her sixth calf—one of only 70 potentially reproductive females left in existence.

Without its mother, that little one is expected to become the fifth of these critically endangered whales to die in 2024 alone. With a population as small as this, each loss is devastating.

Please urge your representatives to support legislation regulating boat traffic and fishing activities, which are the main threats against these whales.

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!

To support climate action we must protect the whales.

I’m always asked which area of marine I would like to go into for a career,

the answer is always and will always be cetacean behaviour and conservation.

Why?

Cetaceans, particularly the great whales, bring stability to our ever-changing climate.

When whales dive into the depths of the ocean, they then return to the surface water to breathe. Upon returning to the surface, whales release enormous faecal plumes, containing limiting but essential nutrients that stimulate the growth of phytoplankton.

Phytoplankton, an organism forming the basis of all, marine food, is essential for life on Earth. These microscopic organisms act as carbon fixers by sequestration carbon from the atmosphere to be utilised in their bodily structures. Reducing the number of phytoplankton is undeniably going to cause higher quantities of greenhouse gas emissions remaining in the atmosphere and as a result warming the climate.

Whales' defecation acts as a natural fertiliser in our oceans and is essential in the growth of phytoplankton thus combatting climate change.

Without whales, phytoplankton numbers will reduce meaning greenhouse gas emissions are no longer removed from the atmosphere through these carbon fixers. This creates an increasingly warmer climate, one uninhabitable and one that will impact ALL life on Earth.

Our future lies in our oceans, particularly baleen whales who store astonishing amounts of carbon throughout their 100-year lives. Even when these individuals die, the carbon remains locked in the dead body for centuries to come.

Whales face many threats.

Whaling and climate change are impacting their populations the most.

We must protect whale populations from the threats we have caused

Not only will it benefit whales, but it will benefit all marine life, terrestrial life and even us, humans.

Whales are not only incredible species but a natural solution to climate change one that deserves to be protected.

In an effort to get myself used to this site and encourage me to use it more, I'm jumping on the Wet Beast Wednesday trend and posting facts about a different aquatic animal every week.

Starting off cute and sad, I’m going with the vaquita (Phocoena sinus). This dog-sized porpoise is the world’s smallest cetacean and it only lives in one place in the world: the northern end of the gulf of California near Baja. Sadly, they are critically endangered, with an estimated population of less than ten left in the world as of February 2022, making it the most endangered marine mammal (I couldn't find estimates for this year). This is primarily due to them getting tangled in gill nets from illegal fish poaching in their habitat. A study in 2022 indicated that the species may be able to repopulate but they would likely have genetic problems from a severe population bottleneck. Attempts to establish a captive breeding population were unsuccessful. Conservation efforts have generally been ineffective due to the sheer scale of illegal fishing activities, though there is cooperation between the USA and Mexico as well as international pressure on Mexico to crack down on the illegal fishing and protect the vaquitas

Not a lot is known about vaquitas due to how rare they are and because they were only identified as a species in the 50s through bones and scientists didn’t even see an intact specimen until 1985. What we do know is that they are very small, the the larger females reaching a maximum size of about 150 cm (4.9 ft). Males are believed to compete for mates and females usually reproduce once every two years. They are usually found alone or in small groups. Vaquitas have distinctive dark markings around the eyes and mouth.

The vaquita is on the edge of extinction and if rapid, extensive conservation efforts aren’t enacted, they will be gone forever. The vaquita could be a good symbol of why conservation is important and why conservation efforts need to be extensive and properly enforced for them to be effective. I could see them becoming a symbol for endangered species lie polar bears and pandas have become. They are in need of critical help but very well could survive with that help and they are adorable, which is always good for public awareness

Thank you for sharing this! This is another one of those situations where we are just now seeing the noticeable, dramatic payoff of years and years of quiet, unnoticed environmental work.

"Experts say years of conservation efforts have resulted in some of the healthiest waters in generations, with booming fish populations, clearer ocean waves and more chances to interact with our urban aquarium."

This quote also really got me:

"'It never gets old, it’s always thrilling,' said Celia Ackerman, a naturalist with American Princess Cruises who captured the images. As a child growing up in Brooklyn, Ackerman couldn’t wait to move out of the city so she could study marine animals. 'I would have never imagined I could enjoy them here right in my backyard.'"

Common dolphin surface sequence

Even the simplest thing can be a surprisingly subject. Dolphins repeat this sequence continuously while they travel, and it's just incredibly cool to see them.

Hiya! Would you be willing to explain why keeping captive right whales is completely nonviable, as you mentioned? I’m fascinated, but the adhd simply will not let me parse scientific papers.

That's a fantastic question! While it would be wonderful if captive breeding were a viable option for this critically endangered species, it just isn't possible under any realistic conditions.

For starters, their size. Orcas are the largest mammals successfully held in captivity, and we all know how difficult (and controversial) that is, with only a very small handful of facilities ever pulling it off with any semblance of success. Tilikum, the largest captive orca (although I believe that record has since been overtaken by a male in China), was 22.5 feet (6.9 meters) long and weighed 12,500 pounds (5,700 kg). Most other orcas in human care, particularly the females, are considerably smaller. Compare that to a northern right whale. Even the smallest adults are over 40 feet long—double Tilikum's length—and weigh 88,000 pounds (40,000 kg)—seven times his weight—while the biggest specimens on record reached up to 61 feet (18.5 m) and an incredible 234,000 pounds (106,000 kg).

A tank for an animal that size would be far beyond anything we have the ability to engineer and maintain. Think of how deep it would have to be for the whale to even turn around! The water pressure would be astronomical, wreaking havoc on the building materials even if it were possible to build the structure. And remember—someone has to dive to clean it! Our theoretical right whale habitat would have to be a sea pen, but even the 100-acre facilities proposed with orcas in mind are nowhere near deep enough. While right whales are considered to inhabit "coastal" waters, they do not live right up by the shoreline, like certain orca ecotypes and other small delphinids. They are a pelagic species, designed to live out in the open water column, as are all baleen whales. So, the pen would have to be a floating habitat miles out into the open water (think of an offshore oil rig), with netting sturdy enough to not be destroyed by a 50 ton whale and long enough to extend hundreds of feet to the ocean floor. We're talking probably thousands of square miles of netting, that would have to be routinely inspected for safety and upkeep. So, you would probably need a submersible, since no human can dive that deep. On top of that, it would be difficult to find such a larger stretch of ocean in their habitat without shipping lanes, underwater noise, or pollution. And let's just forget about the logistics of staffing that place—or worse, funding.

Additionally, we wouldn't be able to feed them by tossing fish into their mouth like with dolphins. Northern right whales feed on tiny crustaceans and zooplankton, cruising along and filtering the creatures from the water with their baleen. Assuming our right whale keepers were somehow able to acquire the insane amount of food the whale requires (potentially over 5000 pounds of zooplankton a day), it would need to be scattered throughout the massive habitat to facilitate feeding. I imagine this would probably look something like the way Georgia Aquarium feeds their whale sharks from a little boat, although on a much larger scale. And since the food obviously can't be kept alive, we would need to develop someway of delivering the daily vitamins that are lost in the freezing process—and to keep hundreds of tons of krill frozen on a floating kitchen in the middle of the ocean.

Of course, the ultimate goal of this project would be to breed northern right whales... that means we need to take everything we just talked about and double it, at a bare minimum. For the breeding program to be successful, it would need a whole lot more than just two whales. And unfortunately, even if we lived in world with magical floating thousand-acre sea pens, unlimited krill, and endless money... we still don't know if it would even work. Right whale breeding habits are poorly understood, with the whales mating in cold northern waters before migrating 1,000 miles south to calve. Despite our best theoretical efforts, these migratory patterns could very well be necessary for successful reproduction.

Thank you again for the ask! This was actually a lot of fun to think about! If you want to read about JJ, the only baleen whale ever successfully housed in (temporary) human care, you can find an article and pictures here.

I really enjoyed illustrating cetaceans. They are kind of easy to do, they don't take many hours (like just 2), and the results are stunning. In this case, I added the lights of the high contrast from the humidity of the skin of the animal and I think make the illustration look more realistic. On the other hand, these genera of dolphins are simply beautiful. I didn't know the existence of many of them and discovering them really surprise me.

Heaviside's Dolphin This dolphin can be found in the coastal waters of South Africa. As the other members of the genera are small size dolphins with the same colors as their relatives but with a specific pattern.

They are very energetic and can be seen closer to boats. They use echolocation (a way of hunting used primordially by bats) to hunt, which means they use sound to find their prey. Prey are mostly fishes and mollusks. They are not expert divers with dives commonly going down to 50 meters. However, some register dives were down to 147 meters. Dives length is no more than 2 minutes.

As for predators, the only known is the Orca. __________________________________________________ Credits: Heaviside's dolphin _________________________________________________ Store Instagram Thank you guys for your love and support.
