The world’s fastest fish is the Indo-Pacific sailfish, Istiophorus platypterus. This sport fish can swim up to 68 miles per hour by standards (a cheetah can run up to 70 miles per hour). Check out this incredible video from PBS which aired in August of 2010. Marine biologist, Rick Rosenthal, witnesses a rare moment of a sailfish feeding at night. You’ll also see a baby sailfish drawn into the light by Rick’s flashlight. Enjoy!

So you think you want to be a marine biologist?
Have you ever watched an epic movie about the sea and dreamed of being a “marine biologist” or “oceanographer”? Have you ever had thoughts after that thought about … what is the difference between a “marine biologist” and “oceanographer”? Marine biology, or the study of life in the sea, is actually just one branch of […]
Do whales and dolphins get sunburn?
According to this article from The Royal Society (published November 2010) whales are very prone to the harmful rays of the sun. The scientists discovered whales that spend more time at the surface of the sea had more skin cells exposed and therefore were showing more damage from the ultraviolet radiation. It was even pointed […]
How does coral bleaching result?
Coral bleaching is due to the fact that the algae part of the coral reef ecosystem can no longer photosynthesize properly – therfore, losing the “reef” structure and the corals remain white – since the zooxannthellea are not around (that’s the algae – and responsible for the color of the coral). This occurs due to […]
Do all ocean animals swim together in schools?
Nope, here is a short list of terms used to describe certain groups of ocean animals when they congregate together. Jellyfish swim in a smack. Whales swim in a pod. Herring swim in a seige. Penguins walking together on land is called a waddle. Have a great question that needs a concise and comical answer? […]
How do you know the difference between a male and female blue crab?
You must be brave enough to pinch the body of the blue crab from behind and lift it upside down (It hurts a lot if they pinch you!). Male blue crabs have a distinct shape like a pencil – or the Washington Monument – in the center of their bellies. Female blue crabs, on the […]
It’s as easy as A, B, Sea: H for Horseshoe Crab
Horseshoe crabs are an arthropod more closely related to spiders and scorpions than crabs and lobsters. They have a three part body: prosoma (head), opisthosoma (heavy shell with legs under it) and the telson (tail). This amazing body structure has been unchanged for over 200 million years. Interestingly enough, this is this Beach Chair […]
Who is afraid of Atlantic wolf(fish)?
The Atlantic wolffish (Anarhichas lupus) may look rather frightening, but, the fish will only harm you if it is out of water. This is rather understandable since it is out of its natural habitat. It prefers to live on rocky bottoms of the ocean floor in very deep, cold waters. These fish have high concentrations […]
Nudibranchs: The elusive butterflies of the sea
The 3,000 species of nudibranchs (noo-duh-brangk) boast more colors than a box of Crayola crayons and most nudibranchs “live no more than a year and then disappear without a trace, their boneless, shell-less bodies leaving no record of their brief, brilliant lives”. These sea slugs are found all over the world and range in size […]
My favorite posts from 2013
This isn’t the typical list of the most popular Beach Chair Scientist posts throughout the year (you can find those on the right sidebar under “Top Posts & Pages from BCS” any day of the year). Those posts typically include questions typed into a search bar such as ‘Are manatees and elephants really related?‘, ‘Do […]
Are stingrays related to sharks?
Stingrays and sharks are very closely related. They belong to a group of fishes called the elasmobranchs. All elasmobranchs have 1) skeletons made of cartilage (the flexible material that makes up the tip of our nose and ears) and 2) 5-7 gill slits. Elasmobrachs includes sharks, rays, and skates. It’s not entirely incorrect to think […]
