Description & Behavior

Cookiecutter sharks, Isistius brasiliensis (Quoy and Gaimard, 1824), aka cookie-cutter shark, smalltooth cookiecutter shark or cigar shark, are small, deepwater sharks named for the cookie-shaped wounds they leave on larger fish and marine mammals.

Cookiecutter sharks live in the warm, deep waters of equatorial oceans, primarily in coastal waters near islands. They inhabit deep waters below 1,000 m during the day and migrate into surface waters at night at around 300 m. They have been found in depths up to 3,500 m.

Feeding Behavior (Ecology)

Cookiecutter sharks, appear to blend with the light from above when viewed from below due to the shark’s ventral photophores that disguise the shark’s outline. The primary prey of the cookiecutter shark are squid, small fish (likebristlemouths), and crustaceans.

This shark also feeds on larger pelagic animals such as wahoo, tuna, billfishes, and marine mammals. It is a facultative ectoparasite, which means that it feeds on the flesh of other species causing them harm but not death and it is not dependent on these species for survival.

A dark patch on the ventral surface of the cookiecutter shark resembles a smaller fish when viewed from below and is thought to lure larger fish and marine mammals that may be swimming beneath it. When this sneaky predator attacks its prey, it grabs hold of the flesh with its lips and bites using its small, sharp upper teeth to grip the prey while it cuts the flesh with the large, serrated lower teeth. The cookiecutter shark then spins its body to remove a “cookie-shaped” plug of flesh which it swallows before releasing its prey.

Unlike other shark species that lose teeth individually, the teeth of the cookiecutter shark are shed as a single unit. The bottom teeth are swallowed, possibly to help maintain calcium levels in the body.

Life History

Cookiecutter sharks are ovoviviparous. Hatching takes places between 12-22 months with 6-12 pups per litter. When the young emerge, they are fully developed and able to hunt for food by themselves. Males mature at 36 cm and can grow to a size of 42cm. Females mature at 39 cm and can reach up to 56 cm.

Ovoviviparous: eggs are retained within the body of the female in a brood chamber where the embryo develops, receiving nourishment from a yolk sac. This is the method of reproduction for the “live-bearing” fishes where pups hatch from egg capsules inside the mother’s uterus and are born soon afterward. Also known as aplacental viviparous.

A letter to the special little snowflake who hacked Miami Seaqurium. 

Hello! I would appreciate it if you DMed me or sent me an ask. 


You are a beautiful creature who deserves hugs. Thank you for telling the truth for miami Seaqurium, since they choose not to do that themselves. 

What you did brought me and others happiness, but better yet Miami Seaqurium strife. 


Thank you!

One question: how can you openly endorse this cruelty and promote it to your millions of fans?

:( good job I don’t actually like any if these and any celebrities I do like tend to be against captivity

THE OCEAN CLEANUP PROJECT

Guys, this is huge. We have the potential to clean up one of the biggest messes humanity has made: The plastic in the ocean.

THE PROBLEM

Through littering and other such forms of carelessness, we have introduced millions of tons of plastic into the oceans. This plastic is trapped in the five major currents running through the world’s major oceans, called gyres. There is currently six times more plastic in the water than zooplankton, which is one of the most basic elements of the worldwide food chain. Plastic in the oceans leads to ecological, economical, and health issues for everyone, including people.

THE SOLUTION

Really, the solution is to cut the problem off at its source and find ways to stop introducing plastic and other garbage into the oceans. But, as for all the trash that is already there, a 19-year-old man named Boyan Slat has come up with an idea: Get the oceans to clean themselves. This idea has three basic principles:

1) Passive collection

  • Why move through the oceans, if the oceans can move through you? Attaching an array of floating barriers and platforms to the sea bed enables us to concentrate the plastic before extracting it from the ocean —a collection process 100% driven by the natural winds and currents.”

2) Capturing plastics, not sea life

  • "Instead of nets, we make use of solid floating barriers, making entanglement of wildlife impossible. Virtually all of the current flows underneath these booms, taking away all (neutrally buoyant) organisms, and preventing by-catch, while the lighter-than-water plastic collects in front of the floating barrier."

3) Highly scalable

  • "The scalable array of moorings and booms is designed for large-magnitude deployment, covering millions of square kilometers.
  • Thanks to its projected high capture and field efficiency, a single gyre can be covered in just 5 years (or longer, depending on the chosen deployment strategy).”

IS THIS EVEN POSSIBLE?

Great news: Yes! In June of 2014, Slat and his team of 100 professionals and volunteers announced that this can happen. You can download the full report here, or the summary here. You can also watch Slat’s recent talk to find out more about how the project really works right here.

WHAT CAN I DO?

Slat and his team are currently running a crowdsourcing campaign. They need to raise $2 million US dollars to move from the feasibility phase to the implementation phase. That sounds daunting, but really, if 322 people donating just over $6 each, the money will be raised and we can start cleaning up our mistakes and making the world better for the future. As of the 27th of June, they have raised $878,000+ and have 77 days to go. Please donate if you can by clicking here or on the bolded link above, or reblog this and share it anywhere and everywhere you can to raise awareness! 

You can also contact Slat and his team and apply to work with them by clicking here. If you have more questions, please visit the website or check the FAQ

 

Hey guys! Awesome news! With 67 days to go on the fundraiser, the Ocean Cleanup project is officially halfway funded! Just over $1 million has been raised.

To everyone who’s donated or even just spread the word so far: Thank you so much! We still have a long way to go, so please keep helping out. 

Update #2: Just under a month left (28 days), and Slat and his team have received almost 1.5 million dollars of their $2 million goal! That is so exciting. Please continue to share this message and help fund the biggest ocean cleanup project of our generation!
