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 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 ·…

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…

Otolith Age and Growth – Lab Report

Megan DeMatteo | Fisheries Science & Management Stockton University| May 3, 2019 Abstract The main objective of this study was to obtain a better understanding of otoliths, understand their important role in conducting research, and understanding the relationships between their growth rings and fish size. In this laboratory experiment otoliths will be identified, removed, embedded, polished, and analyzed to properly read through several microscopic lenses.  The data collected was otolith length, width, and measurements were taken for each growth ring within their secondary growth center. When this data was compared to the overall fish size the results shown were a positive correlation between otolith growth and fish size. In simpler terms this means that as the fish grows so did its otolith rings. Another factor taken into consideration was although the data did show a positive relationship, once the fish…

A World of Plastic

Marine debris is any man-made solid material that has been directly or indirectly, intentionally or unintentionally, disposed or abandoned into the marine environment (NOAA, What is marine debris?). 60% to 80% of all marine debris is composed of plastic (Derraik 2002). Plastics are lightweight, durable, and cheap synthetic organic polymers. This has allowed them to…

New Ways of Propulsion Discovered in Humpback Whales

Humpback whales have always been characterized by their large pectoral fins. In fact their scientific name, Megaptera novaeangliae, translates to “big winged New Englander,” paying homage to their nearly 15 foot fins. These fins are specifically designed to be extremely hydrodynamic, allowing for easy movement through the water, despite their size. They are so efficient, that…

Changing Sea Surface Temperature and Atlantic Menhaden (Brevoortia tyrannus) abundance and its effect on the abundance of the Atlantic Bottlenose Dolphin (Tursiops truncatus) and Humpback Whale (Megaptera novaeangliae) in Cape May, New Jersey

Background: As the fall progresses in Cape May New Jersey the sea surface temperatures in the waters surrounding the southern tip of New Jersey begin to drop steadily. Beginning at around 70 degrees in September and dropping to around 40 degrees in December. Many fish species are year round residents in the area and are…

Humpback Whale Recollection – 08/26/2016

On August 26, 2016 at 1pm, we left the dock at Utsch’s Marina and headed through the Cape May harbor towards the Cold Spring inlet. I was hoping to see many dolphins and whales because it was my last day interning at the Cape May Whale Watch and Research Center for the season. We proceeded out…
