The Hydrodynamic Head of Hammerhead Sharks

When interning on a whale watching boat, of course the main goal is to find and spot some whales and dolphins. For me, I was always secretly hoping that on our outing we would come across my favorite marine animal, sharks. My wish came true and my favorite day on the boat turned out to…

Don’t Release Your Balloons!

Here at Cape May Whale Watch and Research Center we participate in the Clean Ocean Initiative. Each time marine debris is spotted during the cruise we collect it and record the day, weather conditions, as well as take a picture of the debris. Balloons are our most collected piece of debris. It is important to…

Deep Sea Adventures and Deeper Sea Divers

When I was invited to intern for the 24-hour pelagic trip that was planned for June 3-4, 2022, I knew it was an opportunity I could not refuse. The chance to be on a boat for an entire day searching for offshore marine mammals, pelagic birds and other organisms seemed too amazing to turn down,…

The Mystery of the Oceanic Sunfish (Mola mola)

One of my most impactful experiences happened aboard the American Star on May 26, 2022. It was my third day as an intern at the Cape May Whale Watch and Research Center and Icould not wait to get out into the open waters. As we were leaving the inlet to enter the AtlanticOcean, that’s when…

Horseshoe Crab Spawning in New Jersey

The Atlantic Horseshoe Crab, also called by the scientific name Limulus polyphemus, are prehistoric animals that have been on Earth for millions of years. They are in the Phylum Arthropoda. The horseshoe crabs’ structure dates 245 million years ago in the Carboniferous Period and they are more closely related to spiders, ticks, and scorpions (Tanacredi, Bottom & Smith…

The Bottlenose Dolphin: Almost Human?

The bottlenose dolphin (Tursiops truncatus) is a remarkable marine mammal known for its unusually high level of intelligence. In fact, the bottlenose dolphin is the second most encephalized being on the planet after humans, meaning that they have a very large brain-to-body ratio (Grimm, 2017). The encephalization quotient (EQ) is defined as the ratio between predicted and observed brain mass for an animal of a given size. This large brain size along with other complex portions of the brain account for the great intelligence of this species. Encephalization quotient data actually suggests that the level of intelligence in the bottlenose dolphin is closer to the human range than are our nearest primate relatives (Reiss et al., 1997). So how different is dolphin cognition and psychology from humans? Bottlenose dolphins exhibit a lot of intellectual behavior similar to humans such as…

The Impending Extinction of the Vaquita

In 2017, I purchased one of my first travel mugs. A percentage of this purchase went to fund conservation of the vaquita (Phocoena sinus), which is a small porpoise endemic to the Gulf of California in Mexico (Porpoise Conservation Society). I still use this mug today- I’m using it as I write this blog post. When I bought the travel mug, there were fewer than 30 vaquitas left. In 2021, this estimation has dropped to less than 10 (IUCN). What is a vaquita? In Spanish, “vaquita” translates to “little cow.” Vaquitas are the smallest cetaceans on Earth, and are identifiable by dark rings around both eyes and dark patches at the mouth reaching back toward the eyes (World Wildlife Fund).  The species was not discovered until 1950, when a vaquita skull was found on the northern shore of the Gulf…

PCB Bioaccumulation and Cetaceans

What are PCBs? PCB stands for Polychlorinated Biphenyls, and represents a grouping of man-made chemicals that consist of carbon, hydrogen, and chlorine. PCBs were first produced in the late 1920’s / early 1930’s, and were continued to be used in products until its ban in 1979 (Toxic Substances Control Act) due to the toxicity of PCBs and its negative impacts on biological organisms. There are a range of PCBs, with varying consistencies (from a thin liquid to a thick wax) as well as varying degrees of toxicity. PCBs were very popularly used in a large variety of products due to their “non-flammability, chemical stability, high boiling point, and electrical insulating properties” (EPA). Some examples of products listed on the EPA’s website for things that previously contained PCBs include: · Pigments and dyes · Oil-based paint · Caulking · Plastics ·…

Sea Turtle Nesting Impacts

Conservation efforts and research efforts on the American Star mainly focus on our marine mammal species. Another species that is seen during trips off the coast of Cape May are sea turtles. There are seven species of sea turtles found in the world which include, leatherbacks, loggerhead, green turtles, kemp’s ridley, olive ridley, hawksbill and…

The Cownose Ray 

    The Cownose Ray, Rhinoptera bonasus, gets its name from the shape of its forehead, which resembles the nose of a cow. The top of the ray is a brown color, and the bottom is white. Females are 3 feet in width, and males are 2-and-a-half feet in width. They have long whip-like tails with…

The Great Hammerhead Shark

Sphyrna mokarran, or the Great Hammerhead Shark, is an endangered species within our oceans. Like many other species, these large sharks can be caught and trapped within beach nets and even fishing nets. These beach nets are used as a guard between humans and sharks, to keep as many sharks away from humans as possible….

The Breach of a Lifetime

5/15/21 – CMWWRC Database On May 15th, 2021, I witnessed a very rare event. Some would even say it was once in a lifetime sight. It seemed like just a normal day on the water while interning on the American Star for Cape May Whale Watch and Research Center. But, halfway through our trip, we…
