There are two main groups of whales: baleen whales and toothed whales. Baleen whales have fibrous baleen plates in their mouths that allow them to filter larger quantities of krill, plankton, and crustaceans. These plates are made out of keratin, which is the same protein that forms human fingernails and hair.
When a Humpback whale is born, it can weigh up to 2,000 pounds and reach up to 15 feet in length. These young whales, called calves, stay with their mothers to nurse for anywhere between 6 to 10 months, until they are about 24 to 27 feet long.
Tiger Tail Sea Cucumbers are the largest sea cucumber in the Western Atlantic. They feed on algae and detritus. Juveniles often mimic sea slugs by crawling around on the bottom slowly filtering sand through their tentacles to gather food. Once older, they can spread their tentacles above them to capture plankton. A number of sea cucumbers feed nocturnally while others feed by day. Sea cucumbers often attract hitch-hikers like shrimps and crabs that crawl over their skin. As a means of defence sea cucumbers can expel their intestines or respiratory organs in the form of sticky threads, but these can quickly regenerate
“While the fish in this photo appears to be sitting there allowing me to take his photo it was quite the contrary. He came up at me from the sandy bottom with such intent and speed that I couldn't believe I managed to get him in the frame, let alone having him and is grumpy face in focus!” Picasso Triggerfish vocalizes using a "grunting" sound.
Some rockfish can live to be 100 years or older. Most Rockfish grow very slowly and don’t reproduce until they are at least 10 years old. Believe it or not, rockfish are aged accurately by analyzing the bones in their ears! Some species of rockfish are very territorial and may stay at a ‘home site’ for years. Rockfish often extend their dorsal spines and lean towards an approaching threat. If this defensive posture fails to discourage an approaching threat, most rockfish will then head for nearby cover. Rockfish have air bladders which allow them to float motionless in the water column. This helps them to sneak up on prey very quietly to strike.
Seahorses use camouflage to avoid predators and sneakily attack their prey, which includes a variety of small crustaceans. These animals have eyes that move independently from one another which also helps them to track and ambush prey. They do not have teeth or stomachs, so they must eat almost constantly to survive.
Garden Eels live in colonies of up to 700 individuals and burrow in the sand of the ocean floor, using mucus from their bodies to prevent the sand around them from collapsing. These eels tend to stay in their individual burrows, rarely leaving to catch their prey, zooplankton, that floats by them.
Hawaiian Monk Seals got their name because the folds on their skin look similar a monk’s cowl. Additionally, like a monk, these seals tend to live in solitary. When these seals are born, they are black in color. They turn to shades of gray and brown as they mature.
Starfish can live for up to 35 years in the wild. They vary in size from one centimeter to 65 centimeters depending on the species. There are 1,600 species of starfish throughout oceans around the world and different species live in habitats including tidal pools, rocky shores, sea grass, kelp beds, and coral reefs.
These jellyfish have 8 arms that surround their mouths and help them find food. Their diet consists of zooplankton, algae, shrimp, and invertebrate eggs. Although this species of jellyfish is the most venomous, they are not harmful to humans.
Whale sharks are the world’s largest fish, reaching up to 40 feet and weighing an average of 20,000 pounds. These gentle giants can neither bite nor chew and are filter feeders. Their mouths contain hundreds of rows of tiny teeth and can open up to 4 feet wide.
