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.
Living up to about 30 years, leopard sharks can be found in shallow muddy waters, particularly Northern California. Often times they are preyed upon by larger sharks, like the Great White, but they themselves eat relatively small animals like worms, crabs, octopus, and fish. Branching off from a species of houndshark in the Triakidae family, adult leopard sharks can grow up to 6 feet long, but typically average at about 5 feet.
Did you know that batfish are actually not strong swimmers? Even with their long anal and dorsal fins, scientists know batfish to be a “sleeper species” because they play a vital role in the upkeep of coral reefs but can only do so under certain conditions.
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.
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.
The largest sea turtle, the Leatherback, can reach up to 2,200 pounds. Unlike other species of sea turtles, Leatherback turtles have a rubbery shell composed of cartilage-like tissues rather than a hard, bony shell. Leatherback turtles also live in waters of more of the world than any other sea turtle.
Tripod fish got their names because when they are still, they look like a tripod. They have three long structures that allow them to walk on the ocean floor. Their fins can reach up to 3.3 feet in length, although their bodies are only 12 to 14 inches long. They use their pectoral fins to detect what is around them in the water and to find prey because their eyes have limited abilities.
