Lobsters don't have tentacles :P But they do have five pairs of legs.
Isopods are crustaceans, as are lobsters. Crustaceans are a class in the phylum Arthropoda. Fish, however, are a class in the phylum Chordata, or vertebrates. So, not related to isopods, or lobsters. ^^
Lobsters are not fish. Fish are part of the phylum Chordata, along with other backboned animals (amphibians, reptiles, birds and mammals), and lobsters are arthropods (phylum Arthropoda :P), having no backbone and being completely unrelated (very much related to insects in fact). Lobsters have ten jointed legs and a hard carapace.
Lobsters
The question isn't correctly phrased... Butterflies and lobsters both belong to a phylum called. "Arthropoda", which means they both have an exoskeleton, a segmented body, and jointed appendages. Both creatures, however, are from separate classes. Lobsters belong to a class called, "Malacostraca", which is a subset of crustaceans with a wide diversity. Butterflies belong to a class called, "insecta", which all have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae.
Lobsters belong to class Malacostraca, characterized by 20 body segments (rarely, 21). In lobsters, a tagma or segment group called a cephalothorax is present, a fusion of the head and thorax.
Lobsters, like all crustaceans, have two pairs of antennae.

A star fish has 5 tentacles
Lobsters have three pairs of antennae, a large pair and two small pairs. Their sensory functions differ; the largest are for touch and used for navigation. The smaller ones have highly sensitive olfactory functions to detect chemical signals, locate food etc.
Squid, have eight arms arranged in pairs and two, usually longer, tentacles.
Legs, or appendages. The forward pair have adapted to become claws, which are more arm-like than the others. Lobsters, along with crabs, prawns and shrimp, are decapods (10 legs).
Squids have four pairs of arms and a pair of tentacles. The tentacles are longer than the arms. The tentacles perform the function of grabbing prey and holding on to it. There are hooks on the arms as well as the tentacles of squids but the ones on the tentacles can swivel while those on the arm cannot. These help squids hold on to their prey better while the prey tries to escpe. Suckers are present on both the arms as well as the tentacles of squids, though the ones on the arms are bigger.
Crabs and Lobsters have a few things similar to each other. For instance, · Crabs and lobsters are seafood. · Crabs and lobsters live underground. · Crabs and lobsters have shells. · Crabs and lobsters have claws. · Crabs and lobsters live in oceans. · Crabs and lobsters are omnivores. · Crabs and lobsters come from the society of Animalia.
It acts like sense and taste organ for the lobster.
Slender man is often seen with 5 tentacles, but he is somewhat a shape-shifting creature, he can transform into something human to ghostly, he can have up to 5000 tentacles.
In actuality, slugs do not have four noses. What people perceive as four noses on slugs are really two pairs of tentacles.
Crustaceans are animals like crabs, lobsters, and crayfish. Crustaceans have two pairs of antennae, two pairs of maxillae, and mandibles, which are like jaws. They are biramous, which means their legs bend in two places.
