The wall of a jellyfish body is very fragile. Their bodies are much different then that of most animals. They have no brain, no respiratory system, and no circulatory system. The average length of a jellyfish tentacle is one to ten meters long. The tentacles of a jellyfish in some cases can grow to a massive length of 100 feet!
It has red or orange antennae, lacks hair, and its claws seem rough or grainy. This hermit crab will pick a shell it can pull its entire body back into. I saw both P. hirsutiusculus and P. granosimanus in the same tidepool at Rosario recently. A third species to watch for is Pagurus beringanus. This species is usually subtidal but may occasionally be seen in very low subtidal areas.
Most jelly fish are dangerous as they sting other creatures, when touched by one of their tentacles. Clown fish are immune to stings thus why Marlin wasn’t affected. 14. Compare Dory, Bruce and Nemo, which is the best adapted for speed and why? Bruce is best adapted for speed, as he is a shark and needs to be fast to catch and hunt down his prey.
Some manta rays live in a particular location while others travel from places to places. Manta rays are filter feeders. They consume a large quantity of zooplankton by filter seawater through their mouths while swimming. And usually many manta rays swim in lines with their mouths open to filter more zooplankton. Manta rays are huge in size so only sharks and killer whales can harm them and eat them.
A major distinction of cuttlefish from other squids is the presence of the cuttlebone. Primarily composed of aragonite, it is a porous, hard, and brittle structure found internally. The shell itself is chambered and made up of microscopic narrow layers connected by upright pillars (allthesea.com). The chambers become gas filled in the front and water filled in the rear to maintain the neutral buoyancy of the cuttlefish. The buoyancy allows the cuttlefish to hover over the floor of the oceans.
Predators eat animals they have killed. As an example, lobsters are predatory. Crabs, on the over hand, can be predators, herbivores or scavengers. They use their large claws to attack the prey. The crusher claws are used to
The Oceanic White-Tipped Shark is a pelagic shark which means it lives close to the surface and rarely goes to the ocean floor. It is an aggressive slow moving fish that usually will find a carcass of a whale or other large marine animal and dominate the feeding frenzy. It gets its Name white-tipped shark because every fin on the shark has a white tip except the anal fin which has a black tip. They inhabit most of the Salt water of the world because they can live in cold or warm water. Excluding the occasional feeding frenzy, white tips also eat a diet that consists mostly of cephalopods.
Although their venom isn’t not lethal to humans it is used to subdue and kill the prey, and they are also known to strangle their prey to death like the Boa Constrictor snakes. When this vicious snake feels threatened its first reaction is to lunge at the threatening object and attempt to bite. This snake is an above average breeder producing 4 to 12 eggs approximately twice a year. This reptile was introduced after World War II when the snake was accidently transported from the South Pacific to Guam allowing for the snake to introduce to other locations such as Florida unknowingly (Rodda, 1992). Since there are no natural predators present in
The Emperor Angelfish also known as the Imperator Angelfish is usually found in most parts of the Indo- Central Pacific Ocean and in the warmer parts of the Red Sea. They live in areas with rich coral growth Young emperor angelfishes tend to live alone, hiding in reef holes and crevices. In some parts young emperor angelfishes frequent shrimp cleaning stations and would occasionally help shrimps pick off parasites and dead skin from a fish waiting to be cleaned. The emperor angelfish is a carnivore unlike most species of angelfish that are herbivores. Emperor angelfish eats coral heads, small invertebrates like sponges, and crustaceans such as shrimp and shellfish.
These reptiles have the ability to do incredible things. The Green Sea Turtle is one of seven species and happens to be the largest member of the Cheioniidae family. According to www.turtles.org/hawgrnd.htm , scientists assume that post-hatchlings, pelagic-stage Green Sea Turtles are omnivorous, but there are no data on diet from this age class. Young Green Sea Turtles have a diet of jellyfish and other invertebrates. Adults tend to eat sea grass and algae.
