Jelsac

From Wikitroid, the Metroid wiki

Jelsacs are aggressive, six legged Phazon based lifeforms. They slightly resemble a crab in design, with two large claws in front and its eyes fixed in the carapace. If provoked, the large balloon structure on its back will fill with a Phazon based life form. Eventually, the Jelsac explodes, spraying the poison all over.
