Scientific name: Hippoglossus slenolepis

So, this is Hallie!

Don’t let the pic fool you, Hallie is a fierce and confident 25 year old female, who measures about 80 inches long and weighs almost 300 pounds!   Halibut can reach upwards of 500lbs, and can live more than 50 years!

Gender is not always externally obvious in halibut, so the only real way to tell is to examine the inside to look for ovaries or testes.   However, one major difference between male and female halibut, and one that would give Hallie away as a female, is their size.   Female halibut grow much faster, and get much bigger than males, who rarely weigh above 100 pounds!

Halibut enjoy different sexual partners each year, and females reproduce annually after about the age of 11.   Males can reproduce earlier in life, for some at about 8 years old.   Once a female is ready to reproduce, she can lay as many as 4 million eggs a year!

Halibut are top predators, eating essentially anything that gets in their way, and can fit into their mouths.   For a mature halibut, like Hallie, favorites include various finfish, octopus, crabs, clams and even smaller halibut!

Halibut are not, however, at the very top of the food chain.   Their predators include lings, salmon sharks, orcas, sea lions and especially humans!   Halibut is a favorite for humans because of its mild taste, firm texture and its meat’s appealing appearance.

Hallie likes to hang out near the ocean bottom, preferably above sand, mud or gravel bars.   The tops of their bodies are dark colored, and the underside is white, both of which serve as camouflage and aid in hunting.   Here is a link to a video of beautiful halibut, just like Hallie.

She spawns between November and March typically at a depth of between about 600 to 1500 feet.   The eggs are deposited into deep ocean currents where they drift until they eventually move up and into coastal waters to mature.   During the rest of the year Hallie, and other halibut prefer to be closer to shore, in shallower water.   Halibut migrate in a clockwise motion along the pacific coasts, reaching as far north as Nome, Alaska, as far south as California and as far west as China!

  1. Great set of info!! It is very apparent that you are a very creative writer! Perhaps for the next blog let’s aim to write an essay as if it was going to be published as a newspaper article and let’s try to have at least one reference from a peer reviewed journal — you can find them on Google Scholar


    1. Oh, I thought we were doing a social media type thing, or trust me I wouldn’t have written it that way. I actually struggle with creative writing. I will absolutely use an essay format for future assignments, and thanks for the feedback.

  2. Here are some pointers for your next article:

    1st Paragraph(section) —- In your introduction give us the broad picture with focus on the topic being discussed — guide us as to why we should care about the article that you are about to write — Be concise and factual and perhaps cite 1-2 references from a PEER-REVIEWED journal that you can find free to download on Google Scholar.

    2nd Paragraph or (section) Focus on the problem — e.g., Warming climates are changing habitats and causing relocation of species which can impact the ecological balance of natural systems within that ecoregion.

    3rd Paragraph or (section) –Talk about the research or what is being done to address the problem

    4th Paragraph or (section) — Give a conclusion –if the problem is not resolved you might give ideas of what can be looked at that will help us to better address the problem.

    Here is an example of how you will cite a peer-reviewed journal article


    Von Hippel, F. A., & Weigner, H. (2004). Sympatric anadromous-resident pairs of threespine stickleback species in young lakes and streams at Bering Glacier, Alaska. Behaviour, 141(11-12), 1441-1464.
