Cartilaginous Fish | Chondrichthyes

Chondrichthyes refers to a class of fish or vertebrates that feature paired fins and an internal skeleton composed of cartilage. Noticeable characteristics of cartilaginous fish include the capability of numerous species to breathe through gills and spiracles, skin dressed in dermal denticles to give protection, a small brain with several sensory organs, and an adaptive immune system. Additionally, these fish lack swim bladders, are often predatory, and show jaws and paired appendages. They are likewise an excellent source of food for humans. Chondrichthyes are further divided into Elasmobranchii and Holocephali and can be found both in freshwater and marine environments.

Goblin Shark
Scale illustration of an average Goblin Shark with dimensions for height and length compared to a human

The Goblin Shark (Mitsukurina Owstoni) is a species of shark that is often referred to as a living fossil as their ancestry can be traced back extensively. They have sharp tiny teeth that are arranged in multiple rows and a long and flat snout that resembles a sword blade. Goblin Sharks have a unique protruding jaw that extends rapidly to catch prey.

Goblin sharks live in the deep waters of the Atlantic, Pacific, and Indian ocean. They generally eat fish, cephalopods, and crustaceans near the sea floor. Not a lot is known about these sharks since they are mostly solitary and are rarely seen.

Goblin Sharks have a total length between 5’-12.5’ (1.5-3.8 m) and an overall weight in the range of 330-463 lb (150-210 kg). The typical lifespan of the Goblin Shark is between 30-35 years.

Australian Ghost Shark
Comparison illustration of the size of a Australian Ghost Shark to a typical person

The Australian Ghost Shark (Callorhinchus Milii), also known as a chimaera, is cartilaginous fish related to the shark. Ghost Sharks have 1 gill on each side of their body and have eyes that are lined with a reflective tissue that appears to glow. Their skeletons are made out of cartilage and lack scales.

Ghost sharks live in the cool waters of the continental shelves around the world. Ghost sharks typically eat small fishes and invertebrates. Not much is known about the ghost shark as they haven’t been studied much in their natural habitat.

Australian Ghost Sharks have a total length between 26”-49” (66-125 cm) and an overall weight in the range of 6.6-8.8 lb (3-4 kg). The typical lifespan of the Australian Ghost Shark is between 10-15 years.

Nurse Shark
Dimensioned comparison drawing of the Nurse Shark compared to an average person

Nurse Sharks (Ginglymostoma Cirratum) are a species of shark that moves slowly, are bottom-dwellers, and have a smooth gray-brown skin that sets them apart from other sharks. They live along the western Atlantic and eastern Pacific oceans. Nurse sharks ranked fourth in the documented shark attacks to humans.

They are nocturnal and rest along the seafloor during the day. The mouth of the Nurse Shark is filled with thousands of small sharp teeth and their diet consists of shrimp and squid. It is not exactly known what their current population trend is as it has been claimed as data deficient.

Nurse Sharks have a total length between 7.5’-10’ (2.3-3 m) and an overall weight in the range of 200-330 lb (91-150 kg). The typical lifespan of the Nurse Shark is 15-25 years.

Megamouth Shark
Dimensioned comparison drawing of the Megamouth Shark compared to an average person

The Megamouth Shark (Megachasma Pelagios) is a deep-water shark that is distinguished by its large head and mouth with rubber-like lips. It is the smallest of the filter-feeding sharks, following the Whale Shark and Basking Shark. Megamouth sharks are not typically seen as they live anywhere between the water surface and the deep-sea floor.

They live the in the Pacific, Atlantic, and Indian oceans and have been mostly found in Japan, the Philippines, and Taiwan. Megamouth sharks generally eat plankton, shrimp, copepods, pelagic jellyfish. Their life expectancy is not known, but it is believed their age can be determined by counting the growth rings on their vertebrae.

Megamouth Sharks have a total length between 13’-18’ (4-5.5 m) and an overall weight in the range of 2000-2700 lb (907-1225 kg). The lifespan of the rare Megamouth Shark is still unknown.
